The nighthawk is a nocturnal bird of the subfamily Chordeilinae, within the nightjar family, Caprimulgidae, native to the western hemisphere. The term "nighthawk", first recorded in the King James Version of 1611, was originally a local name in England for the European nightjar. Its use in the Americas refers to members of the genus Chordeiles and related genera was first recorded in 1778.[1]

Nighthawks are medium-sized birds with long wings, short legs, and very short bills. They usually nest on the ground. They feed on flying insects. The least nighthawk, at 16 centimetres (6.3 in) and 23 grams (0.81 oz), is the smallest of all Caprimulgiformes. Nightjars are sometimes referred to as goatsuckers from the mistaken belief that they suck milk from goats (the Latin for goatsucker is Caprimulgus).

In October 2018, the University of Alberta published research on the common nighthawk revealing that it travels 20,000 kilometres every year during migration between the rainforests and savannas of Brazil and its breeding grounds in northern Alberta. [2]

Nighthawks 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 perch facing along a branch, rather than across it as birds usually do. This helps to conceal them during the day. The female lays two patterned eggs directly onto bare ground.

They are mostly active in the late evening and early morning or at night and feed on moths and other large flying insects. The bill opens very wide and has a slightly hooked upper tip.

Nighthawks are similar in most respects to the nightjars, but have shorter bills and plumage that is less soft. Nighthawks are less strictly nocturnal than many nightjars and may be seen hunting when there is still light in the sky.

gollark: Put it in *all the hatcheries*.

gollark: Wait, which egg is this?

gollark: Put it in hatcheries maybe.

gollark: I'm personally quite excited for the APocalypse of random dragons.

gollark: ```Coffeehorse Dragons received their name due to their horse-like physique and endearing behavior. They are capable of surviving out of coffee, and when on land their skin secretes a gelatinous goo to retain caffeine. However, their large paddle feet are better suited for swimming, and coffeehorse dragons tend to move very awkwardly when on land. Coffeehorses are very friendly dragons and enjoy playing with humans.```
