Murie Audubon General Meeting and Program on April 11th, 2024

Murie Audubon Presents

It’s ?tting that during our spring bird migration, Will Robinson will be our guest speaker to inform us about the migration of the giant honey bees (Apis dorsata) in Thailand. And just like the ungulates and birds more familiar to us here, the honey bees travel the same route each year, following the food sources as they become available across the land. What started as a sabbatical for Robinson, has turned into four trips, in 2009, 2010, 2016, and 2023. On the latest trip that ended in December of 2023, Robinson and his wife, Maria Katherman, were working with the World Wildlife Fund to protect the migratory bee stopover site he identi?ed on their ?rst trip. On his original trip, Robinson soon found that what appeared to be large hives were in fact large clumps of bees hanging from trees as “bivouacs” while they rested during migration. And just as Wyoming has learned the importance of preserving migratory routes for mule deer, he feels the same approach should be applied to bees. Similar to the experience many of us have had observing the Sandhill Cranes or large ?ocks of geese, Robinson shared that “It’s absolutely incredible to have an entire group of 50,000 bees ?y right over your head. The adrenaline rush is like nothing I’ve ever experienced. It is soul stirring.” Robinson’s presentations are always excellent, and we hope that you may join us for this free talk on April 11, 2024 at 7 p.m., at the Izaak Walton Clubhouse, at 4205 Fort Caspar Road.

Join us for a special presentation by Alan Corey as he debunks misconceptions about lighting and how to light your path more efficiently. The Light Pollution” program will be held on Thursday, May 11 at 7 PM at the Izaak Walton Clubhouse at the Fort Caspar Campground, 4205 Fort Caspar Road. Corey is the president of the Great Plains Astronomical Community. We live in a world of perpetual artificial light and it is causing big problems with human health, wildlife, and the environment. We call this artificial light “light pollution” and it is widely seen as a result of industrial civilization, but it doesn’t have to be. Artificial light is wreaking havoc on the natural body rhythms of both humans and wildlife and it affects the physiological processes in nearly every life-form on Earth. This discussion will focus on what light pollution is, what form it takes, where it comes from, and what we can do to lessen our impact. This program is free and open to the public.

Edness Kimball Wilkins State Park (known by most simply as EKW) located near one of the most populous cities in Wyoming, is very popular among outdoor enthusiasts. Audubon members flock there for birding opportunities, as well as a good place for an outdoor walk. Carlo Migliaccio is the superintendent at Edness Kimball Wilkins State Park and will be our guest speaker this month. Users of EKW have no doubt seen changes in the last few years, from the removal of Russian Olive trees to the staging of pre-fab overnight cabins. Carlo reports that they are in the process of completing several projects started last year, and have a few others in the queue, which they are hoping to complete before December of this year. Plans are to complete several conservation-oriented projects, including renovations and replanting in Betty’s Garden, replanting along the river, and the construction of a pollinator garden near the Mountain View shelter. There are also several recreational projects in the works, including the completion and opening of the overnight cabin facilities, archery range, and installation of lifejacket stands along the pond. Carlo’s presentation will address the details of these projects, along with a brief history of the park, and a discussion of longer term plans for conservation and improvement.
This month we return to an in-person meeting and we will gather at the usual location at the Izaak Walton Clubhouse to participate. To take part, come to the Murie Audubon free talk on March 9, 2023, at 7 p.m., at the Izaak Walton Clubhouse, at 4205 Fort Caspar Road.

In this presentation on February 9, we learn how to create wildlife-friendly gardens that help combat the loss of open spaces. Learn how to create green corridors that link your wildscape to larger natural areas by providing habitat for wildlife. Jamie Weiss, Habitat Hero Coordinator for Audubon Rockies, will be presenting this program. Along with her B.S. in marine biology and chemistry from University of North Carolina Wilmington, Jamie is a certified interpretive guide through the National Association for Interpretation. Jamie previously worked at Boyd Lake State Park and the Georgia Aquarium as an educational interpreter, raising awareness of conservation.
When not working, she is often leading an active lifestyle trying to keep up with her Border Collie puppy and Golden Retriever. She enjoys hiking, camping, snowboarding, and long-distance running. Jamie will be presenting remotely from Colorado, we will gather at the usual location at
the Izaak Walton Clubhouse to participate. To take part, come to the Murie Audubon free talk on February 9, 2023, at 7 p.m., at the Izaak Walton Clubhouse, at 4205 Fort Caspar Road.

The Swift Fox, a tiny, lesser known, but valuable part of the grassland and desert ecosystems of Wyoming, will be the subject of our January 12, 2023 program. Weighing only five pounds on verage, with a black tipped tail, the Swift Fox is the smallest fox species in North America and the smallest member of the canid family. Historically found across western North America, these foxes were thought to occupy the eastern part of Wyoming and can still be found there in small numbers. Like many predators, Swift Fox numbers in the U.S. and Canada saw a dramatic decline about the turn of the 20th century due to anti-predator campaigns and habitat changes. Efforts have been made in recent decades to preserve remaining Swift Fox populations, and their work seems to be paying off. Wildlife officials in Wyoming are beginning to see an increase in Swift Fox populations, with more frequent sightings across the state. In fact, they’ve been expanding their range into higher-elevation areas like Big Piney and Pinedale. Researchers and Wildlife officials are currently using various methods to get an estimate of Swift Fox numbers, as well as some genetics from scat, to get an idea of how many individuals seem to be showing up within a given area. Research ecologists are working to trap and reintroduce Swift Foxes from Wyoming to the Fort Belknap Indian Reservation in Montana. Foxes were trapped in Natrona County this past summer. Heather O’ Brien, Nongame Mammal Biologist for the Wyoming Game and Fish Department from Casper, will be our guest speaker.

Andrea is the statewide Nongame Bird Biologist for the Wyoming Game and Fish Department’s Nongame Program based in Lander, and will be presenting the meeting. She is collaborating on this project with colleague Dr. Courtney Conway from the University of Idaho and his research partners from the U.S., Canada, and Mexico. Recent developments in solar-powered GPS technology in the form of smaller transmitters are helping researchers collect data on the elusive seasonal migration and winter ranges of Burrowing Owls that nest in Wyoming during the summer months. In the past few years, researchers have placed satellite transmitters on Burrowing Owls in western states. Unfortunately, many of those have died or their transmitters have stopped sending locations. Owls outfitted with the new transmitters from Wyoming, along with other owls from western states and Canadian provinces, will add new data and hopefully new understating about these mysterious little birds. The Burrowing Owl is classified as a Species of Greatest Conservation Need in Wyoming, making this full annual cycle conservation project extremely important. Andrea will discuss the need for this work, project objectives and methods, and results of Burrowing Owl migration. Please join us on Thursday, May 12, 2022 at 7 pm at the Izaak Walton Clubhouse at 4205 Fort Caspar Road for this program. As always, the program is free and open to the public! Hope to see you there! -Bruce Walgren

Murie Audubon General Meeting & Program, April 14

This month we will learn about how torrent ducks (Merganetta armata) live at high altitudes in the Andes of South America. This presentation will help us understand these riverine specialist ducks, and the methodology used to capture them alive. We will also learn about their history: when and how torrent ducks occupied the Andes, their behaviors (diving, feeding, and reproduction), their population abundance, and their orphological and physiological adaptations to the extreme conditions that they live in, such as high elevation, low temperatures, and hypoxia. Our guest speaker, Dr. Alza-Leon, is an ecologist, working in evolutionary biology. He works as a full-time instructor at Casper College and as an associated researcher to the Centro de Ornitología y Biodiversidad in Peru. He spent more than twenty years working in the field in Peru, and other countries in South America and in the Antarctic Peninsula. He began his career as an undergraduate in 1995, working in different research and monitoring projects. Later, in 2012, he started in the Ph.D. program at the University of Alaska at Fairbanks, and finished at the University of Miami, Florida. During that time, he moved to Casper in 2017 to start his family, and worked as a zoology adjunct instructor for the University of Wyoming at Casper.

Please join us on Thursday, April 14, at 7 PM at the Izaak Walton Clubhouse, 4205 Fort Caspar Road, for this program. As always, the program is free and open to the public!
