Description

The ferruginous hawk is a large raptor within the Grassland Natural Region of Alberta; inhabiting areas dominated by native prairie. The provincial ferruginous hawk population has been estimated every five years since 1982, except between the years 1993 and 1999. The population estimate is based on the number of active nests detected during each inventory year. During the 2010 inventory, a population estimate of 643 ± 169 breeding pairs of ferruginous hawks was calculated. This population estimate is similar to the 2005 estimate, which implies that the population is relatively stable at low numbers. Overall, Alberta's ferruginous hawk population still remains significantly lower than the 1992, and thus, it is essential to take management actions to assist with the recovery of this species.
