General

Peregrine Falcon: Medium-sized, robust falcon with blue-gray upperparts, plain breast, and heavily barred sides, belly, and leggings. Head has a black hood and sideburns. Western race has darker underparts. Sexes are similar. Juvenile has brown upperparts and streaked underparts.

Range and Habitat

Peregrine Falcon: Breeds from Alaska and the Canadian arctic south locally through the mountainous west, and sparingly in the east. Spends winters on coasts north to British Columbia and Massachusetts. Preferred habitats include tundra, savannas, coasts, mountains, and tall buildings.

Breeding and Nesting

Peregrine Falcon: Two to six buff or white eggs, heavily marked with brown and red, are laid in a nest, often built by other species, set high on a cliff or tall building. Incubation ranges from 28 to 32 days and is carried out by the female.

Foraging and Feeding

Peregrine Falcon: Preys mostly on birds, including doves, pigeons, shorebirds, waterfowl, and passerines; also eats small reptiles and mammals. Often soars to hunt, diving to stun its prey in midair.

Vocalization

Peregrine Falcon: Call is a rasping "kack-kack-kack-kack", usually given at the nest.

Similar Species

Peregrine Falcon: Merlin is smaller, has a less-distinct moustache stripe and more strongly barred tail. Prairie Falcon has black underwing patch and lacks strong moustache stripe. Gyrfalcon is larger with broader wings and tail, and lacks the bold moustache stripe.

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.
