The 2015 ferruginous hawk (Buteo regalis) inventory and population analysis

Description

The ferruginous hawk is a large raptor within the Grassland Natural Region of Alberta; inhabiting areas dominated by native prairie. It is currently listed as an Endangered species under Albert’s Wildlife Act. The provincial ferruginous hawk population has been estimated every five years since 1982, except between the years 1993 and 1999. This report presents the findings of the 2015 survey. The 2015 population inventory showed a slight, but insignificant increase. Further research is required to confirm the cause for the slight increase. Although, initial analysis suggests it is related to a fluctuation of their primary prey species as a result of dry conditions of the previous year. Overall, Alberta’s Ferruginous Hawk population remains significantly lower than the 1992 estimate, therefore, it remains essential for management actions to assist in the recovery of the species.
