The coyote (Canis latrans) expanded its geographic range considerably on the heels of wolf (Canis lupus) extirpation from most of the United States. The earliest records of wild coyotes in New York State stem from the 1920s, but the species became widespread and common only in the last several decades. This novel addition to the northeastern ecosystem has generated tremendous public interest, and the two most commonly asked questions have been: “How many coyotes are there?” and “What is their potential impact on deer populations? “

Project Title: Population status and foraging ecology of the coyote

This research addresses those questions by deploying high-tech collars allowing us to track coyotes to their kills and a suite of both high-tech (noninvasive genetic tools) and low-tech (vocalization surveys) approaches to quantify their numbers.
