Interesting Facts

Boat-tailed Grackles from different regions (East Coast, Florida, west of Florida to Louisiana and west of Louisiana) have different eye colors. The reason is unknown.

They have an unusual mating system. Females locate their nests in a cluster or colony. Males compete for the right to defend and mate with all the females. This is known as harem defense polygyny.

Fledglings that fall into the water can swim well for short distances, using their wings as paddles.

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.
