Todd E Katzner

My research interests focus on wildlife conservation ecology and the interaction between wildlife and the role of wildlife in natural systems. 

Much of my work is built around utilization of novel technologies and approaches to wildlife ecology. I was part of a team that developed the first non-invasive monitoring scheme for any avian species, I was involved in development of novel high-frequency GPS-GSM telemetry systems for tracking migratory birds, and I developed a network of camera traps to monitor abundance and distribution of terrestrial avian scavengers across eastern North America. Much of my recent funding is focused on evaluating the potential impacts of renewable energy development on conservation-dependent birds.

Pinyon-juniper and sagebrush on Juniper Mountain, NV

Pinyon-Juniper Disturbance Effects on Wildlife

Researchers from the U.S. Geological Survey are reviewing, summarizing, and analyzing what is currently known about changes happening in pinyon-juniper ecosystems in the western U.S. in response to tree removal treatments. Although tree removal can help restore sagebrush ecosystems, these treatments also impact wildlife, wildfire fuels, and invasive plants. This project will help identify key...

Interaction Between Alternative Energy Development and Raptors

Energy production has become essential for modern society. At the same time, this process can have negative effects on wildlife and ecosystems. It is in the best interest of society and the environment to understand these effects and to manage and mitigate for them. Our team focuses on measuring how energy development influences birds of prey and learning how to minimize impacts.

Conservation Ecology and Monitoring of Raptors

Raptors, or birds of prey, are often used to indicate the state of an ecosystem, and monitoring their populations can help us to understand ecosystem processes. Raptors are particularly good animals for monitoring because they are big and therefore charismatic and easy to observe. Whether we’re monitoring nesting biology and reproductive output, counting individuals on roads, or setting up trail...

Bird Movement and Migration

Migration is an amazing annual event. Every year billions of animals – birds, mammals, insects, and fish – make long-distance journeys from breeding grounds to wintering grounds. Most northern hemisphere birds migrate southward, but there are many other ways that birds move seasonally. If we want to protect birds that take these long distance journeys, we need to understand why they move, why they...

Coexistence in a multispecies assemblage of eagles in central Asia Coexistence in a multispecies assemblage of eagles in central Asia

We evaluated factors that permit species coexistence in an exceptional assemblage of similar raptor species at the Naurzum Zapovednik (a national nature reserve) in north-central Kazakhstan. White-tailed Sea-Eagle (Haliaeetus albicilla), Imperial Eagle (Aquila heliaca), Golden Eagle (A. chrysaetos), and Steppe Eagle (A. nipalensis) all breed at the Zapovednik. Steppe Eagle use of nesting...

Bird Movement and Migration

Bird Movement and Migration

Migration is an amazing annual event. Every year billions of animals – birds, mammals, insects, and fish – make long-distance journeys from breeding grounds to wintering grounds. Most northern hemisphere birds migrate southward, but there are many other ways that birds move seasonally. If we want to protect birds that take these long distance journeys, we need to understand why they move, why they...

Coexistence in a multispecies assemblage of eagles in central Asia Coexistence in a multispecies assemblage of eagles in central Asia

We evaluated factors that permit species coexistence in an exceptional assemblage of similar raptor species at the Naurzum Zapovednik (a national nature reserve) in north-central Kazakhstan. White-tailed Sea-Eagle (Haliaeetus albicilla), Imperial Eagle (Aquila heliaca), Golden Eagle (A. chrysaetos), and Steppe Eagle (A. nipalensis) all breed at the Zapovednik. Steppe Eagle use of nesting...
