The goatsuckers, which include common nighthawks
(Chordeiles minor), the third member of this family found in New York, belong to the Caprimulgidae family.
Estimates of relative abundance for elf owls, lesser nighthawks (Chordeiles acutipennis), and common nighthawks
(Chordeiles minor) were calculated over the 3-month sampling period of April June because these species are migratory and were present on Galvan Ranch only during that period.
The common nighthawk
as well as the whip-poor-will and chuck-will's-widow appear to be declining species, and no one knows why or to what extent.
The purpose of our study was to collect data for flight speeds of foraging common nighthawks
(Chordeiles minor) flying under natural conditions using a Doppler radar and compare them with data collected by timing flights over a known distance for the same species (Brigham and Fenton, 1991).
Sarnoff Pine Barrens Preserve in Suffolk County, which serves as a breeding area for common nighthawks
, whip-poor-wills, brown thrashers, field sparrows and other characteristic pine barrens species.
The purpose of this study was to assess the diet of common nighthawks
(Caprimulgidae: Chordeiles minor) in relation to insect abundance in the Cypress Hills, Saskatchewan.
