Abstract

I reviewed all published reports of the Ivory-billed Woodpecker (Campephilus principalis), including specimen and sight records from Texas. A total of 25 published records and two U. S. Biological Survey unpublished reports revealed three specimen records and 44 sight records. Also, a sound voucher of the "double-knock" of a presumed Ivory-bill in Texas appears on an album of bird songs. This compilation reveals additional reports not published in Oberholser (1974), which is considered to be the main source of historical data for Texas. The intent of this paper, many decades later, is not to determine the validity of each sight record, but problems discriminating Ivory-bills from similar Pileated Woodpeckers (Dryocopus pileatus) was prevalent in the past thus warranting additional documentation of purported Ivorybilled records.
