Interesting Facts

The Northern Hawk Owl is also known as the Canadian Owl and Hudsonian Hawk Owl.

They have little fear of humans, and will attack if their young are approached too closely.

Their feathers are stiff, unlike those of nocturnal owl species. This means their flight is not completely silent.

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