Sharp-shinned Hawk vs American Kestrel

In short

The Sharp-shinned Hawk and American Kestrel are both small raptors but differ significantly in structure and behavior. The Sharp-shinned Hawk is a compact accipiter with short, rounded wings and a long tail, while the American Kestrel is a small falcon with pointed wings and a distinctive hovering flight. These differences are key to distinguishing them in the field.

Identification tips

1. Wing Shape: Look for the Sharp-shinned Hawk's rounded wings versus the American Kestrel's pointed wings. 2. Tail Length: Note the longer tail of the Sharp-shinned Hawk, often squared off at the tip, compared to the kestrel's shorter, more rufous tail. 3. Facial Markings: The American Kestrel has distinctive facial markings, including a double mustache stripe, absent in the Sharp-shinned Hawk. 4. Behavior: Observe flight patterns; kestrels often hover, while Sharp-shinned Hawks fly with quick, agile wingbeats. 5. Habitat: Consider the habitat; kestrels are more likely in open areas, while Sharp-shinned Hawks prefer wooded environments.

Size

The Sharp-shinned Hawk is slightly larger and bulkier than the American Kestrel, though both are among the smaller raptors.

Plumage

Sharp-shinned Hawks have a more uniform grayish-brown plumage with a barred tail, whereas American Kestrels display a more colorful plumage with a rufous back and tail, and distinctive facial markings including a double mustache stripe.

Behaviour

Sharp-shinned Hawks are agile fliers that often hunt in wooded areas, using surprise to catch prey. In contrast, American Kestrels are often seen hovering in open areas as they hunt for insects and small vertebrates.

Habitat

Sharp-shinned Hawks prefer forested habitats, especially during migration and breeding. American Kestrels are more commonly found in open areas, including grasslands and urban environments, where they can perch and hunt.
