General

Whiskered Screech-Owl: Small owl with distinct ear tufts, gray and brown mottled upperparts, and brown-streaked, white-barred underparts. Facial bristles are longer and denser than in other screech owls. Sexes are similar.

Range and Habitat

Whiskered Screech-Owl: Resident in range, in the north of its range (Arizona), there may be some down slope movements in winter. Prefers montane habitats.

Breeding and Nesting

Whiskered Screech-Owl: Two to four white eggs are laid in a natural cavity or abandoned woodpecker hole. Female incubates for 21 to 30 days.

Foraging and Feeding

Whiskered Screech-Owl: Feeds on insects, spiders, and small mammals. Hunts from a perch, flying out to catch winged prey.

Vocalization

Whiskered Screech-Owl: Main call is a long series of hoots "woot, woot, woot, woot", with emphasis on the third note and falling off towards the end. Also calls a hollow hooting, usually in duet with the slightly higher pitched female.

Similar Species

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.
