Ivory-billed woodpecker  (Campephilus principalis)

The ivory-billed woodpecker is the fourth or fifth largest woodpecker in the world (4). It was previously considered to be extinct but recent evidence provides some hope that the species may still cling on in remote areas of Cuba and Arkansas in the U.S. (2) (4). The bill is, as the name suggests, ivory-white in colour whilst the feet and legs are grey (3). These birds are predominantly black with striking white stripes on the side of the neck and large white wing patches (2). Males are distinguished by their prominent red crown (4). The most commonly recorded call was an alarmed ‘kent' or ‘hant', which has been described as sounding like a toy trumpet or clarinet. Nestlings produce weak ‘buzzing' vocalizations (3).
