Description

The ferruginous hawk is designated a Threatened species under Alberta's Wildlife Act. Recent declines in the ferruginous hawk population in Alberta prompted an evaluation of the current technique for surveying ferruginous hawks. Recent population estimates have had relatively low precision with confidence intervals ranging from 30-50% of the estimated population. The primary objectives of this paper are to re-evaluate the ferruginous hawk population estimate by stratifying the sample units using the native prairie vegetation baseline inventory data, and to develop a standardised protocol for monitoring population trends of ferruginous hawk in Alberta.
