Interesting Facts

The Yellow-crowned Night Heron is listed as threatened in the state of New Jersey and endangered in Wisconsin and Pennsylvania.

Occasionally it will prey on small turtles; its stomach secretes an acid capable of dissolving the shells.

Unlike other night herons, it is active during the day as well as at night.

A group of herons has many collective nouns, including "a battery of herons", "a hedge of herons", "a pose of herons", "a rookery of herons", and a "scattering of herons."

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.
