Spotted Owl

Spotted Owl: Medium owl, white-spotted, brown upperparts, finely barred white underparts. Head lacks ear tufts. Eyes are brown. The wings are brown with white spots. A secretive bird, it inhabits dense old growth forests. An individual needs 3000 acres to survive due to scarcity of its food source.

● Song: "hoo-hoohoo-hoo", "hoot-hoot-hoot", "co-weeep"

● Foraging & Feeding: Spotted Owl: Feeds on flying squirrels, wood rats, gophers, small rabbits, mice, and voles. Forages from a perch, swooping down to capture prey on the ground, usually at night.

● Breeding & nesting: Spotted Owl: Lays one to four buff tinted, white eggs in stick nests of Northern Goshawks, clumps of mistletoe, large tree cavities, broken tops of large trees, large branches, or cavities in banks and rock faces. Female incubates for 28 to 32 days.

● Similar species: Spotted Owl: Barred Owl is larger and has a breast pattern of horizontal and vertical marks. Hybrid offspring show a mix of both parents’ traits.

Flight Pattern

Silent rapid wing strokes.

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.
