Hooded Yellowthroat
Geothlypis nelsoni
Rather local and endemic to highlands of Mexico. Unlike most yellowthroats, not found in marshes. Occurs in brushy scrub and chaparral thickets, where usually quite skulking, but sometimes sings from conspicuous perches. Upperparts and flanks are relatively dark greenish olive. Duskier than Common Yellowthroat, which is a common migrant throughout range of Hooded, but Common are usually near water. Male Hooded has gray border above black mask. Female has a ghosting of male pattern with some grayish on forehead, but can be difficult to distinguish from Common.

Gray's Grasshopper Warbler
Helopsaltes fasciolatus
An odd, thrush-like warbler; extremely shy and seldom seen as it lurks about in dense undergrowth. The largest grasshopper-warbler, with a distinctly robust appearance. Matte brown with pale brow, throat, and belly. Complete lack of streaking distinguishes this species from Middendorff’s and Pallas’s grasshopper-warblers; white throat and pale brow distinguish Gray’s from the much browner Pleske’s Warbler. Slightly warmer-colored Sakhalin Grasshopper-Warbler is extremely similar but has a whiter throat, a thicker brow, and more extensive brown on the underside.

Black-capped Antwren
Herpsilochmus atricapillus
Small, long-tailed antwren of the middle to upper levels of woodlands and dry forests. Males are gray with a contrasting black cap and eyebrow. The tail is black and white-tipped and the wings are black with white bars. In females note the cinnamon forehead, gray back and buff belly. The song is loud and usually given as a duet.

Thick-billed Warbler
Arundinax aedon
Bulbul-sized large warbler with a long tail, a stubby bill, and a plain face. Breeds in East Asia; winters in South and Southeast Asia. Structurally similar to Clamorous Reed Warbler but has a shorter, blunter bill, no eye-stripe or brow, different vocalizations, and no particular preference for water. Rather skulky, it keeps to dense grasses, forest edge, and shrubbery. Song is long and complex, consisting of short bursts of high piercing notes, harsh snappy chattering, and mellow warbles. Calls include a hard, fast, continuous arrhythmic “thk…thk, thk, thk” emanating but from the undergrowth.
