Golden-cheeked Warbler (Setophaga chrysoparia)

The Golden-cheeked Warbler is related to the more widespread Black-throated Green Warbler and Townsend's Warbler, two species with relatively large ranges in eastern and western North America (respectively). However, the Golden-cheeked Warbler is unique in that it is the only species that breeds exclusively in Texas. There, they are found in the oak-juniper woodlands of Central Texas, a very small breeding range that may cover less than 350 square kilometers (IUCN 2016). They are strongly tied to the occurrence of Ashe Juniper (Juniperus ashei) due to their preference for the use of bark from that tree as a nesting material. Ashe Juniper trees must reach a certain age before the bark is suitable for use in a Golden-cheeked Warbler nest, and thus the species is dependent on suitable areas of older Ashe Juniper trees. They are considered an endangered species in the United States. Their small area of habitat in Texas has been even further reduced in recent decades due to conversion of woodlands and forests to developed and agricultural uses.

Habitat

On their breeding grounds in Texas, Golden-cheeked Warblers are primarily found in oak-juniper woodlands, particularly in areas where Ashe Juniper is present. They are found in a variety of woodland and shrubby habitats during migration, while in winter, they are restricted to mountain pine-oak forests and woodlands.

Diet

Feeds on insects and spiders.

Behavior

Forages by gleaning insects from the surface of vegetation, either while flitting or clambering through vegetation, or by making short flights. They may also capture insects in mid-air.

Nesting

The nest of a Golden-cheeked Warbler is built by the female alone, and is placed in a small tree. She uses strips of bark from the Ashe Juniper, with spider webs to as a binding material, but will also sometimes use rootlets, grasses, small bits of vegetation, or even bits of fur that it comes across. Despite the dependence upon juniper bark for nest material, the nest itself may be placed in a variety of small trees in suitable habitat. The female lays 2-5 eggs, and she alone incubates them. The eggs hatch after about 12 days, and the young fledge from the nest about 10 days later.

Song

The song of a male Golden-cheeked Warbler is a buzzy series of phrases ending on a higher note.

Migration

Golden-cheeked Warblers are only present on their Texas breeding grounds during the summer months. They migrate through Mexico to select locations in Central America for the winter. See range map below for summer and winter range extents.

Conservation Status

Populations of Golden-cheeked Warblers have been in decline in recent decades. On both their summer breeding grounds in Texas, and on their wintering grounds in Central America, habitat loss has contributed to the decline of the species. Habitat fragmentation on their breeding grounds has increased threats from Brown-headed Cowbirds , which has also had a negative impact on the species.. The IUCN currently lists the Golden-cheeked Warbler as "Endangered" .
