Sharp-Shinned Hawks are very small birds–actually, the males are the smallest hawks in the entire country.

Female Sharp-Shinned Hawks, though, are about a third larger than the males. The adult hawks of this species have gray feathers with orange underparts.

Immatures, however, are brown with white underparts. The sharp-shinned hawk is a common migrant, but a rare summer resident in Illinois.

Spring migrants arrive in March, nesting in northern coniferous areas. They prefer dense trees to breed in larger forested areas.

Sharp-Shinned Hawks can be commonly spotted in early spring, and are recognized for their shrill cries and panicked ‘kik’ sounds.

Adults are a pastel color with orange underparts. Immature hawks have brown and streaky feathers. These hawks are steadily increasing, and were moved from Illinois’ endangered species list.

With the rapid influx in population, Cooper’s Hawks are very territorial when it comes to their homes and families. They prefer to make their homes in Illinois’ abundant forests, mountainous areas, and acres of open spaces.

Cooper’s Hawks nest in tree trunks or in tall trees on their branches. These hawks breed in March and migrate in early autumn where they can be seen in flight throughout early November.

Interestingly, they have adapted to urban and suburban environments where you can see them more commonly than in previous years.

Red-Shouldered Hawks like nesting in forests in the trunks of cone-bearing trees by open waters.
