Interesting Facts

The Whiskered Screech Owl is also called the Arizona Whiskered Owl, Spotted Screech-Owl and Whiskered Owl.

They are the smallest of the three Screech-Owls that occur in North America. All three Screech-Owls are very similar in appearance and can only positively be distinguished in the field by their call.

Their call is a series of soft hoots, long and short notes interspersed, which has been likened to Morse code.

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.
