IDENTIFICATION BASICS

Details that can help identify an owl: 

Ear tufts

Does the owl have ear tufts on the top of its head, or is it round-headed? 

Size

Is the owl relatively large, or close to the size of a duck? Or is it relatively small, closer to the size of a robin? 

Eye and bill color

Are the eyes yellow or orange, or are they dark brown or black? Is the bill dark colored, or light colored? 

Plumage color

What color are the owl's feathers? Does it have any other distinct markings, like spots?

Time of day

Owls are typically nocturnal or crepuscular. However, activity patterns can change seasonally and vary from one individual to another. Generally, more energy is required during the breeding season, which means owls are out hunting for longer periods. 

Hunting behavior

In general, owls hunt in two ways:


Perching and pouncing — usually from a low perch, common among forest owls


Quartering — flying low over the ground, common among open-country owls

Habitat

What is the habitat like where you saw the owl? Is it an open meadow? A wooded park? A thick forest? Near water? Urban or suburban, or a more rural or undeveloped area?

Distribution

Look at a species distribution map in a bird field guide. You can also search online for what owl species are in that area.

Vocalizations

Do you hear a high or low pitched 'hoot'? Is the owl calling with a rhythmic, slower-paced hooting, or a faster-paced single note? Or is the owl yelping, screaming, whistling, or barking?
