Mexican Wolf

November 20, 2024

Toward the back of the front section of my local newspaper was a USA Today article on a reward being offered for information on a dead wolf. The female is protected under the Endangered Species Act and was found northwest of Flagstaff, Arizona, on November 7th. The US Fish and Wildlife Service did not provide a cause of death, but the “mortality was not attributed to agency management actions”. Officials are offering a reward of US$103,500 for information that leads to “the successful prosecution” of the case. The wolf, known officially as F2979 and colloquially as “Hope”, was first GPS collared back in July. The Western Watersheds Project, a non-profit dedicated to protecting western watersheds and wildlife, shared a photo of the wolf in July during a wellness check clearly showing the collar. Cyndi Tuell, director of the project, said,” the shooter had to know she wasn’t a coyote.” The Mexican wolf is one of the most endangered mammals in North America, being driven almost to extinction in the mid-1980’s by hunting, trapping, and poisoning practices.

When I looked online, the Mexican wolf (Canis lupus baileyi), also known as the lobo mexicano or lobo, is a subspecies of gray wolf (Canis lupus) native to eastern and southeastern Arizona and western and southern New Mexico in the US and in fragmented areas of northern Mexico. The wolf originally ranged from eastern Southern California south into Baja California, east through the Sonora and Chihuahua Deserts, and into West Texas. The Mexican wolf is the smallest of North America’s gray wolf subspecies, weighing 50 to 80 pounds (23 to 36 kg) with an average height of 28 to 32 inches (71 to 81 cm) and an average length of 5.5 feet (1.7 m). It is similar to the Great Plains wolf (Canis lupus nubilus), but with a smaller, narrower skull and darker, more variable fur (pelage), which ranges from sandy to yellowish gray with black, brown, and some white highlights. The snout, inner legs, neck and undersides are white, while golden-yellow and beige hues dominate the top of the head and much of the rest of the body. The fur around the chest and neck forms a grayish black collar which flows onto the back where it is generally black all the way to the tail tip. As of 2024, there are at least 257 wild Mexican wolves in the US and 45 in Mexico. Another 380 wolves are in captive breeding programs.

There have been 92 Mexican wolf deaths recorded since 1998. Four occurred in 2012 as a result of illegal shootings. In 2015, a court ordered the US Fish and Wildlife revise the management rules after a survey done on the wolf population of the Mexican wolf in Alpine, Arizona, indicated the recovery of the species is being negatively impacted by poaching. Poaching accounted for 50% of all Mexican wolf mortalities from 2008 to 2019. In an effort to fight the slow recovery, GPS monitoring devices are being used to monitor the wolves. In 2016, 14 Mexican wolves were killed, making it the highest death count of any year since they were reintroduced into the wild in 1998. While two of the deaths were caused by officials trying to collar the animals the rest of the deaths remain under investigation.

THOUGHTS: The Mexican wolf was held in high regard in Pre-Columbian Mexico, considered a symbol of war and the Sun and referred to as Cuetzlachcojotl. The Apache call the Mexican wolf “ba’cho” or “ma’cho”, and there is a “wolf song” passed through oral tradition where the tribe used to summon the wolf’s power before battle. It is estimated up to 16% of the Mexican wolf diet may now include domestic cattle (Bos taurus), especially in locations where the cattle graze and calve year-round as opposed to seasonally. Studies suggest reports of wolf depredation on livestock are sometimes exaggerated or fabricated. That reflects the contrasting attitude as an invasive species (cattle) was introduced by Europeans. Act for all. Change is coming and it starts with you.

Yellow-legged

November 19, 2024

Inside the front section of my local newspaper was a USA Today article on the recovery efforts for a nearly extinct frog. The High Sierra lakes in Yosemite National Park have been biologically upset for over 100 years by the stocking of non-native fish. The rainbow, golden, brown, brook, and cutthroat trout, along with Atlantic salmon and grayling, were originally carried in buckets to these fishless lakes. After World War II, a generation of pilots who were adept in aerial bombing sped up the process in all but 20% of the smallest mountain lakes. While these lakes contained no fish, they were bursting with life. Within a few years of stocking the frog populations that had flourished were gone. The National Park Service ended fish stocking in the 1990’s out of concern for the native species. In 1992, Roland Knapp, a research biologist from the University of California, Santa Barbara, got permission to use gill nets to remove the fish from a small number of lakes. The frogs began to make a comeback, but in the early 2000’s research showed the arrival of amphibian chytrid fungus. The Sierra Nevada yellow-legged frog was added to the endangered species list in 2014.

When I looked online, the Sierra Nevada yellow-legged frog (Rana sierrae), also known as the Sierra Nevada Mountain yellow-legged frog, is a true frog endemic to the Sierra Nevada of California and Nevada in the US. The yellow-legged was formerly considered the southern mountain yellow-legged frog (Rana muscosa) until a 2007 study elevated the more central and northern populations to full species status and restricting the latter to the southern Sierra Nevada and southern California. Both mountain frogs are similar in appearance but are separated by differences in mitochondrial DNA. The yellow-legged grow up to 1.5 to 3.5 inches (3.8 to 8.9 cm) long and females tend to be larger than males. The frogs have brown backs, often with dark spots or bands, and yellow legs and underbellies. Considerable variance exists in species coloration and yellow-legged frogs can also be grey, red, or greenish brown with dark splotches. Tadpoles appear black or brown and require one to four years to fully develop. These frogs hibernate during the winter, staying submerged in the mud and may only be active around three months a year depending on the weather. Studies showed 92.5% of the yellow-legged populations have gone extinct and are estimated to have declined by over 90% over their range. They are considered an endangered and vulnerable species by the IUCN.

In 2006, Yosemite National Park and the Yosemite Conservancy began a project to introduce frogs into lakes without fish. In 2007, a project was started to restore frog habitat by removing non-native fish from remote sites. Once the site is fishless, lakes are inhabited by native species, including the yellow-legged frog. The ecological effects of their loss have been significant as the yellow-legged were a keystone species and important for nutrient and energy cycling in the aquatic and terrestrial ecosystems. A 2016 survey in Yosemite indicated a sevenfold increase in their numbers reported, but recent studies discovered amphibian chytrid fungus is contributing to the decline of the Sierra yellow-legged frog. Chytrid fungus leads to a usually fatal disease (Chytridiomycosis). Chytrid fungus lives on keratin which is found on the external mouthparts of tad poles and the outer skin layer of adults. Fungus growth on adults disrupts the ability to breathe through skin (osmoregulate). The species also suffers from habitat fragmentation as populations have become separated.

THOUGHTS: Stocking fish in the High Sierra’s began as early as the California Gold Rush in 1849. The fishless lakes seemed like a waste to the miners hiking into the backwoods. Stocking fish did provide food, but it nearly destroyed the delicate habitat of the high mountains. While introducing an invasive species may seem like a good idea, it is rarely the case. Life in fragile environments is especially vulnerable. Act for all. Change is coming and it starts with you.

Siamese

November 13, 2024

Today’s MSN browser featured a report on a crocodile thought to be extinct in the wild a generation ago that is making a comeback. The animals are being bred in captivity and reintroduced to their natural habitat. The conservation effort began in 2012 and last June the crocodiles laid 106 eggs and produced 60 hatchlings. There are about 1,000 of the crocodiles in the wild, including 400 in Cambodia. The species was nearly killed off by habitat destruction, poaching, and crossbreeding. Ironically, the hunters who captured, bred, and killed the crocodiles to sell their skins helped them bounce back. These captured crocs are the source of purebred, fertile crocodiles that were pulled from a population of 1.5 million (mostly hybrids) being bred for leather. After the females lay eggs, the eggs are incubated at the Phnom Tamao Wildlife Rescue Centre, allowing the crocodiles to develop before they are brought to a national park in the Cardamom Mountains. According to Pablo Sinovas of Fauna & Flora, only one in 20 crocodiles born in the wild survives, but if they are bred captively and not released until they reach 1 meter in length, “their chances of survival increase exponentially.”

When I looked online, I found the Siamese crocodile (Crocodylus siamensis), also known as the Singapore small-grain and soft-belly crocodile, is a medium-sized freshwater crocodile native to Indonesia (Borneo and possibly Java), Brunei, East Malaysia, Laos, Cambodia, Myanmar, Thailand, and Vietnam. The animal is medium-sized, with a relatively broad, smooth snout and an elevated, bony crest behind each eye. It is generally olive green but can range to a dark green. Immature crocodiles measure 4 to 5 feet (1.2 to 1.5 m) and weigh from 13 to 26 pounds (6 to 12 kg). Adults can grow to a length of 7 to 10 feet (2.1 to 3 m) and weigh from 88 to 265 pounds (40 to 120 kg). Adults have a bite force of 466 to 1,029 pounds per foot (2,073 to 4,577 N). Large males can reach over 13 feet (4 m) and weigh 770 pounds (350 kg). The species is critically endangered and already extinct in many regions.

The Siamese crocodile is critically endangered on the International Union for Conservation of Nature (IUCN) Red List and is listed on Appendix I of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). In Cambodia, Fauna and Flora International and the Government of Cambodia’s Forestry Administration have established the Cambodian Crocodile Conservation Programme for the protection and recovery of Siamese crocodiles. This program works with a network of indigenous villages who are helping to protect key sites such as Veal Veng Marsh (Veal Veng District), the Tatai River (Thmar Bang District), and the Araeng River. The Araeng is thought to have the second largest population of Siamese crocodiles in the world but is being threatened by proposed construction of a massive dam. The Siamese take advantage of the increase in water levels during the Monsoon season (June to November) to move out of the river and onto large lakes and other local bodies of water, returning to their original habitat once water levels receding back to their usual levels. Since 2012, approximately 50 purebred Siamese crocodiles have been released into community-protected areas to reinforce the depleted wild populations.

THOUGHTS: Conservationists are also trying to protect Siamese crocodile’s habitat as 32% of the Cambodia’s tree cover was lost from 2001 to 2023 due to climate change and deforestation. Sean Pang stated, “Policymakers must recognize that addressing both climate and land use change is crucial for protecting the fate of South-east Asia’s trees, and likely for much of the region’s biodiversity.” The world’s natural resources are at peril without a combined effort by government, conservationist, and the local population. Act for all. Change is coming and it starts with you.

House Finch

November 05, 2024

Melissa received a window box bird feeder as a gift from our son and family earlier this year. The feeder has suction cups on the back that allow it to attach directly to the glass. I placed the feeder in the bay window in the breakfast nook that serves as her home office so she can enjoy the bird activity while working. I fill the two sections of the feeder with different seeds to make it more attractive to the small birds willing to approach the window. One side has always had black sunflower seed (Helianthus annuus). I have varied the seed on the other side, but it currently has cracked safflower seed (Carthamus tinctorius). This feeder has become a preference for the eastern bluebirds (Sialia sialis), the sparrows (Genus, Zonotrichia), and purple finches (Haemorhous purpureus) that frequent our back yard. On Sunday I noticed what seemed to be a new species at the feeder. This was similar to the finches I have been watching but somehow seemed different. When I checked my bird ID this turned out to be a house finch.

When I looked online, I found the house finch (Haemorhous mexicanus) is a North American bird in the finch family. The species is native to Mexico and southwestern US but has been introduced to the eastern part of North America and Hawaii and is now found year-round throughout the US and most of Mexico. The house finch is a moderate-sized bird at 5 to 6 inches (12.5 to 15 cm) long, with a wingspan of 8 to 10 inches (20 to 25 cm). Body mass can vary from 9⁄16 to 15⁄16 ounces (16 to 27 g) with an average weight of 3⁄4 ounces (21 g). Adults have a long, square-tipped brown tail and are a brown or dull-brown color across the back with some shading into deep gray on the wing feathers. Breast and belly feathers may be streaked, and the flanks usually are. Most adult males have reddish heads, necks, and shoulders, and the color can extend to the belly and down the back as well. Male coloration varies in intensity with the seasons as it is derived from a diet of berries and fruits. Adult females have brown upperparts and streaked underparts. There are around 40 million house finches across North America, making it the second-most populous finch behind the American goldfinch.

The house finch and purple finch are closely related species and can be hard to identify. The main difference between the two species is the amount of red on the bird and the pattern on the face. They have similar body shapes, but the bill of the purple finch is a bit bigger, more conical, and deeper, while that of the House Finch has a more rounded shape. Both species get along with other small birds except during breeding season when they become protective of their territory. The other big difference comes with habitat. The house finch prefers a wide range of arid, open, and semi-open habitats, and will live in oak-juniper woodlands, open coniferous forests, and shrubby, and desert habitats from sea level to more than 11,000 feet, the house finch avoids dense forest of the purple finch. A small flock of house finch in Long Island, NY, escaped captivity in 1939 and has become the common bird of the eastern US and southern Canada. Their population has grown and expanded to millions of birds that thrive in urban and suburban places, preferring parks and urban settings with conifers and ornamental trees. Their songs are similar, but the purple finch sings a more melodious and “warbling” song, while the house finch incorporates chattering and trilled sounds.

THOUGHTS: Another similarity between the house finch and purple finch is they are both attracted to bird feeders. This explains why I have seen both species (and probably not realized it until now) in our backyard. Neither species is rare, but the house seems more urban and the purple more forest. Nature tells us that when the same species spend enough time separated and/or refusing to interact they grow apart and eventually become distinct. While humans have not yet reached that point as a species, it is a good lesson to be learned. Act for all. Change is coming and it starts with you.

Moo Deng

September 28, 2024

Moo Deng is a pygmy hippopotamus living in Khao Kheow Open Zoo in Si Racha, Chonburi province, Thailand, born on 10 July 2024. Her name was chosen through a public poll with over 20,000 people voting for “Moo Deng”, translating to “bouncy pig”. The zoo posted images of her on its Facebook page and Moo Deng quickly became a fan favorite for her playful and energetic romps. Her popularity led the zoo to sell clothing and other merchandise featuring designs based on her likeness. Other companies produced merchandise, including a cake shop (Vetmon Café) which created a realistic cake shaped like her. Moo Deng’s viral popularity resulted in a doubling of daily visitors in early September. The zoo is in the process of copyrighting and trademarking “Moo Deng the hippo” to raise funds for the zoo and plans to launch a livestream to allow fans to watch Moo Deng over the Internet.

When I looked online, I found Moo Deng is a pygmy hippopotamus (Choeropsis liberiensis) or pygmy hippo, a small hippopotamid native to the forests and swamps of West Africa. The pygmy is one of only two extant species in the family Hippopotamidae, the other being the larger common or Nile hippopotamus (Hippopotamus amphibius). The pygmy hippo was unknown outside West Africa until the 19th century and is a reclusive and nocturnal forest creature difficult to study in the wild. Like the common hippo, the pygmy hippo displays terrestrial adaptations but is semiaquatic and relies on water to keep its skin moist and its body temperature cool. Mating and birth may occur in water or on land. The pygmy is herbivorous and feeds on ferns, broad-leaved plants, grasses, and fruits it finds in the forests. Current pygmy populations are primarily in Liberia, with small groups in Sierra Leone, Guinea, and Ivory Coast. It has been extirpated (eradicated) from Nigeria. Pygmy hippos are primarily threatened by loss of habitat, as forests are logged and converted to farmland. The Pygmy are also vulnerable to poaching, hunting for bushmeat, natural predators, war, and are illegally hunted for food in Liberia. The species breed well in captivity and the vast majority of research is derived from zoo specimens. A 2015 assessment by the International Union for Conservation of Nature estimated that fewer than 2,500 pygmy hippos remain in the wild.

As a viral sensation Moo Deng has prompted a makeup trend popular with beauty influencers. Moo Deng makeup is in line with what beauty enthusiasts look for, super dewy skin and lots of blush. The trend is perfect for fall as the skin will be hydrated and glass-like as the drier months approach. The trend started with influencers trying to recreate her iconic look by achieving the baby pygmy’s glass-like skin with the prettiest shade of blush. Before applying makeup, you need to ensure the base is nice and dewy to capture the baby hippo’s glistening skin. The trend incorporates lots of grey hues to represent Moo Deng’s skin color. An element common among influencers’ is the heavily flushed cheeks. Any blush shade will do, as long as it has a great color payoff. Grey eyeshadow or lip gloss, followed by a particular shade of blush create the final makeup look.

THOUGHTS: While Moo Deng may create viral views, sales, and makeup, she is at risk. Some visitors harassed Moo Deng by splashing her with water and throwing objects to wake her up, forcing the zoo to install security cameras around her enclosure. The zoo also implemented a 5-minute time limit for visitors to accommodate the high volume of visitors. While most marvel at the wonder of nature, there are others who find pleasure in destruction. Whether it is throwing objects at Moo Deng or toppling 100,000 year old rock formations the seconds of fame being sought are not worth the cost. “Influence” comes with responsibility. Act for all. Change is coming and it starts with you.

Leopard Darters

September 25, 2024

Last week the Arkansas Game and Fish Commission (AFGC) released 80 leopard darters into the wild with the help of state and federal partners along with Conservation Fisheries LLC, a private hatchery specializing in propagating rare and threatened species. According to Chance Garrett, fish ecologist for the AGFC, this release is the first of two scheduled for the Cossatot River in western Arkansas this year and is the first historical reintroduction effort of leopard darters anywhere. The fish were grown from broodstock taken from the Mountain Fork River which flows from Arkansas into Oklahoma. Another 250 fish are planned for release in early October. Garrett said, “They originally thought it was only found in Oklahoma, but some populations were found in the Rolling Fork and Cossatot after its listing. Those two populations are thought to no longer exist, so this effort to re-establish them is extremely important.” This is the second year of the project, but the first year saw a low survival rate as the hatchery and were added to the broodstock rather than being released. The leopard darters measured and an inch or two (2.5 to 5 cm) at stocking size and were transported from the hatchery to their destination in one day.

When I looked online, I found leopard darters (Percina pantherina) are a species of freshwater ray-finned fish, from the subfamily Etheostomatinae. The family (Percidae) also contains the perches (Genus, Perca), ruffes (Gymnocephalus cernua), and pikeperches (Genus, Sander). The species is native to the US and is only be found in the Little River drainage in Oklahoma and Arkansas. A typical habitat is medium to large streams with rubble and boulder substrate. The leopard darter feeds on small invertebrates on the riverbed and spawns in March and April. Adults rarely exceed 3 inches (8 cm) in length and have 11 to 14 large, dark spots on their sides, which contrast against a light background that ranges from pale olive on the back to yellowish olive on the underside. The back of the fish has numerous saddles and bars. The leopard darter is threatened by impoundment, habitat loss, and runoff from agricultural activity. It has never been a common species and has been listed as a threatened species in the US since 1978.

Transporting and releasing the leopard darter was a full day affair. They left the Conservation Fisheries hatchery in Knoxville, Tennessee in the morning, were met by AGFC personnel in Memphis, and driven to the other side of other side of Arkansas by 6:30 p.m. that evening. Once at the river, the fish had to be tempered to adjust to the river water. They arrived in bags which were floated to slowly acclimate to the temperature of the river water. Then some river water was let into the bags to help them adjust slowly to the chemistry of that location. Finally, they are ready for release. The staff scanned the release pool the next day and found many of the fish had dispersed. Garrett said. “Hopefully we’ll see them in future survey efforts . . . Ultimately our goal is to see some spawning activity in spring.” The leopard darters represent one of the longest-standing members of the Endangered Species Act.

THOUGHTS: Leopard darters typically live less than two years, but individuals older than three years have been found. Introduction of these 320 fish (total) could reintroduce a viable population into the Cossatot River, but the fragile species still faces the loss of habitat due to construction of reservoirs and population isolation, along with agricultural and industrial activity, that drove them to decline in the first place. Species reintroduction and preservation takes the combined efforts of government agencies, business, and individual landowners to be effective. While it may take a village to raise a child, it takes concerned communities to preserve endangered species. Act for all. Change is coming and it starts with you.
