Introduction

The Golden-cheeked Warbler is a migratory songbird that breeds only in Ashe juniper woodlands. Between 1960 and 1980, the area of this habitat was reduced by development pressures in central Texas by about a quarter. In addition, anticipation that the warbler would be federally listed as an endangered species prompted landowners to deliberately destroy more habitat in 1990. Breeding habitat is now fragmented and limited to the Edwards Plateau in central Texas, and it remains under severe pressure from human activity.


Threats

Habitat loss and fragmentation represent the clearest threats to the Golden-cheeked Warbler. Suburban sprawl remains the primary danger, but grazing, logging of the Ashe juniper, and mineral extraction activities are also encroaching on habitat. Nearby agriculture has also brought the Brownheaded Cowbird, which lay eggs in warbler nests that reduce the survival rates of warbler chicks.

Population and Trends

Based on a 1990 survey cited in a 1999 Birds of North America account by Clifton Ladd and Leila Gass, BirdLife International estimates the 2005 population of the Golden-cheeked Warbler to be as few as 9,600 individuals or a many as 32,000. This bird’s population is declining rapidly due to habitat loss.

Conservation

The U.S. Fish and Wildlife Service lists the Golden-cheeked Warbler as endangered. Preserving the little remaining habitat of this bird is essential. Funding for suitable habitat research on its wintering range is needed. More cowbird control projects could also help increase Golden-cheeked Warbler reproduction.
