Longevity

October 20, 2026

Inside the front section of last week’s newspaper was a Reuters article about the world’s oldest-known terrestrial animal. Jonathan is an Aldabra giant tortoise estimated to be about 194 years old. The tortoise was likely from the Aldabra Atoll and brought to the remote South Atlantic island of St Helena as a fully grown animal in 1882. The tortoise now resides in a paddock at Plantation House, the governor’s residence. “Other Aldabra tortoises have been claimed to have lived as long as Jonathan, but he has the most documentary evidence supporting his age,” said Benjamin Vaisvil, a researcher affiliated with the organization Kallel and co-lead author of the study published on October 7tn in the journal Science Advances. Scientists have studied Jonathan for the animal’s longevity, sequencing his genome and analyzing his chemical markers that control which genes switch on and off (epigenome). “We found changes in Jonathan’s genome in pathways associated with longevity, like DNA repair, mitochondrial function, insulin ⁠regulation and telomere function.”

When I went online, I found the Aldabra giant tortoise (Aldabrachelys gigantea), or Aldabra tortoise, is a species in the Family Testudinidae and genus Aldabrachelys. The tortoise is endemic to the Seychelles islands located in the western Indian Ocean, northeast of Madagascar and roughly 1,000 miles (1,600 km) east of mainland Africa. The first scientifically described (nominate) subspecies (A. g. gigantea) is native to Aldabra atoll. The tortoise’s upper shell (carapace) is brown or tan in color with a high, domed shape. Males’ carapace averages 48 inches (122 cm) in length and have an average weight of 550 pounds (250 kg). Females are generally smaller with and average carapace length of 36 inches (91 cm) and weighing 351 pounds (159 kg). [The species has stocky, heavily scaled legs to support its heavy body. The neck is long, which helps the animal to feed from tree branches 39 inches (1 m) from the ground. The species is one of the largest tortoises in the world.

Despite his age, Jonathan retains a voracious appetite, lifting his head and stretching out his long neck when the veterinarian calls his name. “I know he knows me, knows my voice and my handling, and ⁠I also know it isn’t love on his part but a recognition of the arrival of a feast,” said longtime veterinarian and study co-author Joe Hollins. Jonathan has lived through world wars and the rise and fall of empires. “He is symbolic of resilience, longevity, endurance, a persistent presence throughout huge historic events,” Hollins said. Giant tortoises were historically found on many of the western Indian Ocean islands, as well as Madagascar, and the fossil record indicates giant tortoises once occurred on every continent and many islands, except for Antarctica. Many of the Indian Ocean species were thought to be driven to extinction by over-exploitation by European sailors, and they were all seemingly extinct by 1840 except for the Aldabran giant tortoise on the island atoll of Aldabra, although some remnant individuals may remain in captivity.

Thoughts: I remember visiting a petting zoo as a small child that featured a giant tortoise that you could ride. I watched as little boys climbed on and then kicked the shell yelling, “Yah!”, trying to make the animal move faster. This was despite a sign requesting you refrain from kicking. I now wonder if the captive animal was happy with its longevity. Humanity’s quest for longevity has shifted from ancient myths of immortality and the elixir of life to a multi-billion-dollar scientific and biotech pursuit focused on extending healthspan (years free of chronic disease) rather than just lifespan. Life expectancy in the US reached 79 years in 2024. Scientists note human life expectancy maximizes around 85 years, with a hard maximum human lifespan around 122 years. We need to live the life we have to the best of our ability. Act for all. Change is coming and it starts with you.

Leopard Frog

September 30, 2026

I have mentioned how Loki is now on constant lookout when he first goes into the backyard. He jumps down and sniffs both sides of the exit ramp before moving on to grass beneath the bay window. Next, he moves on down the house to the storage box next to the vegetable bed. He has good reason to be frantic as several times he has almost caught the Woodland Vole (Microtus pinetorum) that lives under the ramp and feeds off the seeds dropped out of the feeders by the birds. This morning Loki was so intent on sniffing the ramp he failed to notice the house mouse (Mus musculus) that scurried across the cement deck and down a hole next to the pool. I went over to replace the window feeders I take down every night to discourage the raccoons (Procyon lotor) return and notice movement at my feet. When I looked down, I saw a different species of frog. This was not the gray tree frogs (Hyla versicolor) or the American bullfrogs (Lithobates catesbeianus) that croak during breeding season. This was another common resident, the southern leopard frog.

When I went online, I found the southern leopard frog (Lithobates sphenocephalus) is a medium-sized amphibian (anuran) in the family Ranidae (true frogs). The species is one of 36 species currently or formerly classified in the Rana genus found in North America. It is native to eastern North America from Kansas to New Jersey to Florida and is an introduced species in some areas (California). Individuals are up to 5.1 inches (13 cm) long. Mature males average 2 inches (53 mm) snout to rear (vent) length and females average 2.5 inches (64 mm). The leopard is green or brown in color, has a yellowish ridge along each side of the back, rounded dark spots on the back and sides, and a light spot on each ear (tympanum). The male has larger fore limbs than the female. A breeding male’s vocal sacs are spherical when inflated with a “ratchet-like trill” or “chuckling croak” for a call.

I had just enough time to snap a photo of the leopard frog before Loki continued his search along the back of the house. As Loki approached the bay window, the frog took note and began to hop away. That alerted Loki to the frog’s presence and he rushed after it. The leopard frog was fast and hopped into the red canna lilies (Zantedeschia rehmannii) that dominate the center of the area. Now lost in the foliage, Loki could only snuffle back and forth with a soft whine. I did not mind the presence of the southern leopard frog as they feed primarily on insects, crawdads (Procambarus clarkii), and other invertebrates. Our pool has long shrunk in size during the summer heat and no longer supports the gray treefrog tadpoles that teemed there this spring. The leopard moves away from the water during the warmer months and is away from water most of the time as they forage in upland areas. This is a welcome addition to help clear pest from my garden and containers.

Thoughts: While the leopard frog is common to our area, this is the first one I recall seeing in our back yard. Our pool/pond is not conducive for breeding, and I have never seen the egg clusters that float among the low foliage where they like to breed. Since there was only one frog, I assume it was foraging away from its water source, probably the Crooked Creek about 400 yards (366 m) to the south. The eggs masses can hatch from 4 days to two weeks and hatch more quickly in the presence of predators like crayfish. That means crawdads eat leopard frog eggs that grow to feed on small crawdads. This is part of nature’s irony. Humans need to be more observant of our earth mates and learn about how diversity drives us all. Act for all. Change is coming and it starts with you.

Burrow

September 24, 2026

Melissa’s parents owned a minivan with a wheelchair lift on the back. It was a 2006 model but had low mileage. They purchased the van used in 2015 from a lift dealer who said the previous owner used to for shopping and doctor’s appointments. They used it more extensively, but it never driven much. When we moved back to Arkansas the van was parked next to the workshop. The van sat for several years until we decided to donate it to a church program which connects people in need with low-cost cars. We called to have the van towed but the dealer never called back to get the vehicle. After several tries, I gave up and the van sat for another two years. The program is now associated with another repair shop and we connected again. A recovery group was looking for a van to transport clients back and forth from a residence house to appointments. Melissa called this time and within two days they came and towed the van. Since it had sat for so long, a pile of pine (Pinus echinata) needles collected under the van. Several days later I went to clean the area and notice an 8-inch (20 cm) hole in the middle of the debris. An animal decided this was perfect for their burrow.

When I went online, I found a burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of the animal moving through the ground. Burrows provide a form of shelter against predation and exposure to the elements and can be found in nearly every biome and can represent both symbiosis (cooperation) and competition. Many animal species are known to form burrows and range from small amphipods (crustaceans) to very large vertebrate species such as the polar bear (Ursus maritimus). Burrows can be constructed into a wide variety of substrates and can range in complexity from a simple tube a few inches/centimeters long to a complex network of interconnecting tunnels and chambers hundreds or thousands of yards/meters in total length, such as a rabbit (family, Leporidae) warren. Mammals are the most well-known species for constructing a burrow.

When I saw the burrow, I knew why the kids were barking at the fence facing the workshop. I had assumed it was the neighborhood cats (Felis catus), but I have not seen one in several months. They have also been barking at the raccoons (Procyon lotor) and opossum (Didelphis virginiana) in the trees and walking along the top of the fence, but neither species is known to make a burrow. When I searched for the owner online, it provided the top three species as a fox (Urocyon cinereoargenteus), a woodchuck/groundhog (Marmota monax), or a nine-banded armadillo (Dasypus novemcinctus). These are all good-sized mammals, and I could not believe any would be living under our van for long without either of us seeing it. While I did not want to (necessarily) get rid of the creature, I called the town’s animal control officer to see if she could provide insight into what could be living in our yard. When I described the burrow, she immediately suggested it was probably an armadillo. Since this was one of the three animals suggested online, I am assuming that is what we have.

Thoughts: An armadillo living in the burrow is supported by the holes that have been popping up in our yard and garden containers. Armadillos like soft soil that is easy to dig, and our lawn and garden provide grubs, beetles, and spiders that can be found on the surface and first layer of soil. Since the burrow is no longer covered by the van, I am hoping the animal will find a new living location. Joe Ray is a hermit who spent years living in a system of caves in the Ozark Mountains and was documented by National Geographic TV in the series The Boonies. Other Ozark residents also lived in the Ozark caves during the Depression. Now modern conversions like the Beckham Creek Cave Lodge in Parthenon, Arkansas, have turned historic or custom-built caves into luxury rentals. We are not far from our ancestors. Act for all. Change is coming and it starts with you.

Virile

September 07, 2026

Last month my local newspaper carried a USA Today article about the non-native crayfish (Family, Cambaridae) who are massing below Glen Canyon Dam for a potential invasion of Grand Canyon. National Park Service (NPS) biologists say the invasive species has caused ecological havoc in other streams and has now shown up by the thousands in agency nets below the dam. There have been more than 3,000 netted so far this year in a short stretch of the Colorado River where last year they found just over two dozen. NPS Colorado River Coordinator Nicki Gibney also reported a boom in non-native fish, including bluegills (Lepomis macrochirus) and sunfish (Family, Centrarchidae). These invaders and the crayfish are thought to have slipped through the dam’s hydropower turbines and are benefiting from the warm water the dam releases as long-term drought and water demand pushes Lake Powell’s warm surface closer to the power plant’s intakes. This same phenomenon has favored smallmouth bass (Micropterus dolomieu), which the government has taken emergency measures to keep from reaching and eating rare native fish in the Grand Canyon. While several species of crayfish are present, the dominant species is the virile.

When I went online, I found the virile crayfish (Faxonius virilis) is a species of crayfish also known as the northern crayfish and eastern crayfish. The species was reclassified in August 2017, and the genus changed from Orconectes to Faxonius. The virile is native to the central US, east to tributaries of Lake Erie, Lake Ontario, Lake Champlain and the St. Lawrence River in New York and much of Canada. Individuals can be found hiding from predators under stones and logs in lakes, streams, and wetlands. They are identified by the brown or rust-red carapace (cephalothorax) and large pinchers (chelipeds), which are usually blue in color. Crayfish can grow to 6.9 inches (17.5 cm) in length, and their walking legs have a small claw at the end. The virile feeds on a wide range of invertebrates and plants, along with tadpoles and even small fish. Faxonius virilis is used as fishing bait, as food for humans, and as aquarium food for carnivorous fish. The virile has become an invasive species in parts of North America outside their native range and was discovered in the UK in 2008. It is listed as a species of Least Concern on the IUCN Red List.

The virile crayfish is an especially vexing invader because it can march uphill around cascades that fish might not reach, Southwest Wildlands ecologist and work group member Larry Stevens said. Stevens called this, “an existential threat to the last remaining pristine streams — some of the last ones — in the West. Crayfish are dominant in many of the streams in Arizona and Utah.” The virile represents another developing threat to the Grand Canyon’s nature in a time when climate change is challenging the government’s ability to react. After two summers of releasing cold shocks of water to prevent bass spawning and protecting the park’s humpback chub (Gila cypha) population. The Interior Department’s Bureau of Reclamation announced they could not spare the water this summer as Lake Powell’s decline is threatening the dam’s ability to produce power. Without the aid of cold water, officials are electrofishing and netting in the river to remove invasives.

Thoughts: The influx of the virile crayfish and other warm water invasives illustrate another aspect of how climate change is impacting native populations. Warmer temperatures allow invasive species to move farther north and draught forces agencies to choose between the demands of humans and the needs of local ecosystems. Earth’s hottest year on record is 2024, with 2023 and 2025 tied at second. Models suggest 2026 is likely to break those records. Climate change about fluctuating extremes more than just warmer temperatures. In the US we have floods in the East and draughts in the West. The rest of the world faces similar patterns. Act for all. Change is coming and it starts with you.

Prarie Lizard

August 26, 2026

I started late this morning and the “feels like” temperature was already 101F (38C), so even the shaded park path seemed too much for the kids (and me). I knew the brief rain we got last night was not enough to keep my seed damp in the sun. The sparrows (Passer domesticus) and finches (Haemorhous mexicanus) scattered as I walked onto the pool deck to fill the feeders and give my plants a shot of water. The birds had attacked several of the tomatoes (Solanum lycopersicum) I was letting ripen on the vine, so I picked the ripe fruits (about 20) along with 10 red jalapenos (Capsicum annuum). Next, I went out to give the seeds in the raised bed a good drink. As I walked back to turn off the hose, I caught rapid movement across the sidewalk and then the mulch near the faucet. I stopped and caught another quick movement up the wall. Hidden on the wall and covered by the phlox (Phlox paniculata) was an eastern prairie lizard.

When I went online, I found the eastern prairie lizard (Sceloporus consobrinus), also known as a fence lizard, is a species of lizard in the family Phrynosomatidae. Distribution in the US extends from far western Nevada east to New York and from southern South Dakota in the north into Mexico to the south. Prairie lizards can be distinguished by the combination of highly keeled, pointed, and overlapping scales; no “horns” at the back of the head; and a tail longer than the body. Coloration and pattern can be highly variable, even within local populations. The top (dorsal) coloration can be gray, brown, or a mixture of gray, brown, and white, and chevron-shaped lines can be present or absent and may have a distinct gray stripe along the midline of the dorsal body surface. Lighter stripes may be well to poorly defined on lateral body surfaces extending from the neck to the first one-third of the tail. Adult males have distinct green-blue patches bordered by black on each side of the under (ventral) body surface. In larger males, the underside of the jaw may be black with green-blue patches on either side of the throat. Prairie lizards reach just over 3 inches (7.5 cm) in snout-vent length (plus tail) while hatchlings are about three-fourths of an inch (2 cm) in snout-vent length.

Prairie lizards can be active during any month of the year if temperatures are high enough but are most active during March to October and are found in almost every terrestrial habitat. The color and pattern variations (ectomorphs) are often associated with the microhabitats where they live. During the breeding season (late spring to early summer), males are territorial and aggressively interact with other males. Females deposit clutches of 6 to14 eggs from early May through July and may deposit more than one clutch per season. Eggs are deposited in shallow burrows in the ground, under surface objects, and possibly in the walls of mammal burrows. There is no parental care. Eggs hatch from late July through September. Lifespan under natural conditions is unknown but individuals (likely) can live up to four years. These lizards are “ambush foragers” and eat a variety of insects. They rely on relatively high body temperatures (about 95F/35C) for activity and are often observed basking in direct sunlight. Their primary defensive behavior includes a combination of camouflage (crypsis) and short, rapid retreats to crevices, shrubs, or other safe harbors once they have been detected.

Thoughts: The Prairie lizard can be observed by remaining still for 5 to10 minutes in their habitat and watching for movement. I watched for about 1 minute trying for a better photo and it never moved. Not moving is not always a good strategy. Warm-blooded predators (dogs and bears) see your body heat and the sound of breathing can be picked up by ears. Animals with a strong sense of smell (like dogs) find you by the air. Humans instead make loud noises and band together in packs. It helps that we are at the top of the food chain. Act for all. Change is coming and it starts with you.

Carnivorous

August 05, 2026

My NYT feed The Morning included a blurb about the vindication of Charles Darwin’s hypothesis about carnivorous plants. Darwin called Venus flytraps (Dionaea muscipula) “one of the most wonderful plants in the world” and once remarked that he cared more about sundews, plants that sport sticky, flypaper-like traps, “than the origin of all the species in the world.” Darwin published a treatise on carnivorous plants in 1875 that featured several species he thought could be flesh-eating flora, including the hardy alpine plants (genus Saxifraga) that had sticky hairs. Darwin tempted two European Saxifraga species with insects during feeding experiments, but he was unable to prove they were carnivorous. Scientists have now vindicated Darwin’s hypothesis. A team of researchers recently served tiny flies to another Saxifraga species native to China. Their findings were published on Tuesday in the journal Nature Communications revealing the Saxifraga candelabrum does digest and absorb sustenance from trapped prey, expanding evidence of a new family of carnivorous plants.

When I went online, I found Saxifraga candelabrum is a species of flowering plant in the family Saxifragaceae native to northwestern Sichuan and northern Yunnan, China. Candelabrum is a perennial herb reaching 6 to 15 inches (15 to 38 cm) in height. The species grows in a variety of habitats, including forests, forest edges, high meadows, and rocky crevices at elevations from 6,600 to 13,800 feet (2,000 to 4,200 m). The 2026 study found that it is carnivorous, trapping insects in the glandular hairs of its leaves and digesting them. The plant’s flowers attract tiny flying insects in the dipterid suborder Nematocera (aka gnats) and traps them with their sticky glandular hairs. Larger flies (order Diptera) are too big to be captured and instead serve as flower pollinators. The Saxifraga candelabrum can attract, trap, digest, and absorb nitrogen from insects, supporting a prediction made by Charles Darwin more than 150 years ago.

Many plants exhibit carnivorous traits like prey capture, but to be formally classified as carnivorous they must show adaptations for attracting, catching, digesting, and absorbing nutrients from prey. Hang Sun and colleagues studied Saxifraga candelabrum and field observations and surveys of existing plant samples showed that insect prey was present on the glandular hairs of 43 out of 45 surveyed specimens. Mature plants displayed an average of 71 trapped insects, predominantly on these hairs. The authors used fluorescence tagging to identify a digestive enzyme (phosphatase activity) found in carnivorous plants, suggesting that the plant can potentially digest prey. Small flies (genus Drosophila) labeled with a stable form of nitrogen were fed to the plant to analyze whether it could absorb the prey’s nutrient. The authors observed a notable rise in labeled nitrogen levels among candelabrum and control plants from another carnivorous species, and no rise in the non-carnivorous controls. Genetic analysis also found genomic similarities with other independently evolved carnivorous plants. These findings provide strong evidence to support Darwin’s hypothesis.

THOUGHTS: Carnivorous plants have independently evolved in 14 families of flowering plants and are defined by the trapping and digesting of prey for nourishment. Being a meat eater allows a plant to live in depleted soil and harsh habitats. Humans have an even greater advantage as they can eat both meat and plants (omnivorous). This flexible diet helps us survive when one food source is scarce or when the environment changes. However, we cannot digest tough plants as herbivores do and are less skilled at catching fast or dangerous prey as carnivores. Humans have instead learned to adapt to their environment more than being shaped by it. Now we need to ensure our adaptation does not destroy the environment. Act for all. Change will come and it starts with you.

Pearl Crescent

July 20, 2026

As June moved into July my tomatoes (Solanum lycopersicum) began to produce, and I was able to take over 50 pounds (22.7 kg) to two local food banks. I also canned 7 quarts (6.6 L) of the Romas into pasta sauce and turned 2 pounds (0.9 kg) of the sweet 100’s cherry tomatoes into a jar of sun-dried tomatoes. I had never made sun-dried tomatoes before and was surprised how easy they were to make. I cut off the ends and halved each fruit, then coated them with olive oil and Italian seasoning. I placed the halves skin-side down in our air fryer for 40 minutes at 250F (121C). The recipe suggested I add another 40 minutes at 180F (82C) to get the chewiness found in store brands. The lowest setting on my air fryer is 250/121, so I hedged and put them back for another 30 minutes. I put them in a clean (airtight) jelly jar and into the refrigerator. This should last several months. This last week the heat of summer finally found us and while my tomatoes have slowed down, my jalapenos have begun to take off. When I went out yesterday morning to water and check for ripe fruit, I noticed a new butterfly resting on the tomato leaves. This was a pearl crescent butterfly.

When I went online, I found the pearl crescent (Phyciodes tharos) is a species North American butterfly. It is found in all parts of the US except the west coast, and throughout Mexico and parts of southern Canada. The species reside in open areas such as pastures, road edges, vacant lots, fields, and open pine woods. Color patterns can be quite variable. Males usually have black antenna knobs. The upper side is orange with black borders, while the rear (postmedian) and submarginal areas are crossed by fine black marks. The underside of the hindwing has a dark marginal patch containing a light-colored crescent. The wingspan is from 0.8 to 1.3 inches (21 to 34 mm). Adults find nectar from a wide variety of flowers including dogbane, swamp milkweed, shepherd’s needle, asters, and winter cress. Males patrol open areas for females, and the eggs are laid in small batches on the underside of host plant leaves of aster species (family Asteraceae). Caterpillars eat the leaves and are gregarious when young. Hibernation is by third-stage caterpillars. The species has several broods from April to November in the north, and throughout the year in the deep south and Mexico.

Hybridization between the pearl crescent and other species of the genus Phyciodes have been studied in the past. These studies were done to see whether variation through hybridization could arise and create a new species of Lepidoptera (butterflies and moths) as a result. The pearl crescent has a large distribution (Mexico to Canada), and around the US/Canada boarder three other species of Phyciodes (P. batesii, P. cocyta, and P. pulchella) are present. While all these Lepidoptera share the same genus their genomes are distinct, causing the variation in phenotype. In Wingert et al.’s study on Phyciodes differences, they found that the genome sequence was different because of the low levels of gene flow and hybridization. Even though these species are capable of hybridization, it shows how these butterflies have been able to maintain their separate genomes and not overly hybridize. In other words, these different species are similar but tend to keep to their own kind when mating.

THOUGHTS: While the pearl crescent does not appear to cross breed with “cousins”, several mammal species do, both naturally and in captivity. There are zonkeys – zebras (subgenus Hippotigris) + donkeys (Equus asinus), camas – camel (genus Camelus) + llama (Lama glama), pizzlies – polar bears (Ursus maritimus) + grizzlies (Ursus arctos horribilis) and others. About half of all plant species on Earth arose through hybridization. Even humans have hybridization early in our history, and many people carry a little Neanderthal DNA. Humanity is different than most other animals as we choose what to differentiate us from each other, even though we are all the same. Act for all. Change will come and it starts with you.

Goliath

June 13, 2026

I came across an article on my MSN browser on a gigantic tadpole discovered in 2018. The Chiricahua Mountains on the Arizona-Mexico border is famous for the Chiricahua leopard frog (Lithobates chiricahuensis). This leopard frog is listed as a federally threatened species that is on the decline due to habitat loss and invasive bullfrogs. A research team was draining a pond when they discovered a massive tadpole in their nets. This was a bullfrog (Lithobates catesbeianus) tadpole that never metamorphosed. Herpetologists are unsure why Goliath was stuck in tadpole limbo but believe it is due to a hormone imbalance, specifically a deficiency of a hormone essential for metamorphosis (thyroxine) combined with an excess of growth hormones. The beast was taken to the Southwestern Research Station before dying in 2019. The tadpole will be preserved by scientists so they can better understand what caused his mysterious condition. Researchers had appropriately named the tadpole Goliath.

When I went online, I found there is a species of frog named the goliath frog (Conraua goliath), also known as the giant slippery frog and the goliath bullfrog, in the family Conrauidae. The goliath frog is the largest living frog. Specimens can reach up to about 18 inches (45 cm) in snout to vent length and 9.9 pounds (4.5 kg) in weight. The species has a relatively small habitat range in Cameroon and Equatorial Guinea. The goliath can live up to 15 years in the wild and up to 21 years in captivity. The primary threat to the goliath frog is hunting, as it is considered a food source in its native range, although other predators are possible. The frog is also threatened by habitat loss and degradation, and they have been extensively exported to zoos and pet trade but have proven shy and nervous in captivity. Although captives may live longer than their wild counterparts, the species has not been bred in captivity.

Goliath, the tadpole, did not undergo the normal metamorphosis where their tails are transformed into legs and development of adult frog features. Despite remaining a tadpole, Goliath continued to grow, making it one of the largest tadpoles ever documented. Its condition is considered extremely rare and provides insight into how hormonal imbalances can affect amphibian development. The case highlights the delicate balance required for normal amphibian growth and metamorphosis. Researchers studied Goliath to understand the effects of endocrine disorders on development. Cases like Goliath also raise questions about environmental impacts like pollution and habitat changes and their effect on the hormonal processes in wildlife. Goliath was preserved by scientists to allow further study of its unique condition. Its story serves as a compelling example of the extraordinary variations that can occur in nature and underscores the importance of monitoring environmental and hormonal factors in amphibian populations.

THOUGHTS: When I found that Goliath had died in 2019, I began to wonder why this popped up on my browser today. A Copilot search gave me three possible answers. It could have been as it was recently linked to a news or science article about unusual wildlife or amphibian biology. Another explanation is a website or blog discussing rare animal cases or environmental science featuring the story. Finally, it might have occurred via a browser ad or redirect or if my browser had been hijacked or exposed to unwanted ads, then it could have shown the page as part of a pop-up or search result. Personally, I think it appeared as I seem to gravitate toward such article in my searches. We are all being tracked for preferences. This can make my searches more effective, if I do not care where this information is shared. Hmm. Act for all. Change will come and it starts with you.

Vulture

June 08, 2026

Researchers at the University of Florida (UF) say invasive Burmese pythons (Python bivittatus) in the Everglades are facing an unexpected new threat. A newly published UF study found that Black vultures and Turkey vultures have become significant predators of python eggs. Motion-activated cameras are capturing the birds digging into nests and consuming eggs while mother pythons temporarily left to bask in the sun. Scientists said the findings could help explain why the rapidly growing python population has not expanded even faster across South Florida despite the reptiles having few natural predators in the region. The study documented vultures destroying nearly half the eggs in monitored nests, raising hopes that native scavengers may be adapting to help naturally suppress the invasive species. Researchers said Burmese pythons have devastated native wildlife populations in the Everglades by preying on mammals, birds and reptiles since becoming established in Florida decades ago. The findings, published in the journal Reptiles & Amphibians, suggest that native wildlife may be adapting to exploiting the destructive, invasive python as a food source.

When I went online, I found vulture refers to a bird of prey that scavenges on carrion. There are 23 extant species of vulture (including condors). Old World vultures include 16 living species native to Europe, Africa, and Asia while New World vultures have 7 species and are restricted to North and South America. Old and New World vultures are not closely related, and their resemblances in similar form or function are not present in the last common ancestor of those groups (convergent evolution). A characteristic of many vultures is a bald, unfeathered head believed to keep the head clean when feeding. North America has three species of vulture. The Turkey Vulture (Cathartes aura) is across the US and South America and is moving north into Canada. The Black Vulture (Coragyps atratus) lives in southeastern US states and into Mexico. California condor (Gymnogyps californianus) is the largest North American land bird. The species became extinct in the wild in 1987 when all remaining wild birds were captured but has been reintroduced to northern Arizona and southern Utah, the coastal mountains of California, and northern Baja California in Mexico.

Researchers stumbled on four vultures eating python eggs in the dense underbrush of the Francis S. Taylor Wildlife Management Area in Broward County, Florida. This is the first documented case of a native Florida bird preying on an invasive python nest. The event occurred in 2023 but was not published until this year. The researchers used a “scout snake” with a radio transmitter to locate the nest and were coming to collect the eggs. The vultures fled the nest when approached and could not be identified as Black or Turkey vultures. The only other documented case of predation on python eggs was in 2021 when a trail camera captured a bobcat eating python eggs in Florida’s Big Cypress National Preserve. There is a precedent for native animals learning to consume invasive species. The Everglades snail kite (Rostrhamus sociabilis) was near extinction when it started eating an invasive snail that is larger than the native snail the birds typically ate, resulting in a rapid microevolution to have larger beaks to be more adept at digging into the larger snail.

THOUGHTS: Growing up in Kansas I saw many a Turkey Vulture, but it was not until we moved to Arkansas that I became aware of the Black Vulture. The two species are often together fighting over carrion or swarming the skies. The Turkey Vulture has a smaller red head and can find carrion with its excellent eyesight or with its sense of smell, while the Black Vulture has a black head and can only find its food visually.

Melissa and I took two long trips this Spring in the RV. We took two trips last Fall to begin RVing. Both trips were less than 100 miles (161 km) and consisted of three days during the middle of the week. We did not pull a vehicle (“toad”) on the first trip and any missed items we went without. We towed the Jeep the second time and were able go into town pick up needed items, including a hose extension for water. We thought we had worked out the kinks and left in February on a 1100-mile (1770 km), 2-1/2 week trip to Florida, but struggled keeping the toad battery charged and had to buy a sewer extension. We thought we solved the battery issue during the week home before we left in March for a 1200-mile (1931 km), 3-week trip to Arizona. We did not. Every time we left the toad attached overnight it still ran down the battery. To top it off, the city water connection valve stripped and we could not connect to the camp hoses. We had planned on stopping at the Grand Canyon, but our main sights were set on my old stomping ground in Utah, so we powered on by.

When I went online, I found a canyon forms by a combination of flowing water, tectonic uplift, and weather acting on the earth’s surface over millions of years. The process of canyon formation often begins with downcutting as rivers and streams carve deep, steep-sided valleys into the earth’s bedrock. The rushing water uses gravel, sand, and rocks it carries like liquid sandpaper to grind away the rock beneath its flow. For massive, deep canyons to form, the ground beneath the river must be pushed upward by shifting tectonic plates (tectonic uplift). This uplift makes the river steeper, increasing its speed and cutting power. Weathering and erosion are the third force acting to create a canyon. Rainwater seeps into cracks in the rock, where it freezes, expands, and breaks the rock apart. Wind, flash floods, and rockslides further widen the canyon walls and wash the debris downstream, preventing the valley from simply becoming a flat slope. All three processes occur simultaneously, and when you add the dimension of time you get a canyon.

It was appropriate that after missing a tour of the Grand Canyon that an article on how it was formed appeared in a USA Today article in our local newspaper several weeks after we returned. A study published April 16 in the journal Science provides one answer to the mystery. According to the study, the Colorado River did not always flow through the canyon and instead began to carve its path around 5.6 million years ago after an ancient lake overflowed. Ryan Crow, co-author and researcher with the US Geological Survey, said scientists have known the river existed 11 million years ago in western Colorado and that it did not exit through the Grand Canyon until after 5.6 million years ago. The mystery was where did it go? Crow said the study tested the idea that the river flowed into the Bidahochi basin in northeastern Arizona. Sand deposits in the ancient lake showed a clear Colorado River signature, indicating the river flowed into the lake. As the lake rose, a spillover became the primary process that established the river’s course through the (emerging) canyon. About two million years later the lake no longer existed and the Colorado River system was fully born.

THOUGHTS: My son and I went to the south rim of the Grand Canyon when he was a child. We did not take the day long hike/mule ride to the bottom but were able to peer into its massive depths. Our takeaway from our two RV trips was that we needed to be more leisurely when we travel. We missed quite a few historic/archeological features because we felt pressed to reach our reserved campground. We assumed if we did not reserve sites, we would not have a place to stay. While that was true for the state parks, every commercial park where we stayed had open spaces. In Europe we took time to “see stuff”, but at home we did not. Do not regret taking time to enjoy the wonder of where you are. Act for all. Change will come and it starts with you.
