RRC Interim Director Jim Belthoff Honored with Raptor Research Foundation Award
Dr. Jim Belthoff, the RRC’s Interim Director and a professor of biological sciences at Boise State University, was honored by the Raptor Research Foundation in December 2020 with the Fran and Frederick Hamerstrom Award. This award is presented to “an individual who has contributed significantly to the understanding of raptor ecology and natural history” after being nominated by peers in raptor biology. Read all about Jim’s thoughts on receiving the award, his work and education, and his favorite raptor in this Boise State News article.
Multi-Year Raptor Inventory and Survey Project
National Conservation Area and Orchard Combat Training Center
Dr. Jim Belthoff (Principal Investigator) and Research Associate Steve Alsup, MS
The Orchard Combat Training Center (OCTC) lies within the Morley Nelson Snake River Birds of Prey National Conservation Area (NCA). Idaho Army National Guard training activities on the OCTC are managed under a Memorandum of Understanding with the Bureau of Land Management (BLM), the management agency for the NCA. As such, the OCTC training lands must be managed in accordance with the Department of Defense’s and the BLM’s (Department of Interior) environmental regulations. Specifically, BLM’s Manual 6840 establishes policy for management of species listed or proposed for listing pursuant to the Endangered Species Act and Bureau sensitive species which are found on BLM-administered lands. In order to comply with these regulations, the Idaho Army National Guard is proactively surveying for these species and their associated habitat in order to maintain their compliance with the PL 103-64 and established management guidelines.
Raptors that nest in the canyon of the Morley Nelson Snake River Birds of Prey National Conservation Area (NCA) depend heavily on the OCTC for foraging and transiting between foraging areas. This use has been documented in extensive telemetry studies, surveys, and observations from the 1980s to the present. Although we know historical densities of raptors nesting in the canyon, raptor densities and reproductive performance in the area had not been evaluated since 2003. Therefore, there is little understanding of the current abundance and density of raptors that rely on military lands for key aspects of their life history. Therefore, an important need to survey these populations exists to ensure the continued compatibility of military activity with the protection of natural resources and heritage. This ongoing project looks at the current abundance and distribution of raptors associated with the NCA and scientifically compares the demography of birds in modern surveys with those from earlier surveys conducted on the same lands.
In addition, there is an alarming trend associated with the amount of illegal shooting of federally protected migratory birds in and around the OCTC. Not only does this illegal shooting kill protected wildlife, but it also decreases reproductive performance and degrades the long-term natural heritage of these military lands. The purpose of this project is to provide information on the scope and scale of the problem of the illegal shooting of migratory birds within and around military lands. Specifically, the project will provide information on the seasonal frequency with which illegal shooting of migratory birds occurs, the estimated spatial distribution of potential hotspots, shooting density maps within those hotspots, and the species that are targeted.

Study Finds Illegal Killing of Protected Idaho Wildlife More Widespread than Previously Known
(2020) A new study has, for the first time, quantified the problem of the illegal killing of several species of non-game birds and snakes in two conservation areas in southwestern Idaho: the Morley Nelson Snake River Birds of Prey National Conservation Area and the Long-billed Curlew Habitat Area of Critical Environmental Concern. The journal Conservation Science and Practice has published the study by 18 authors representing Boise State University’s Raptor Research Center, Intermountain Bird Observatory, and Department of Biological Sciences; the U.S. Geological Survey; the Idaho Army National Guard; Saint Mary’s University of Minnesota; and Conservation Science Global, Inc., with cooperating partners the U.S. Fish and Wildlife Service, the Bureau of Land Management, Idaho Department of Fish and Game, and the Idaho Power Corporation. Boise State University’s article by Anna Webb describes the study in broad strokes.
Researchers Investigate Climate Change Effects on American Kestrel
New Research Shows Owls’ Ability to Hunt Impaired by Noise
(2016) The study by Jesse Barber, assistant professor of biology at Boise State University, and Tate Mason, Boise State alumnus and education coordinator for The Peregrine Fund, is the first to examine the impact of noise on a predatory bird. Their findings were published in the journal Biological Conservation under the title “Anthropogenic noise impairs owl hunting behavior.”
These Adorable Owls Will Not Kill You With Plague
(2015) Raptor Biology professor Dr. Jim Belthoff’s research on burrowing owls was featured in Wired magazine. The story talks about fleas that infest the birds and their burrows, which can carry the bacteria that causes plague. Belthoff’s work shows that the owls appear to be immune to the ailment, which presents the opportunity to test if the owls could protect humans from plague. Read the full story (and watch a video).
