Existing Protection or Other Status Designations

In Canada, B. regalis is listed as being of ‘Special Concern’ by COSEWIC (last assessment in 1995). The species is currently listed under Schedule 3 of the Canadian Species at Risk Act (Statutes of Canada 2002). The Ferruginous Hawk is listed as Endangered under the Alberta Wildlife Act and as Threatened under the Manitoba Endangered Species Act. The species is not listed in Saskatchewan.

According to NatureServe, the global status of B. regalis is G4 (apparently secure). However, out of 17 states and three provinces where Ferruginous Hawks occur they are considered by NatureServe to be secure in only two states and one province (Figure 7). This species is listed as critically imperilled in one Canadian province (British Columbia, S1B – extremely rare throughout its range in the province with typically 5 or fewer occurrences or very few remaining individuals) and one state. It is imperilled in one province (Manitoba S2B – rare throughout its range in the province [6 to 20 occurrences or few remaining individuals] and may be vulnerable to extirpation due to rarity or other factors] and eight states; and vulnerable in one province (Alberta; S3B - ) and five states. It is listed as secure in only one province (Saskatchewan S4B) and two states, and was not assessed in one state.
