Swainson's Hawk(Buteo swainsoni)
 
Status in the Checklist Area - (8) Accidental
     
 
Information

A slender hawk in the same family as our common Red-tailed Hawk. MIgratory, breeds in the Interior's grassland habitats and winters in South America. In addition to small rodents, also eats large insects. Encounters in our area are basically limited to spring and fall migration and birds are rarely seen more than one day as they appear to move through fairly quickly.

Similar species:
Light phase Swainson's Hawks are relatively distinct from other hawks, but more care needs to be taken with the intermediate and dark phased birds as they can appear similar to Red-tailed Hawks (which can vary significantly in plumage). Wing shape and colour is a good clue. Swainson's Hawk has long and pointed wings with dark tips and trailing edge. Red-tailed Hawks are more broadly tipped and lack the strong dark trailing edge of the wing. See photos below.

February 11, 2008 Highway 11, Abbotsford K. Stewart 2008a A sight record of an intermediate phase adult. While this would be unusually early for a Swainson's Hawk to be this far north, the bird's features were well described. Consequent searches by other birders did not turn up the bird reported.
