Ecology & Life History | |||||||||||
General Description: | A falcon with long pointed wings, a dark crown and nape, and a dark wedge extending below the eye; forehead is pale in immature, which are mainly brownish above rather than black or gray as in adults (NGS 1983). | ||||||||||
Subspecies Comments: | Three subspecies of peregrines occur in British Columbia: F.p. anatum and F.p. pealei breeds in the province; F.p. tundrius is a long distance migrant that probably passes through the province (Campbell et al. 1990; Cannings 1998; Cooper and Beauchesne 2003b). The Anatum (F.p. anatum) Peregrine Falcon occurs in the southern interior, and although taxonomy still is uncertain, it is thought to be the subspecies that inhabits the Fraser River valley and Gulf Islands (Cooper and Beauchesne 2003b). | ||||||||||
Identification Comments: | Anatum Peregrines are slightly smaller than Peale's, and somewhat paler, but not as pale as the Tundra Peregrine Falcon. Variations within each of the subspecies tends to be clinal, with some overlap between the subspecies (White et al. 2002). | ||||||||||
Global Reproduction Comments: | See files for FALCO PEREGRINUS. | ||||||||||
Provincial Reproduction Comments: | Productivity for coastal Anatum Peregrines in British Columbia is relatively high, as 2-4 fledglings are the norm in recent years for most pairs (D. Doyle, pers. comm. 2004). Recovery of this subspecies on the coast is aided by immigration from elsewhere, for example, there are two known breeding Anatum Peregrines in coastal British Columbia that were banded as nestlings in the San Juan Islands, Washington (D. Doyle, pers. comm. 2004). Prey species for Anatum Peregrine Falcons in the Okanagan region continue to have high levels of organochlorines. Should the species return to the Okanagan region (either naturally or through re-introduction efforts), existing contamination levels may affect reproductive success (Elliott et al. 2005). | ||||||||||
Global Ecology Comments: | See files for FALCO PEREGRINUS. | ||||||||||
Provincial Ecology Comments: | Availability of suitable nest sites is often considered the limiting factor for Peregrine Falcons, when habitat approaches saturation. However, in the southern interior of British Columbia, historic aeries remain vacant, indicating that some other factor is not permitting the recovery of the species in this area (Cooper and Beauchesne 2003b). | ||||||||||

Global Migration Comments: | See files for FALCO PEREGRINUS. | ||||||||||
Provincial Mobility & Migration Comments: | Anatum Peregrine Falcons move south for the winter with immature birds showing up in the Fraser River delta by August (Campbell et al. 1990). In the Okanagan valley, when birds bred there, these breeding birds would leave the valley from early September through October (Cannings et al. 1987). | ||||||||||

Global Habitat Comments: | See files for FALCO PEREGRINUS. | ||||||||||
Provincial Habitat Comments: | Anatum Peregrine Falcons typically nest on rock cliffs above lakes or river valleys where abundant prey is nearby. Interior populations are typically associated with wetland habitats that support a sufficient prey base. In the Okanagan valley, aeries have been reported as low as 6 m above a lake and high on cliffs that towered >260 m above the valley floor (Cannings et al. 1987). In the Lower Mainland, nests are on rock cliffs well back but above the Fraser River. In the Gulf Islands, nests are found on seaside cliffs (Cooper and Beauchesne 2003b). | ||||||||||

Global Food Habits Comments: | See files for FALCO PEREGRINUS. | ||||||||||
Provincial Food Habits Comments: | Concentrated populations of shorebirds, waterfowl, pigeons and songbirds are important prey; other prey may include bats, rodents and insects (Rowell 2002). Peregrines require an ample supply of suitable prey species in areas that permit aerial hunting (Beebe 1974). | ||||||||||
