Merlin

SCIENTIFIC NAME: Falco columbarius

Slightly larger than kestrels, merlins appear uniformly dark in the field. Males are brighter than females, with slatey blue wings and back, dark head, and dullfacial markings. The underside is rufous with dark streaks. The tail is slatey gray with a dark terminal band. Females are uniformly brown with light, brown streaked undersides. Immatures resemble the female.

RANGE:

Merlins are found worldwide, breeding in the northern latitudes and migrating south into Mexico and South America, the Mediterranean, the Middle East, and southern China.

HABITAT:

Nests are found in forests or scrublands which are broken up by open areas in which to hunt. In Minnesota they are generaly found in the northern forested part of the state. Urban nesting merlins have started appearing in the prairie provinces of Canada, most notably in Edmonton and Saskatoon. In recent years, merlins started nesting in Duluth, Minn., where up to five pairs have been reported. In 2000, TRC biologist Matt Solensky reported two successful nestings by merlins in Minneapolis.

NESTING:

Like other falcons, merlins do not build their own nests, but instead use the old stick nests of crows or magpies. Up to five eggs may be laid and incubated by the female. The young remain together after fledging and may migrate south together.

FEEDING HABITS:

Merlins feed primarily on small to medium-size birds, but will take insects, rodents, and small lizards. They have been known to take birds as large as pigeons but more often they take small passerines or shorebirds weighing less than 50 grams.
