Overview

Ivory-billed Woodpecker: Largest and rarest North American woodpecker, jet-black with white wing patches, large red crest, black chin, throat. Thick white stripes extend from bill to rear of wings. In flight, wings appear white with black tips and thick, black center stripe. Pale, large bill.

Range and Habitat

Ivory-billed Woodpecker: Historically ranged in southeastern U.S., from Ohio River Valley to east Texas, the Gulf coast, and Florida; thought to be extinct for more than 60 years, but possibly rediscovered in the "Big Woods" region of eastern Arkansas. Preferred habitats include old growth, bottomland forests. Even healthy populations of Ivory-billed Woodpeckers were sparse, needing about 16 square kilometers to support one pair.

Interesting Facts

Considered extinct for many years, there has been recent evidence that the Ivory-billed Woodpecker may still live. In 2004, there was a reported sighting in the Cache River National Wildlife Refuge of Arkansas. Scientists believe the evidence of the continued existence of these birds is credible. Since 2004 there have been reports of sightings in Florida as well. However, these are not as well substantiated.

It was given the species name principalis because it was believed to be the largest woodpecker. In fact there are at least two larger, one from Mexico and one from Southeast Asia.

This species also experienced dire persecution. For example, in Cuba, it was hung outside homes to prevent witchcraft.

A group of woodpeckers has many collective nouns, including a "descent", "drumming", and "gatling" of woodpeckers.

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.
