The chuck-will's-widow (Antrostomus carolinensis) is a nocturnal

Ontario, Canada and Cape Cod, Massachusetts) near swamps, rocky uplands, and pine woods. It migrates to the West Indies, Central America, and northwestern South America
.

Taxonomy

The chuck-will's-widow was

monotypic: no subspecies are recognised.[6]

The common English name "chuck-will's-widow " is an onomatopoeia from the bird's song.[9] Alternative names include "chuckwuts-widow" and "chip-fell-out-of-a-oak".[10]

This bird is sometimes confused with the better-known whippoorwill (Antrostomus vociferus),[11] because of their similar calls and unusual names. Though rather closely related, they are two distinct species.

Description

The chuck-will's-widow has a short bill and a long tail typical of the nightjars. It has mottled brownish underparts, a buff throat, reddish-brown feathers lined with black, and brown and white patterning on head and chest. Males have patches of white on their outer tail feathers. It is the largest nightjar in North America. In length, it ranges from 28 to 33 cm (11 to 13 in). The wingspan can range from 58 to 66 cm (23 to 26 in). The body mass of the species is from 66 to 188 g (2.3 to 6.6 oz).[12] Among standard measurements, the wing chord is 20.1 to 22.5 cm (7.9 to 8.9 in), the tail is 13 to 15.1 cm (5.1 to 5.9 in), the bill is 1.1 to 1.4 cm (0.43 to 0.55 in) and the tarsus is 1.5 to 1.9 cm (0.59 to 0.75 in).[13]

The repetitive song is often heard at night. It consists of a series of calls with a vibrating middle note between two shorter notes, not much shifting in pitch.[14] It is slower, lower-pitched and less piercing than the song of the whip-poor-will.

Behavior and ecology

Diet

It eats primarily insects, particularly those active at night such as moths, beetles, and winged ants. It will also eat small birds and bats, swallowing them whole.[15][16]

Breeding

The eggs are laid on patches of dead leaves on the ground. They are pink with spots of brown and lavender and are incubated by the female.
