Burrowing owl survey : 1994 report

Metadata Updated: December 12, 2017

Report of burrowing owl nesting activity in the Central Region of Colorado in 1994, produced by the Colorado Division of Wildlife. There is little long term data on burrowing owl population trends in Colorado. The U.S. Fish and Wildlife Service (USFWS) Breeding Bird survey data suggest a decline from 1966 to 1989 in the Colorado burrowing owl population and an increase from 1980 to 1989. However, both of these trends are not statistically significant and the validity of this data for long term trend analysis has been questioned (Barker 1991). While population declines over large areas have not been confirmed in Colorado, local population declines and potential causes have been identified. Loss of breeding habitat through control of prairie dogs, cultivation of grasslands and urbanization are suspected of causing population declines. In addition, pesticides may cause declines by reducing insect prey species, direct mortality of the birds, or reduced reproductive success. This study contains information about burrowing owl populations nested at the Denver International Airport (DIA) mitigation site and on the Rocky Mountain Arsenal National Wildlife Refuge. The purpose of this survey was to inventory breeding burrowing owl populations in the Central Region.
