Partula

March 28, 2025

This morning’s MSN browser caught my eye with an article on a creature that has managed to return from extinction. The International Union for Conservation of Nature (IUCN) Red List of Threatened Species has reclassified a peanut sized snail as critically endangered after being previously declared extinct in the wild, according to a release from the Zoological Society of London (ZSL). The snail’s comeback is credited to a decades-long conservation program led by ZSL and its global partners. Paul Pearce-Kelly, leader of the conservation program, said in a news release, “This is a landmark moment for Partula tohiveana and for decades of international conservation work. Seeing a species return from the brink after years of collaborative effort is exactly why we do what we do.” The press release states that the reclassification follows the discovery of adult Partula snails born in the wild.

When I looked online, I found Partula tohiveana is one of several species with the common name Moorean viviparous tree snail. The species is an air-breathing tropical land snail in the family Partulidae endemic to highlands on Moorea, French Polynesia. The species was reintroduced into the wild in 2024 and by September “born in the wild” snails were observed for the first time in 40 years, meaning the species is officially considered re-established. While the snail is still critically endangered, it had been extinct in the wild since the 1980’s. The snail is the first invertebrate species to be successfully re-established following an Extinct in the Wild IUCN status. ZSL started breeding these snails in the 1980’s after the invasive carnivorous rosy wolf snail (Euglandina rosea) began to threaten the Partula tohiveana’s wild population. The snails were bred and cared for under carefully controlled conditions and were then marked with UV reflective paint prior to their release back into their forest habitats. The 2024 reintroduction saw the release of about 6,000 snails from 10 species and sub-species of Partula snails raised at zoos worldwide.

Ali Reynolds, Senior Keeper, Lower Vertebrates & Invertebrates at the Marwell Wildlife Zoo, said: “It was so heartening when I heard the news of tohiveana being downlisted, it makes all our efforts worthwhile, and shows what a difference zoos can make.” Reynolds has a tattoo on her arm with a picture of a snail along with words, “never give up”. She went on to say the more you learn about Partula, the more fascinating they become. The snails show a high level of speciation, and a single species can evolve in very small specific areas, at times even living in only one valley. They are unusual amongst snails, as they do not lay eggs, but give birth to a single live young. Their name comes from Partula, the Roman goddess of birth. “Given the cause of their decline is entirely manmade, we have a responsibly to try to make things right, and this shows that is possible!”

THOUGHTS: One of the global partners that aided the reintroduction of Partula was the Sedgwick County Zoo in Wichita, Kansas. My parents lived there and always had a season pass to the zoo, so when we held reunions, we would all go. This was usually in August and turned out to be the hottest day of the year (100+F/37.7+C). Zoos have always been a subject of interest and debate. Some say they play a crucial role in conserving endangered species and educating the public. Others say they represent captivity for profit and do more harm than good. Zoos do support conservation through breeding and donations that are critical for groups working in areas trying to preserve wildlife. A critical argument for zoos is that people need to see animals to care about their protection and most urban populations will likely never get the opportunity to experience these animals in the wild. Direct encounters with animals encourage people to adopt more eco-friendly behaviors and feel more invested in conservation efforts. Longer life (with ethical treatment) is a tradeoff for freedom. As with humans, not all feel the cost is worth it. Act for all. Change is coming and it starts with you.

Holla Bend

January 27, 2025

The intense cold (highs below freezing) that has stricken most of the south began to lessen over the weekend and Melissa thought it a good time to get out of the house with the kids for a drive. While the motivation was to “just go”, we also wanted to see a birding site. The Sequoya Wildlife Refuge is only about 90 minutes west, but we have not had much luck finding birds in the winter. Lake Fort Smith is an hour north and has good fishing in the cove, but we have never caught much from the shore. I put in a little work while Melissa searched for a new birding site. What she found was about 2 hours away near where she spent her college years. This sounded like a possibility (and promised a trip to her favorite burger joint). We packed up the kids, got gas and aired up the tires that had been deflated by the cold, and took off for Holla Bend National Wildlife Refuge.

When I looked online, I found Holla Bend National Wildlife Refuge is a 7,055-acre (28.6 km²) site located 5 miles (8 km) south-east of Dardanelle, Arkansas. The refuge is bounded on one side by the Arkansas River and on its others by an oxbow lake that was formed in 1954 by the Army Corps of Engineers during efforts to straighten the river navigation channel. The resulting island was transferred to the US Department of the Interior in 1957 for a wildlife refuge. The refuge provides habitat for migratory waterfowl, indigenous endangered species, other resident wildlife, and offers interpretation and recreation to the public. The area is a year-round sanctuary for the 236 species of birds, tree frogs, and the American alligator. Migratory fowl following the Central and Mississippi flyways stay in the refuge during the winter months, including 14 species of ducks and 4 kinds of geese, with as many as 100,000 there at once. Winter migratory neotropical songbirds use the refuge as a rest stop during their long journey to and from Central and South America and during the spring and summer migratory birds use the refuge for breeding and nesting. I anticipated birds.

Last year I purchased an Interagency Lifetime Pass from the US National Park Service so we cruised past the Holla Bend information center without stopping. We turned around realizing we did not know where we were going without a flyer. As we got into the refuge, we saw large flocks of American Robin (Turdus migratorius) on the road between the trees and European starling (Sturnus vulgaris) passing among the harvested grain fields. Along the oxbow we found a flock of mallards (Anas platyrhynchos) and a flock of ring-billed gull (Larus delawarensis) along the river. The best find however, was totally unexpected. We stopped to admire a herd of 20 does and fawns racing across the far end of a harvested field. Then I noticed what I thought was a group of black vultures (Coragyps atratus) about 300 yards (274 m) out. When I focused my camera, I realized this was a flock of wild turkey (Meleagris gallopavo) feeding in the field. It turned out to be a great day. And we topped it with a great burger.

Thoughts: When we stopped at the Holla Bend information office a sign listed the daily hours along with the caveat of “Closed when we are not here”. They were not there. The Wildlife Refuge System is the US’s largest network of lands and waters dedicated to wildlife conservation, but it is facing a staffing crisis. The Refuge System has lost over 800 permanent positions since fiscal year 2011, resulting in a 27% loss in capacity. No national wildlife refuge is fully staffed, and more than half have zero staff on-site. Much of the system is unprotected due to the lack of law enforcement officers. This shortage impacts critical volunteers by a lack of staff supervision or infrastructure. We need to invest in this system and prioritize staffing to ensure the future of this network and the wildlife it protects. Act for all. Change is coming and it starts with you.

Birds 2024

January 04, 2025

I am a little later than usual, but it is again time to recap my annual birder list. Once more I saw a number of red-tailed hawks (Buteo jamaicensis) on the power lines going to and from town but this year I was unable to actually get a picture, so they were not added to my count. I was unable to take my usual trip to the wildlife area this year and so missed out on any of the birds I might have seen there. The end of year presence on my feeders was good as the cold weather brought the small Passerines (sparrows and finches), although the larger birds (cardinals and jays) were mostly absent. I cleaned out the bluebird (Sialia sialis) house last week. One of the squirrels who frequent the feeders has taken to gnawing on the entrance, so I opened it to check if everything was ok. It was fine but I cleaned the nest and debris in preparation for the next nesting season. BTW: for those who read last week’s blog (Gaggle) a group of squirrels is called a “dray” or a “scurry”.

All that said leads up to the “great reveal” concerning my birder totals for 2024. You may recall I recorded 26 species in my first year (2020). I got off to a great start in 2021 with 29 species by the end of January and a total of 52 species for the year. During 2022 the sightings were slower, with 44 different species, not counting the six European sightings (50 total?). During 2023 I recorded my lowest number of sightings since my first year, with only 30 species. During 2024 the numbers rose slightly to 39 documented species. Building a fence in the side yard helped as the kids no longer play near the feeders and the birds feel free to come and go more frequently. Still, early morning and early evening are the best times to watch. We also added three new feeders that attach to the glass on the bay window next to where Melissa works. This allows her to watch as the American gold finch (Spinus tristis) and Dark-eyed junco (Junco hyemalis) as they battle for feeding rights.

As I pulled onto the entrance road to the lake to take the kids for a walk yesterday, I caught sight of a large bird perched in the trees. I drove by as the bird turned and flashed the unmistakable white head of a bald eagle (Haliaeetus leucocephalus). I slowed and then pulled over as soon as I (no shoulders). I walked back the 1/4 mile (400m) scanning the trees and hoping to be able to get a photo for my birding list. Unfortunately, the eagle had moved on and was now out of sight. When we began our walk out onto the first spit of land, I heard the call of a red-bellied woodpecker (Melanerpes carolinus). I scanned the trees along the road and caught sight of the bird high among the branches. I pulled out my phone to take a photo but again, by that time the bird was gone. That made two birds I usually only see a couple of times a year and I had missed documenting them both. These were part of the many birds I have seen but not photographed over my last five years of birding. The official Cornell Lab of Ornithology bird list guide does not require documentation with a photo to count as a sighting, although that has been my criteria. Perhaps I should rethink.

THOUGHTS: I acquired several new feeders (now 13, plus 9 hummingbird feeders) during 2024. Melissa asked about the cost as she watched me buying seeds and filling the feeders on a daily basis. I tend to buy seeds in bulk, and I only have to restock two or three times a year. Watching the birds (and squirrels) gives us both pleasure. Like my garden and Melissa’s succulents, the expense to feed the birds is well spent. Be sure to mark your calendars for the Great Backyard Bird Count 2025 (February 14 to February 17, 2025). As I mentioned last year, birds are the (literal) canary in the mine shaft (earth) when it comes to gauging the health of our ecosystems. Act for all. Change is coming and it starts with you.

Gaggle

December 30, 2024

The kids were overwhelmed as we took our walk at the lake last week. They had been intrigued in the past by the occasional greater egret (Ardea alba) or great blue heron (Ardea herodias) that spend time in the shallows at the end of the two spits we walk. The kids will stop and even strain on their leash trying to get a better look at these large solitary birds. They were not prepared for the mass of birds we encountered on this occasion. The herons had flown away as the kids approached, but the Canada geese (Branta canadensis) stood their ground. Both Zena and Loki hesitated in the face of this loud and raucous group of birds. It was not until the kids composed themselves and began to move forward that the group decided they wanted no part of these two large dogs (Canis familiaris). This gaggle of geese took flight and moved to the safety of the water.

When I looked online, I found a gaggle of geese occurred in English print in Julia Berners book, “The Book of Hawking, Hunting and Blasing of Arms” in 1486. Geese are called a “gaggle” because together they are noisy and rowdy. Little is known of Berners, and much of what is known cannot be verified with certainty, but she is thought to be the earliest female author writing in the English language. Based on her last name, scholars suggest that she was either the daughter of the courtier Sir James Berners or wife to the lord of the manor of Julians Barnes, and she was high-born and well-educated. Since she was most likely brought up at court, she would have hunted and fished with the other fashionable court ladies. It is generally believed that she entered the monastic life and became the prioress of Sopwell Nunnery near St Albans. Berners seemed to retain her love of hawking, hunting and fishing, and her passion for field sports, leading her to write her treatise on hunting and others. These treatises are some of the earliest extant writings of their kind and include remarks on the virtues of environmental conservation and on etiquette for field sports. These concepts would not become commonly accepted for hundreds of years after the publication of these treatises. She is also remembered as one of the first authors (of either sex) to write on angling.

A gaggle is just one of the 165 collective nouns (a “naming word for groups of things) for groups Berners defines in her publication. A group of owls (Order: Strigiformes) is called a parliament, possibly attributed to the idea that owls are considered intelligent and wise. A group of wildebeests (Genus: Connochaetes) is called a confusion. This could be due to the huge numbers of animals that in the annual Great Migration and the resulting confusion and noise that happens when the animals migrate. A group of lemurs (Superfamily: Lemuroidea) is called a conspiracy. Lemurs are social animals and live in communities of around 10 to 25 members who often work together (conspire) to outwit predators using a technique called “mobbing”. A group of hippopotamuses is called a bloat. Hippos live in groups of 10 to 20 females and one male, and bloat may refer to their large, bloated bellies. Finally, a group of wild cats is called a destruction. Feral cats can be territorial and fight to protect their territory, and when a group of feral cats get together, they can become destructive.

THOUGHTS: Canada geese thrived around the golf courses I played in Salt Lake City and would form into a large gaggle around the water hazards. The geese were generally docile as they sat on the lawn or swam in the ponds. The problem came when you hit your ball in their midst, when they cackled and blustered a warning. One even decided my ball was her egg and made an aggressive defense. Animals form groups for protection and defend their territory against predators. Humans use the same tactic and form resistance movements against tyrants or marauders. Like a gaggle of geese, we are stronger together. Act for all. Change is coming and it starts with you.

Beards

November 27, 2024

As we approach Turkey Day, also known as Thanksgiving in the US, there have been a rash of stories on my browser about these interesting birds. These include the recent tradition of the Presidential Pardon. The first official presidential turkey pardon was given by George H.W. Bush in 1989, but reports credit many presidents with the tradition. Abraham Lincoln’s son took a liking to the turkey destined for Christmas dinner and the bird was spared. Harry Truman liked his bird so much he had the first presidential photo op, but that bird was not so lucky and was later served as a meal. Two days ago, President Biden pardoned Peach and Blossom. These domesticated turkeys weighed an impressive 40 and 41 pounds (18.1 and 18.6 kg) respectively. Another story was offered by the National Audubon Society and provided 10 Fun Facts About the Wild Turkey. The most interesting of these facts concerned the bundle of feathers sprouting from their chest is known as turkey beards, and it gets longer as the bird ages.

When I looked online, Audubon also offered an in-depth discussion on turkey beards. Turkey beards are plumes of dark brown or black feathers, more hair-like than a typical feather, that protrude from the bird’s chest. “If you had it in your hand, it has the consistency of a miniature horsetail,” says Gary Norman, a retired gamebird biologist at Virginia Department of Game and Inland Fisheries. While all adult male turkeys (toms) have beards, nearly 10% of hens also have one, although it is a smaller and wispier version. Male turkey beards are thought to be used as another tool for mate selection, but it is unknown why some female birds have them. Kelsey Sullivan, a gamebird specialist with the Maine Department of Inland Fisheries and Wildlife, says the beards can “indicate dominance and health”. Turkey beards start sprouting when youngsters are around five months old and continue to grow at a rate of nearly 5 inches (12.7 cm) a year throughout a bird’s life allowing the biologists a rough estimation of the bird’s age. While a one-year-old beards may measure only a few inches older males can have beards over 10 inches (25 cm). The longest beard length recorded on the National Turkey Wildlife Federation website is 11.75 inches (29.2 cm). Some toms even grow 2 or 3 (and even up to 13) separate beards. In the rare occasion where multiple beards are grown most are just short, wispy feathers with a single dominant cluster.

Turkeys can lose their beards several ways. Turkey beard rot is caused by vitamin deficiency and may result in the beards shearing off. Longer beards can snap from the heavy weight of snow and ice that collects on them during winter. Fraying from being dragged on the ground is also an issue. Terrain is another factor that influences beard length, and turkeys inhabiting rocky terrain may have shorter beards than those foraging across flat, sandy ground. The abundance of bearded hens varies by region and is perhaps affected by previous conservation efforts to recover Wild Turkeys. In the mid-1900’s, wildlife biologists trapped turkeys and moved them across state boundaries to restore severely depleted turkey populations due to hunting and habitat loss. Wild Turkeys have sharply rebounded and now inhabit every US state except Alaska. Wild turkey populations peaked at 7 million birds by the early 2000’s.

THOUGHTS: There are only two species of Wild Turkey; the North American (Meleagris gallopavo) and the Ocellated Turkey (Meleagris ocellata) in Central America. The domestic turkey (Meleagris gallopavo domesticus) shares their cousin’s trait by having beards, neither sex of the ocellated turkey have beards. As for the two pardoned turkeys, they will live out the remainder of their life at Farmamerica, a 360-acre agricultural interpretive center in Waseca, Minnesota. 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.
