The Draper Natural History Museum is conducting some exciting research on bats and birds of the Greater Yellowstone Ecosystem (GYE). Find out more below about these projects—the Absaroka Bat Census and the Pinyon Jay Project.
The Absaroka Bat Census began in 2022 and aims to study bat diversity, seasonality, and distribution in the GYE. Data from this research provides managers with important info on bat occupancy and habitat use patterns in the region.
The Pinyon Jay Project, established in 2024, aims to characterize the distribution, habitat use, and movement of Pinyon Jays in Wyoming’s Bighorn Basin relative to Greater Sage-Grouse.
The Absaroka Bat Census (ABC) project aims to study bat diversity, activity, and distribution in the Greater Yellowstone Ecosystem (GYE). By deploying passive acoustic sensors, we seek to provide baseline data on bat presence in high-elevation habitats. These data will provide wildlife managers with important information on bat occupancy and habitat use patterns in our region. We deployed acoustic sensors using two primary methods.
In the first method, we sampled a series of sites along an elevational gradient for a minimum of 4 consecutive nights per site. This method allows us to investigate elevational limits and habitat preferences of different bat species. The second method uses a continuous, long-term monitoring approach, with detectors maintained at the same consistent locations for 4–5 months throughout the summer and fall. Using this method, we can determine how bat occupancy and use of a site changes over time. Both methods allow us to ask and answer different questions. The project is a 3-year effort, beginning in 2022 and set to finish in 2024. Analysis of data is expected to be completed in 2025–26. We will share photographs, project updates, and publications as they become available.
The Wyoming Game and Fish Department (WGFD) lists 11 of the state’s 19 bat species as “species of greatest conservation need.” For many of these species, basic information on their distribution, abundance, and habitat requirements is lacking. This absence of data includes our specific area of focus—bat presence and use of alpine landscapes in North America.
To our knowledge, our project is one of the most spatially comprehensive surveys of bats in the Greater Yellowstone Ecosystem and we have documented more instances of bat activity in alpine habitat than previous efforts.
Bats across North America face multiple threats, such as habitat loss, wind energy development, and the fungal disease white-nose syndrome. Bats are indicators of the diversity and health of the state’s ecosystems. Despite bats comprising 15 percent of all mammal species in Wyoming, little is known about their diversity and distribution in the state. We hope the data we have collected are used by state and federal wildlife agencies to inform conservation and management plans for bats in northwestern Wyoming and southern Montana.
Katy Goodwin is a wildlife biologist and data analyst with more than 15 years of experience in biological research and monitoring. She currently works as a federal agency biologist and volunteers her time on the Absaroka Bat Census. From 2017–2023, Katy coordinated a large-scale bat acoustic monitoring program across nine national parks in the Great Lakes region, field tested different ultrasonic microphone models, and evaluated agreement among different acoustic data processing software programs. Although Katy’s most recent focus is studying bats, she has also spent many days in the field observing and collecting data on wetlands, songbirds, amphibians, and mustelids. Katy’s favorite aspect of the Draper research project is exploring the mountain ranges of the GYE and getting to know the remarkable creatures that inhabit them. She’s particularly intrigued by the Long-Legged Myotis, a small bat with extra fur on its wings which helps it thrive in cold temperatures.
Dr. Jason Riggio is a Postdoctoral Scholar in the Museum of Wildlife and Fish Biology in the Department of Wildlife, Fish and Conservation Biology at the University of California, Davis. His research focuses on applied solutions to wildlife and landscape conservation challenges. Jason is particularly driven to address human impacts on biodiversity at the intersection of species distributions and global change, but also appreciates that the best maps at any scale are often informed by local surveys. As a postdoc, he is conducting a large-scale biodiversity monitoring project of California Department of Water Resources riparian forest and wetland restoration sites across the Sacramento-San Joaquin Delta. Jason is also working on research projects in Wyoming surveying bat populations in alpine areas of the Absaroka Mountains and Pinyon Jays in the Bighorn Basin, and in East and Southern Africa developing methods to map continental-scale and multi-species landscape connectivity and wildlife corridors.
Jordan Harrison is an avian biologist from Bozeman, Montana. Over his career he has worked for various non-profit and private organizations on two continents and across the western United States. His current work is especially focused on bald and golden eagle diet, productivity, and resource selection. He became interested in bats through alpine mountaineering in the northern Rockies, where he would often see bats flying on high peaks during early alpine-starts or late finishes when climbing. The intersection of biological research and time spent in the alpine environments of the GYE drew him to the research and partnership opportunities presented by the Draper Natural History Museum and the Absaroka Bat Census.
Corey Anco is the Willis McDonald, IV Curator of Natural Science at the Draper Museum. Corey is inspired by the ability of natural history museums to aid in the discovery and sharing of scientific information among people of all ages and learning abilities. Corey’s research activities are conducted in tandem with the needs of state and federal natural resource managers.
The Absaroka Bat Census (ABC) program was undertaken to fill gaps in knowledge about bat occupancy in alpine and montane environments of the Absaroka Mountains. The best part of Corey’s job is translating the scientific results into engaging and immersive interactives and content, which can be found throughout the Draper. He hopes to incorporate findings from the ABC program into a future nocturnal exhibit.

The ABC’s first year, 2022, saw the deployment of bat detectors (acoustic sensors) at a total of 22 survey sites within the 3 study areas. Although one detector failed due to a damaged microphone cable, detectors at the remaining 21 sites successfully recorded for a total of 130 survey nights. Sampling yielded a total of 166,951 audio files! Find out more about the 2022 season, watch this Lunchtime Expedition by Corey Anco.
Spatial coverage expanded in 2023 with the addition of study sites throughout the Absarokas in Wyoming and extending into Montana. At the end of Project Year 2, the team has cumulatively sampled 8 drainages, deployed 47 sensors, and collected more than 550 survey nights worth of data. To date, 18 volunteers contributed to this project resulting in approximately 850 miles hiked and more than 250,000 feet of elevation climbed!

Over the last 50 years, the Pinyon Jay (Gymnorhinus cyanocephalus) has experienced an 85 percent population decline. Little has been done to address the alarming decline due to a lack of certainty about its cause.
The Draper Natural History Museum, in partnership with the Bureau of Land Management, the Museum of Wildlife and Fish Biology at the University of California, Davis, Northwest College, and the U.S. Fish and Wildlife Service, are studying the causes of this decline by characterizing habitat use by Pinyon Jays across limber pine-juniper woodlands and comparing Pinyon Jay movement data with existing datasets for Greater Sage-Grouse (Centrocercus urophasianus), a species currently being managed by the Wyoming Game and Fish Department.
The Pinyon Jay is named for its close association with Piñon Pines. However, Piñon Pines are absent from northwest Wyoming and the Bighorn Basin. Instead, in the Basin, Pinyon Jays are suspected to primarily feed on the large, wingless seeds of Limber Pines (Pinus flexilis), though reliance on Limber Pine seeds is not well documented in the scientific literature. In fact, Pinyon Jay populations in Wyoming have never been formally studied. Furthermore, Pinyon Jays occupy habitat adjacent to and potentially overlapping with another declining bird species of conservation concern: the Greater Sage-Grouse (Centrocercus urophasianus).
When conifers, such as Limber Pine, begin to grow in the sagebrush-steppe, they are removed if expansion encroaches into Sage-Grouse habitat. This widely accepted management practice may enhance Sage-Grouse habitat but have the unintended negative impact of reducing Pinyon Jay habitat. Separating areas where Sage-Grouse habitat may be improved from areas where Pinyon Jay habitat may benefit from conservation is a win-win opportunity for both species and a focus of this research.
