Aplomado Falcon - Falco femoralis

The Aplomado Falcon is a widespread raptor with a range that covers much of South America, Central America, and southern Mexico.  They used to commonly range much further north, with nesting occurring in the southwestern United States.  However, by 1960, the species was evidently extirpated from its United States range, as well as large parts of northern and central Mexico.  The last known nesting in the U.S. was in New Mexico in the 1950s, until the successful nesting of a pair in 2002.  Significant efforts have been made to reintroduce the species in southern Texas, and the species has been increasingly seen in New Mexico as well in recent years. 

Habitat

They can be found in open grassland habitats with scattered shrubs and trees, as well as open marshy areas.  They will also use large forest clearings.

Diet

Small birds make up a large portion of the diet.  They also often feed on large insects, and will sometimes take small rodents, small lizards and snakes, and bats.

Behavior

Most prey is taken on the wing.  Aplomado Falcons can often been seen capturing insects from mid-air, and consuming them in flight.  Mated birds often hunt cooperatively.

Nesting

Nesting usually occurs in stick nests built by other birds.  Both the male and female will incubate the eggs (typically 2 or 3), and both parents will help to raise the young.

Song

A sharp kek-kek-kek alarm call is given when disturbed or when a bird senses danger.

Migration

Aplomado Falcons are permanent residents in most of their range, but birds do make altitudinal migrations, with birds that summer at higher elevations moving to lower elevations in the winter.

Status

Populations of the Aplomado Falcon are considered stable, and the species has a widespread distribution.  They are considered a species of "Least Concern" by the IUCN.  They have, however, been extirpated from parts of their former range, including large portions of northern and central Mexico, and the southwestern U.S.
