Range and Habitat

Northern Pygmy-Owl: Resident on the Pacific coast from southern Alaska to Central America; also found in the Rocky Mountains. Preferred habitats include open coniferous and mixed forests, open fields, wetlands, and logged areas.

Breeding and Nesting

Northern Pygmy-Owl: Two to seven white eggs are laid in a nest built in an old woodpecker hole, usually in a conifer. Eggs are incubated for 29 days by the female; male brings her food while on the nest.

Foraging and Feeding

Northern Pygmy-Owl: Prey consists of birds, such as swallows, jays, and chickadees, and mammals, such as shrews, moles, and chipmunks; a predominantly sit-and-wait predator that hunts by day.

Vocalization

Northern Pygmy-Owl: Primary call of the male is a series of repetitive, whistled hoots "too-too-too-too-too-too-too", given at intervals of one to two seconds; also makes a high whinny when bringing food to his mate. Female has a cackling call. Other calls include an ascending staccato series of whistles; when excited, may emit a high-pitched trill.

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.
