Merlin - Falco columbariusAlso known as the "Pigeon Hawk", the Merlin is a small, fast falcon which catches its main prey (small birds) in flight.   Merlins have become adapted to living in urban areas and may overwinter in cities, taking advantage of the steady supply of House Sparrows and Rock Doves (pigeons) that urban centers provide.

Habitat: Prefers mixed habitat of trees and adjacent open spaces for breeding.  May winter in nearly any habitat.

Diet: Mostly small birds, also small mammals, insects, and reptiles.

Behavior: Primarily hunts from a perch, flying out to capture prey when it is sighted.  Also will fly low over the ground in order to surprise prey. 

Nesting: May and June

Breeding Map: Breeding bird survey map

Song: Rapid shrill ki-ki-ki-ki. 

Migration: Merlins summer in Canada and the northern U.S. Rockies, and winter through the western half of the country and along the East Coast.

Similar Species: American Kestrel

Conservation Status: Possibly in decline due to effects of pesticides.
