Interesting Facts

The Clark’s Nutcracker has a special pouch under its tongue in which it carries pine seeds long distances to cache them. Depending upon the species of pine seed, this pouch will hold from 28 and 90 seeds.

Unusual among members of the crow family, males of this species help the females incubate the eggs. In fact the males have brood pouches just like the females. Nestlings are fed pine seeds from the parents’ caches. This allows the adults to breed as early as January or February despite the harsh winter weather in their range.

This bird was first observed in 1805 by William Clark (Lewis and Clark expedition) and bears his name.

A group of nutcrackers has many collective nouns, including a "ballet", "booby", "jar", and "suite" of nutcrackers.

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.
