Swainson’s Hawks in Plumas County
10,000 Birds
OCTOBER 22, 2014
The last time I visited Portola was in the summer of 2011 when the Swainson’s Hawks ( Buteo swainsoni ) were nesting there. Each autumn, nearly the entire breeding population of the Swainson’s Hawk migrates from the temperate zone of North America to wintering areas in South America. Click on photos for full sized images.
