Lesser Nighthawk

Family

Description

8-9" (20-23 cm). Similar to Common Nighthawk but smaller, with white wing patch (buff in female) nearer tip of wing (visible in flight). Both sexes have buffy cast to underparts. Male's throat white; female's buffy. Whereas Common Nighthawk hunts and calls from high up, Lesser Nighthawk flies low and utters no loud aerial calls.

Voice

A soft, sustained, tremolo whirring; very difficult to locate.

Listen

song

Habitat

Open dry scrublands; desert valleys; prairies and pastures.

Range

Breeds from central California, Arizona, and parts of Nevada, Utah, New Mexico, and Texas southward. Winters in tropics.

Discussion

The Lesser is more nocturnal than the Common Nighthawk and hunts its insect prey by flying low above the canopy of trees or the brush and grass of open plains. During courtship flight display, the male pursues the female close to the ground, flashing his white throat as he calls.

Nesting

2 spotted, light gray eggs on open ground.
