    The Roadside Hawk (Rupornis magnirostris), also known as Gray-tailed hawk, Large-billed Hawk and tropical Broad-winged Hawk, is the smallest hawk of Central and South America measuring 13.5 – 15.7 inches. 16 subspecies have been recognized.

    Some individuals have brown upperparts and hood, more orange belly barring, and rufous tail bars. Juveniles are browner and drabber. Perched adults are easily distinguished from other small raptors by solid grayish-brown head and breast that contrasts with rufous underparts.


    The Roadside Hawk does not soar, but flies from one perch to another, often shaking tail from side to side. Most hunting is done from a perch, the hawk making a gliding descent toward prey on the ground. The hawk takes a variety of small vertebrate and invertebrate prey.

    Nesting Behaviour

    A pair of roadside hawks seek out an isolated, tall tree, one with a clear view of the land in which to build their nest. Often the pair returns to the same tree year after year. Out of small dry branches, they weave a shallow dish in the fork of 2 branches.

    One or two eggs are incubated for 36 days. Both parents hunt for the food, which consists of squirrels, lizards, frogs, bats, mice, and insects. Chicks are easy prey to snakes, tree-dwelling mammals, raccoons and opossums.

    Distribution & Habitats

    It often occurs along roads, other open habitats and mature forests. Often found perched in a clearing, this hawk is generally tame and easy to approach. This hawk species is very rare stray into southern Texas.

    Throughout its extensive range from Mexico to Southern Argentina, it is common and conspicuous. In some places, it is better known as a riverside hawk, as it is regularly seen from boats when perched up in riverside trees.
