COMMON NAME: MerlinMerlin

SCIENTIFIC NAME: Falco columbarius

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

RANGE:Merlin Chick
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.

Nests are found in forests or scrublands that are broken up by open areas, where the birds hunt. In Minnesota they are generally 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, Minnesota, where up to five pairs have been reported. In 2000, TRC biologist Matt Solensky reported two successful nestings by merlins in Minneapolis.

NESTING:Merlin Chick
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.

Merlins feed primarily on small to medium-sized 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.

As the Minnesota breeding population grows, we see more merlins admitted to the clinic every year, most often with traumatic injuries.

The merlin is not afforded any special status.
