Family

Description

4-5" (10-13 cm). A small, bluish-backed warbler with bright yellow underparts, 2 white wing bars, and patch of olive green in middle of back. Male has orange wash on breast. Northern Parula similar, but male has orange-brown breast band.

Voice

A buzzy, ascending trill, zzzzzzzzzz-up.

Habitat

River-bottom woodlands and thickets.

Range

Breeds in Rio Grande Valley of Texas. A few winter in Texas, but most do South in Mexico. Also in tropics.

Discussion

This species has become quite scarce along the Rio Grande, the only part of the United States in which it nests, due to parasitism by cowbirds, the disappearance of Spanish moss, and the use of pesticides. During a period in the 1960s it apparently did not nest north of the U.S.-Mexico border at all, but now a few pairs breed in certain tracts of river-bottom woods.

Nesting

3 or 4 white eggs, spotted with brown, in a cup built into a mass of hanging moss, usually along a stream.
