Interesting Facts

 The Whip-poor-will lays its eggs so they hatch about 10 days before a full moon. This allows the adults to forage the entire night, and so best provide the nestlings with insects.

 They fly around livestock at dusk to feed on insects swarming over the animals. It was once believed that they sucked milk from goats' udders and caused them to dry up; hence their family name, Caprimulgidae, from the Latin capri and mulgus, meaning "goat-milker."

 The record number of calls in a row by a single bird is 1,088, perhaps accounting for their species name, vociferous.

 A group of whip-poor-wills are collectively known as an "invisibility" and a "seek" of whip-poor-wills.

Tail is long and rounded with large white corner patches. Brown legs and feet. Erratic mothlike flight, flies close to the ground at night.

● Song: "WHIP-poor- WEEA”

● Foraging & Feeding: Whip-poor-will: Feeds on flying insects, usually at night, finding prey by sight and sound. Small bill opens into a huge, gaping maw when it flies after prey. Foraging results in erratic flight that includes wheeling, circling, gliding, and hovering.

● Breeding & nesting: Whip-poor-will: Two gray-and-brown scrawled, white eggs are laid in a shallow depression among dead leaves, often in younger growth near a woodland edge. Incubation ranges from 19 to 20 days and is carried out by the female.

● Similar species: Whip-poor-will: Chuck-will's-widow is larger, has more pointed wings, and is more rufous overall.

4 and 6 letter alpha codesX

The four letter common name alpha code is is derived from the first two letters of the common first name and the first two letters of common last name. The six letter species name alpha code is derived from the first three letters of the scientific name (genus) and the first three letters of the scientific name (species). See (1) below for the rules used to create the codes..

Four-letter (for English common names) and six-letter (for scientific names) species alpha codes were developed by Pyle and DeSante (2003, North American Bird-Bander 28:64-79) to reflect A.O.U. taxonomy and nomenclature (A.O.U. 1998) as modified by Supplements 42 (Auk 117:847-858, 2000) and 43 (Auk 119:897-906, 2002). The list has been updated by Pyle and DeSante to reflect changes reported by the A.O.U from 2003 through 2006.

ITIS CodesX

The Integrated Taxonomic Information System (ITIS) was established in the mid-1990�s as a cooperative project among several federal agencies to improve and expand upon taxonomic data (known as the NODC Taxonomic Code) maintained by the National Oceanographic Data Center (NODC), National Oceanic and Atmospheric Administration (NOAA).

To find the ITIS page for a bird species go to the ITIS web site advanced search and report page at http://www.itis.gov/advanced_search.html. You can enter the TSN or the common name of the bird. It will return the ITIS page for that bird. Another way to obtain the ITIS page is to use the Google search engine. Enter the string ITIS followed by the taxonomic ID, for example "ITIS 178041" will return the page for the Allen's Hummingbird.
