Interesting Facts

The Western Screech Owl was first described in 1867. Common names include Little Horned Owl, Dusk Owl, Ghost Owl, Mouse Owl, Cat Owl, Little Cat Owl, Puget Sound Screech Owl, Washington Screech Owl, and Coastal Screech Owl.

When threatened, they stretch their body and tighten their feathers in order to look like a branch stub. They become motionless if disturbed at roost, and can sometimes be caught by hand in this state.

At one time, the Western and Eastern Screech Owl were considered to be one species, but they have since been split into two separate species.

A group of owls has many collective nouns, including a "bazaar", "glaring", "parliament", "stooping", and "wisdom" of owls.

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.
