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.

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.

Description

The ferruginous hawk, an endangered species in Alberta, breeds exclusively in the grasslands of North America. Availability of nesting sites has been identified as a key limiting factor of this species. Artificial nests poles (ANPs) were identified as a possible recovery action by the Alberta Ferruginous Hawk Recovery Team, however a number of questions were raised on how effective the installation of ANPs in the past have been in maintaining ferruginous hawks. The Ferruginous Nest Pole Inventory was completed in 2009, and included cataloguing the nest platforms and their state of repair, identifying their use by ferruginous hawks and other species, and evaluating any conflicts that their placement may have created for other species at risk. Of the149 poles evaluated, 45 had active ferruginous hawk nests. A number of issues were identified that may have caused poles not to be active through this inventory. ANP’s may be an appropriate recovery action for ferruginous hawks in areas...

Description

The ferruginous hawk, a migratory bird of prey which occurs exclusively in North America, is listed as Endangered in Alberta. The goal of this recovery plan is to achieve a viable, self-sustaining ferruginous hawk population distributed across suitable habitat in Alberta's Grassland Natural Region through maintenance and/or enhancement of a functional prairie ecosystem. The plan provides background information on the ferruginous hawk, describes the threats facing the species, outlines proposed strategies to address these threats, and presents an action plan that lists priority actions required to maintain and restore the species.

Description

Species such as the ferruginous hawk, which exhibit declining populations, clumped distribution or are spread out over a large geographical area, are especially difficult to determine accurate population estimates for. The ferruginous hawk is a "Threatened" species in Alberta. Inventories for the species were conducted in 1982, 1987, 1992 and 2000 with varying results between surveys and low precision. This prompted reviews of the survey methods and analysis in 2003 and 2005. Recommendations from these reviews were applied in 2005 to a new survey of the ferruginous hawk population and the changes which were implemented substantially increased the confidence in the population estimate. A population estimate of 618 pairs of ferruginous hawks was derived.
