White-naped Swift

Streptoprocne semicollaris

Very large, spectacular swift of highlands in west Mexico, also descending locally to foothills and lowlands. Often in flocks, at times of hundreds, especially around waterfalls and other roosting sites. Flight fast and strong, often soaring in kettles with wings spread in paddlelike bulges. Note the very large size, thick white nape band (often visible in a side view), and slightly notched tail (tip squared when ​tail is spread). Varied screaming and chattering calls can suggest parakeets.

Caatinga Cacholote

Caatinga Cacholote

Pseudoseisura cristata

Unmistakable. Large ovenbird with uniform cinnamon plumage, bushy crest, and yellow eyes. Occurs in dry forests (caatinga) and scrub, often near human habitations. Mostly forages on the ground. Builds a large thorny stick nest. Sings in a duet: the male emits an accelerating series which finishes in a rattle, and the female gives continuous buzzy “zjeep” notes.

Puerto Rican Tody

Puerto Rican Tody

Todus mexicanus

A tiny, brilliant-green resident of wooded habitats. There are no similar species within its range. Typically perches at low to middle levels in the forest and sallies forth to snag insects from the undersides of leaves. When not actively pursuing a meal, sits rather motionless. Most active, and thus most easily seen, when the sun comes out following rain. Most often first detected by its voice: a loud buzzy “zhip, zhip.”

Crimson Seedcracker

Crimson Seedcracker

Pyrenestes sanguineus

A chunky-billed brown finch with an electric-red rump, red tail, and red hood that extends from the throat to the nape; the hood of the male is larger than the female’s and extends down the flanks. Juvenile is duller than the adult. A secretive and uncommon resident restricted to Upper Guinea, found in pairs in swamp forest, scrub near creeks, and thickets near water in primary and secondary forest; also sometimes in cultivation. Song is a variable series of buzzes and whistles, and call is a strident “tsut…tsut.” Male Black-bellied Seedcracker differs from Crimson by having a black (not brown) back and belly; females and juveniles are almost identical but only overlap in eastern Ivory Coast.
