Spot-backed Puffbird

A small seedeater with a sharp bill and a forked tail. The upperparts are olive-green and the underparts yellow. Males have a black face and plain yellow underparts. Females have a plain face, but are heavily streaked below. Found at middle and high elevations in a variety of habitats including forest edge, gardens, cultivation, moist scrub, and woodland. Usually in small flocks. Similar to Southern Citril, but there is virtually no overlap in range, and the male is easily separated by its black face. The song is a fast jumble of high-pitched twitters and whistles. 

Fairly common endemic woodpecker in desert interior habitats of southwest Mexico, especially in areas with tall columnar cacti, including towns and villages. Often in pairs or small groups. Rather drab and grayish overall with a whitish forehead patch and a densely barred black-and-white back. Male has red crown patch and female has plain gray head. No similar species in its limited range.

Mouse-brown above and white below. Head brown with a white throat above a variable black band. White stripe extends behind eye. Long tail is often fanned. Prefers forest habitats, especially along waterways. Song is a mix of whistles, harsh chipping, and scolding chatter.
