Thick-billed Parrot © Christopher Wood, from the surfbirds galleries.American Bird Conservancy’s Mexican partner Pronatura Noreste is reporting another successful year for the Thick-billed Parrot nest box program.
The endangered Thick-billed Parrot breeds primarily at three sites in Mexico’s western Chihuahua state. Due to harvesting of timber and fires, the large trees that provide nest cavities for the birds have almost disappeared. Many of the remaining tree cavities are damaged with cracks and openings, and others have built up large numbers of parasites from repeated use year after year. Weather conditions and nestling parasitism have seriously reduced fledging success from these remaining natural cavities.
