Caprimulgidae – Nightjars & Nighthawks
The Caprimulgidae or nightjars are medium-sized nocturnal or crepuscular family characterised by long wings, short legs and very short bills. They are sometimes called goatsuckers, due to the ancient folk tale that they sucked the milk from goats (the Latin for goatsucker is Caprimulgus). Some New World species are called nighthawks, poorwills and etc.. Nightjars usually nest on the ground. The English word ‘nightjar’ originally referred to the European nightjar.
They are found around the world. They are mostly active in the late evening and early morning or at night, and feed predominantly on moths and other large flying insects.
Most have small feet, of little use for walking, and long pointed wings. Their soft plumage is cryptically coloured to resemble bark or leaves. Some species, unusual for birds, perch along a branch, rather than across it. This helps to conceal them during the day.
The Common Poorwill, Phalaenoptilus nuttallii, is unique as a bird that undergoes a form of hibernation, becoming torpid and with a much reduced body temperature for weeks or months, although other nightjars can enter a state of torpor for shorter periods.
Nightjars lay one or two patterned eggs directly onto bare ground. It has been suggested that nightjars will move their eggs and chicks from the nesting site in the event of danger by carrying them in their mouths. This suggestion has been repeated many times in ornithology books, but while this may accidentally happen, surveys of nightjar research have found very little evidence to support this idea.

Blackish Nightjar Caprimulgus nigrescens
IUCN Species Status -
Blackish Nightjar Caprimulgus nigrescens
Cornell Species AccountBlackish Nightjar is a relatively small dark nightjar, well named for its predominantly blackish plumage; this coloration provides good camouflage against this nightjar's preferred microhabitat of granite rock outcroppings in forest clearings and along trails. -

Species AccountThe blackish nightjar (Nyctipolus nigrescens) is a species of bird in the Caprimulgidae family. This relatively small dark nightjar is found in the Guianas and the Amazon. It is rare or even absent in the western part, but is among the commonest nightjars in the eastern Amazon and the Guianas. -
