Adult Sharp-Shinned Hawks are gray with pale orange underbellies. Juvenile hawks, however, are a streaky brown color.

Sharp-Shinned hawks like to breed and build their nests among forests in lush, thick trees.

They actually make their nests in hideaway places from twigs, bark, and other tree materials.

These hawks have two familiar calls: ‘kik-kik’ and a general high pitched squeal. Sharp-Shinned Hawks in Delaware are known to be athletic, flying through woods and backyards at high speeds.

Goshawks typically breed from April to June, and are sometimes seen during the spring and autumn.

Northern Goshawks are widespread in their range in Delaware and are sometimes difficult to spot.
