Endangered golden-cheeked warblers nest only in the mixed Ashe juniper and oak woodlands of Central Texas. They nest from March to July, and spend winter in Mexico and Central America. Warblers eat insects and spiders from oaks, and use long strips of cedar bark and spiderwebs to build nests, where they lay three to four eggs. Loss of nesting habitat has reduced golden cheeked warbler populations
Black-capped vireos also nest in Texas in the spring (April to July) and spend winter on the west coast of Mexico. These tiny birds nest in low-growing shrubs and return each year to the same nesting area. Males sing to attract mates and to defend two- to four-acre territories. The loss of low-growing shrub habitat (due to grazing, clearing and fire suppression) has led to this bird’s scarcity. It was removed from the endangered species list in 2018.
Field Sparrows can be found yearly in Texas. Breeding for Field Sparrows in Texas occurs from late March to late July. Their preferred habitats include areas with low perches, such as abandoned agricultural fields and pastures, fence rows, road and forest edges, as well as openings in wooded areas. Within the last few decades the population of Field Sparrows had been declining, but with the increase in forest clearing occurring in North America, the population for Field Sparrows are expected to increase.
Blue-gray Gnatcatchers arrive in Texas from February 28 to May with most being present from mid-March to mid-April. Breeding occurs from late March to late July.
Bewick’s Wren is a resident year-round in Texas where it breeds from early February to mid-August. Bewick’s Wrens breed in Texas from near sea level to 2600 m (8500 ft) in thickets and brush in semi-arid situations, often hilly.
Most Black- Chinned Hummingbirds arrive in Texas between mid-March and early May to breed from late March to mid-August. These Hummingbirds breed in Texas from 120 to 2650 m (400-8750 ft) in habitats ranging from agave-cactus desert to semi-humid juniper-live oak.
