Murie Audubon General Meeting and Program on February 8th, 2024

Dr. Bryan Shuman (Ph.D. and Sc.M. in Geological Sciences, Brown University), Professor and Wyoming Excellence Chair in Geology and Geophysics at the University of Wyoming (UW) will present a program on Wyoming’s climate. Shuman has taught at UW since 2007 and uses geological evidence to examine how past climate changes affected water and ecosystems. A central theme of his research is reconstructing the temperature, precipitation, and vegetation history of North America since the last ice age based on evidence from lake sediments. The work uses fossils, physical sedimentology, geophysics and geochemical techniques to determine the full spectrum of natural climate variation, evaluate climate model projections about the past, gain insight into how water and ecosystems respond to climate change, and provide context for the archaeological record. Recent projects have examined the histories of wildfire and the snow-pack in the Rocky Mountains over past millennia to anticipate climate impacts on society and landscapes today. Shuman has written over 120 peer-reviewed scientific publications on related topics. He has also built upon this research background to co-lead the 2021 Greater Yellowstone Climate Assessment.

Come hear about Dr. Shuman’s research at the Murie Audubon free talk on February 8th,
2024 at 7 p.m., at the Izaak Walton Clubhouse, at 4205 Fort Caspar Road.

Murie Audubon General Meeting & Program, 9 November, 2023

Murie Audubon Presents – What’s up at the Tate?

Our November program will be all about the Tate Geological Museum at Casper College. J. P. Cavigelli, Collections Manager / Field Operations & Prep Lab Manager at the Tate will be our guest speaker. JP will talk about the exciting projects that the Tate Museum has been working on since Covid, more or less. While Dee the Mammoth and Lee Rex are the Tate’s superstars, there are so many other character actors and extras involved in the show. Dinosaurs and, oh, so much more from Wyoming’s varied geological past. Ichthyosaurs, crocodiles, mammals, and maybe even a bird or two. JP has talked to us on several previous occasions, and for those who don’t know him, he came to Casper in 2004 Before coming to the Tate, he worked on and off in paleontology for 14 years, doing ?eld work as well as a two year post as the collections manager for the University of Wyoming Department of Geology and Geophysics. He has had the good fortune of having been invited to join international paleontological expeditions to Mongolia, Niger (twice), Tanzania (twice), northern Alaska, and North Dakota. The public and Audubon members are invited to come to the Murie Audubon free talk on November 9, 2023 at 7 p.m., at the Izaak Walton Clubhouse, at 4205 Fort Caspar Road.

J. P Cavigelli and Bruce Walgren


We’d love to get as many people as possible to attend this fun-filled event. We’d like to think of this as a membership drive, to encourage people to find out more about Murie Audubon, and potentially join. There will be cash prizes awarded to the winner of each round. There may even be an extra special bird identification bingo round.

Please, invite all your friends (as long as they are 21 or older)! We’d love to have a packed house!

Murie Audubon General Meeting & Program, 11 May, 2023


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.

Murie Audubon General Meeting & Program, 13 April, 2023

The Casper Mountain Science Program will present an overview of the program on April 13th, 2023. Eric Reish, the program director of CMSP (and possibly some staff), will share an overview of the program and its history going back to the start in 2007. Included will be a summary of who the program reaches, the number of students it has served, and some of the impacts on our community and beyond. We will look over some sample curriculum and we will have a “hands-on” activity for those that choose to participate with us. We will share photos of our local students enjoying themselves while learning the Wyoming State Standards. To take part, come to the Murie Audubon free talk on April 13, 2023, at 7 p.m., at the Izaak Walton Clubhouse, at 4205 Fort Caspar Road.

Project Goal

Each February, for four days, the world comes together for the love of birds. Over these four days we invite people to spend time in their favorite places watching and counting as many birds as they can find and reporting them to us. These observations help scientists better understand global bird populations before one of their annual migrations.

Murie Audubon General Meeting & Program, November 10

Joanne Theobald will be our guest speaker on November 10 at 7 PM for her program entitled, “Turkey Vultures: Friend or Foe?” Theobald will share her collection of photographs and videos, as well as information about turkey vulture traits, habits, and folklore. Theobald, formerly director of counselling at Casper College, is a participant in University of Wyoming’s Wyoming Naturalist Program and has been volunteering at Edness Kimball Wilkins Park as well as helping with the Rocky Mountain Amphibian Survey this year. She says, “My real passion is turkey vultures. For the past six years, a group of about forty has roosted in the spruce trees behind my house, and I’ve become obsessed with them. People have many negative misconceptions about them, and I’d like to educate others about these amazing creatures.” Theobald maintains an Instagram page about turkey vultures, @vulturesinmybackyard. If you wish to learn more about Turkey Vultures, come to the Murie Audubon free talk on November 10, 2022, at 7 PM, at the Izaak Walton Clubhouse, at 4205 Fort Caspar Road.

Murie Audubon General Meeting & Program, MARCH 10

Speaker Ben Robb, currently a research ecologist for the U.S. Geological Survey’s Fort Collins Science Center, studied the impacts of Interstate 80 on pronghorn migration and crucial habitat for his master’s degree at the University of Wyoming. His study predicts the best corridors to restore pronghorn movement. Robb’s research was supported by the Wyoming Migration Initiative at the Wyoming Cooperative Fish and Wildlife Research Unit at UW. His research focuses on wildlife found along the periphery of human development, and how this research can be applied to try and improve access to habitats. Audubon members and the public are welcome to a free talk March 10, 7 p.m., at the Izaak Walton Clubhouse at 4205 Fort Caspar Road concerning pronghorn migration and habitat and the barrier I-80 presents.

The speaker will be joining us remotely via Zoom. Participants can either join us at the Clubhouse or register in advance for this meeting:

After registering, you will receive a confirmation email containing information about joining the meeting.

Murie Audubon General Meeting & Program, 10 FEB


This month we will learn about the North Platte River in, around, and through Casper. We will learn about the history of the river from pioneer
times, through dam building, and oil and other pollutants that ended up in the river, to where it is today. Matt Hahn, a fisheries biologist for the Wyoming Game and Fish Department will be our guest speaker. A twenty year veteran with the Wyoming Game and Fish Department, Matt
began his career in Green River, then in Laramie, before coming to Casper in 2006.

Matt will bring us up to date on status and health, as well as the management challenges of the North Platte River. Please join us on Thursday, February 10, 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
