Sierra Madre Sparrow
Xenospiza baileyi
Very local and endangered small sparrow of highlands in central Mexico; endemic. Occurs in bunchgrass within areas of open pine woods; often rather elusive. Feeds on the ground in grassy areas and adjacent plowed fields, but sings from prominent grass stalks. Plumage looks much like Song Sparrow, with gray face, black-streaked breast and flanks, and rusty wings. Song Sparrow is larger and bulkier, with less extensive rusty in wings, and almost always lives in wetter habitats.

其他鸟类
Small-headed Elaenia
Elaenia sordida
Medium-sized flycatcher with a small head and long tail. Found in forests and second growth. Largely olive-brown above with a light gray throat and flanks, and a yellow center to the belly. Note two pale wingbars. Song a harsh and squeaky “weehr-drrrr-whee."
Yellow-bellied Dacnis
Dacnis flaviventer
Small, sharp-billed tanager of tropical lowlands. Males have a black back, bright yellow underparts, and a black mask. Females are brown above and dull yellow below. Both sexes have bright red eyes. Females similar to other female dacnis, but note red eyes and higher contrast between brown upperparts and lighter tan underparts. Found in young rainforest, forest edges, and similar open forested habitats, where it forages in the canopy singly or in pairs, often joining mixed-species flocks.
Desert Cisticola
Cisticola aridulus
Small, pale brown, heavily-streaked cisticola. Plumage is darker in breeding plumage, washed-out in non-breeding plumage. Found in dry, open grasslands, including open stretches within savanna. Song is a mix of high-pitched peeps, scratchy lower notes, and “tic” notes. Extremely similar to Zitting Cisticola. Best distinguished by song, though subtle plumage differences include Desert’s more uniformly blackish tail and slightly streaked rufous rump.
