Long-billed Thrasher
Toxostoma longirostre

At a Glance

A tropical relative of the Brown Thrasher, this species enters our area only in southern Texas. There it is a common permanent resident of native woodland and thickets, foraging on the ground under dense cover, often singing from a hidden position within the brush. When Brown Thrashers move into southern Texas in winter, the two species of thrashers maintain separate wintering territories.

Habitat

Woodland undergrowth, mesquites. In Texas, found in the brushy undergrowth of native woodlands of hackberry, acacia, ebony, and other trees, especially near water, and in dense thickets of mesquite and other thorny shrubs. In Mexico, lives in various kinds of woodland and semi-open areas.

Behavior

Eggs

3-4, sometimes 2-5. Pale blue to bluish white, finely dotted with reddish brown. Incubation is by both parents, about 13-14 days.

Young

Both parents feed the nestlings. Young leave the nest about 12-14 days after hatching. Probably 2 broods per year.

Feeding Behavior

Does much foraging on the ground, using its long bill to flip dead leaves aside as it rummages in the leaf-litter for insects; also will use its bill to dig in soil within an inch of the surface. Perches in shrubs and trees to eat berries.

Diet

Mostly insects and berries. Diet is not known in detail, but probably similar to that of Brown Thrasher. Known to eat many insects, including beetles, ants, true bugs, moths, grasshoppers, antlions, and others; also spiders and centipedes, probably small vertebrates such as frogs and lizards. Also eats many berries and wild fruits, and probably some seeds.

Nesting

Pairs may remain together at all seasons, at least in some cases. Nest: Placed in dense and often spiny plants such as shrubby mesquite, acacia, prickly-pear, or yucca, usually 4-10' above the ground. Site is usually well shaded in undergrowth of woods and in an almost impenetrable position. Nest (probably built by both sexes) is a bulky and loosely-constructed open cup of sticks, twigs, leaves, weeds, grass, and other material, lined with softer matter such as rootlets and fine grass.

Climate Vulnerability

Conservation Status

Undoubtedly declined in southern Texas with initial clearing of brushland and river woods for agriculture. Still common in remaining habitat.
