	Common Nighthawk
		Nighthawks are ground-nesters that normally breed in clearings, prairies, burned areas, cultivated fields, rocky outcrops, and other open or semi-open habitats.
		Nighthawks drink in flight, skimming the surface of a pond or stream with their lower mandible.
		Common Nighthawks migrate long distances, leaving their extensive North and Central American breeding range to winter in South America as far south as northern Argentina.

	BioKIDS - Kids' Inquiry of Diverse Species, Critter Catalog, Chordeiles minor, common nighthawk
		Common nighthawks are some of the last migratory birds to arrive at their breeding grounds in the spring, and some of the first to leave in fall.
		Common nighthawks migrate 4,000 to 11,000 km (2,500 to 6,800 miles).
		Common nighthawks that nest in cities are also in danger of predation by housecats and other species.

		It is suspected that the population of the Common Nighthawk might be in decline.
		The purpose of Project Nighthawk was to simply get some people out in the evenings and see how many nighthawks could be counted migrating in the last two hours of daylight every evening during the expected peak of nighthawk migration.

	Pennsylvania Game Commission - State Wildlife Management Agency: Common Nighthawk and Whip-Poor-Will
		The common nighthawk and the whip-poor-will belong to Family Caprimulgidae, a group of nocturnal and crepuscular birds also known as the nightjars; 80 species are found around the world.
		Common Nighthawk (Chordeiles minor) - The name "nighthawk" is a misnomer, as the bird is not related to the hawks and it flies mainly at dawn and dusk rather than at night.
		The average life span of a common nighthawk is estimated at four to five years; banded birds as old as nine years have been recovered.

	Common Nighthawk Species Account - Florida Breeding Bird Atlas
		The Common Nighthawk breeds throughout most of the state but is less common in the Lower Keys, where its range overlaps that of the Antillean Nighthawk.
		There is some indication that the Antillean Nighthawk is declining in the Upper Keys due to a southward spread of Common Nighthawks (P. Smith, in litt).
		The Common Nighthawk remains inactive during most daylight hours, therefore, it was necessary for Atlas fieldworkers to survey areas at dawn or dusk.

		The Texas nighthawk, according to Sharp (1907), is a common inhabitant of the vineyards of San Diego, Calif., where the eggs are placed on the ground under or near the vines.
		The little nighthawk struggled out of my bag and ran directly to his mother to be fed. After he was gorged with insects the female attempted to brood him, but to her apparent dismay he rushed back to the woolen bag, clearly recognizing that I could do a much better job at brooding.
		Nighthawks nesting on roofs are usually free from such molestation, but Albert F. Ganier informs me that he has known of sparrow hawks invading the cities and preying upon the nighthawks, especially the young.

		Nighthawks begin their southward migration as early as the first week of August but the bulk of the migrants are recorded after August 20.
		At present the nighthawk is restricted almost entirely to roof tops of the larger cities although in 1978 it was found nesting on the ground in Myles Standish State Forest in Plymouth, MA.

	Grand slam for the common nighthawk
		Nighthawks adapt well to cities where gravel roofs are common, as they find them pleasing roosting and nesting sites.
		Nighthawks are particularly notable for the quantities of mosquitoes they consume, good news to be sure as global warming introduces us to more tropical diseases spread by the little blood suckers, and they are elevated to full-blown terrorists.
		The nighthawk at the game may have been attracted by the vendors, as a common call of nighthawks is a nasal "beer!" or "peent." During courtship in the spring the mate impresses the female with death-defying dives, the vibrating of his primary feathers creating a loud "woof" or softer "swr, r-r-r-oonk."

	NPWRC :: Common Nighthawk
		Kantrud and Kologiski (1982) found that nesting densities of common nighthawk in the northern Great Plains were highest in areas supporting arid soils, and speculated that this apparent preference may have been caused by diminished habitat availability in more intensively farmed areas.
		Kantrud and Kologiski observed that common nighthawk habitat was characterized by high cover values for short grasses or species indicative of overgrazing.
		Effect of Habitat Alteration: The apparent preference of common nighthawk for upland native grasslands suggests that the widespread conversion of that plant community to other uses has produced a negative impact on the species.

		Another nighthawk suddenly appeared and swooped down at the perched bird, which quickly changed its position to normal, raising its head as though to counter the hostile gesture of the bird in flight.
		Its common call is a short, harsh peent, suggesting to some listeners the ground note of the woodcock.

	Northeastern Naturalist: Dynamics of territorial behavior by common nighthawks
		ABSTRACT - We describe the aggressive defense of a territory by a male Common Nighthawk against a migrating flock of conspecifics in Boston, Massachusetts.
		The Common Nighthawk (Chordeiles minor) is known to be territorial during the breeding season (Gross 1940).
		In previous studies, Armstrong (1965) and Wedgwood (1973) concluded that the primary factor in the establishment of nighthawk territories was the availability of suitable habitat with availability of food (i.e., flying insects) as the secondary factor.

		The Common Nighthawk is usually seen singly with its characteristically erratic flight, it usually flies higher and with deeper strokes than the Lesser.
		The Lesser Nighthawk is common in arid desert and valley grassland habitat, and is found lower in elevation where both occur.

		Other names sometimes applied to the nighthawk but less frequently than some of those previously mentioned are pisk, pork and beans, will-o'-wisp, burnt-land bird, and bird hawk.
		It was not a rare experience to see him crouch under his mother's breast and then by standing up quickly and rigidly topple his mother so that she was forced to extend her wings to keep from falling over.
		Enemies.--The greatest enemy of the nighthawk has been man. In the past great numbers of the birds were killed for food and often for mere sport or for satisfying a lust for killing.

		The common nighthawk, like the whip-poor-will, is most active at twilight, using the approaching day or night to catch insects on the wing.
		Historically, the common nighthawk sought out open, bare ground and grasslands for laying eggs, but during the last 100 years, these birds have shifted to utilizing more urban sites, using flat gravel roofs to raise their semiprecocial chicks.
