BREEDING BIRD SURVEY REGRESSION MODELS FOR THE BEAR RIVER WATERSHED CONSERVATION AREA

Utilizing breeding bird survey data, regression models were developed for Sage Thrasher and American Avocet in the Bear River Watershed Conservation Area for the years 2000 and 1997-2010, respectively. The Sage Thrasher model employed a negative binomial regression approach, while the American Avocet model utilized logistic regression. Landscape variables within 1200m and 800m radii, respectively, of each survey site were considered.
