Environment / Birds

Among the bird world’s most skilful flyers, Cooper’s Hawks (Accipiter cooperii) are common woodland hawks that tear through cluttered tree canopies in high speed pursuit of other birds. You’re most likely to see one prowling above a forest edge or field using just a few stiff wingbeats followed by a glide. They are forest and woodland birds, but leafy suburbs seem nearly as good. These lanky hawks are a regular sight in parks, quiet neighborhoods, over fields, at backyard feeders, and even along busy streets if there are trees around. Cooper’s Hawks mainly eat birds. Small birds are safer around Cooper’s Hawks than medium-sized birds: studies list European Starling, Mourning Dove, and Rock Pigeon as common target along with American Robin, jays, Northern Flicker, quail, pheasant, grouse, and chickens.

This data suggests that cities with higher Birds per Observer Hour contain higher numbers of hawks. As a woodland bird, Cooper’s Hawks require woodland areas in which to nest, and adequate food resources in the immediate area. Therefore, it is expected that higher numbers of Cooper’s Hawks indicate larger or more extensive green spaces within the respective urban/suburban settings.

Not all cities had data available for the full 25 year timeframe. In these cases, the available timeframe was used to plot trends. Please review the report for full city-by-city, year-to-year data.
