Interesting Facts

The Peregrine Falcon is the fastest bird on record when in diving posture, called a stoop, at 175 mph or more.

These falcons were given Endangered Species status after decimation of the population from exposure to DDT in insecticides. A successful recovery effort resulted in removal from the U.S. list in 1999.

The Latin name “peregrinus” means “coming from foreign parts” which is fitting because they have one of the longest migrations of any North American bird.

A group of falcons has many collective nouns, including a "bazaar", "eyrie", "ringing", "stooping up", and a "tower" of falcons.

● Breeding & 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.

● 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 codes

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.
