Hudson's Black-Tyrant
Knipolegus hudsoni
Highly migratory flycatcher that breeds in central Argentina from around September through March, then disperses north to Bolivia and Paraguay, and occasionally wanders even farther. Male is glossy black with a silvery, black-tipped bill. He has a white on the underside of the wing that is usually hidden while perched. Female is brown and buff with white wingbars, cinnamon rump and tail base, and faint mottling on the breast. Very similar to White-winged Black-Tyrant; female is paler on the breast and belly, but males are virtually indistinguishable in the field. Inhabits stunted forest, scrub, and overgrown clearings.

Black-faced Spoonbill
Platalea minor
Large white waterbird with a long spatula-shaped bill. Breeding adults have long plumes on the head and a smudging of yellow on the chest. The extensive black facial skin distinguishes this species from the Eurasian Spoonbill, the only other spoonbill in range. Often gathers in large flocks, occasionally mixing with Eurasians. Forages in mudflats, estuaries, lakes, and large marshes, sieving out aquatic invertebrates from the water, often in a side-to-side motion.
Black Eagle
Ictinaetus malaiensis
Large and distinctive dark eagle of forested mountains and hills. Adults appear all dark from a distance, but closer inspection reveals pale barring on the primaries, secondaries, and undertail, as well as a bright yellow bill and feet. Readily separated from other large birds of prey in range by structure as well as coloration; Black Eagles have broad wings with distinct “fingers”(emarginated primaries) in the tip, as well as a long tail that is fan-shaped when open and slightly wedge-shaped when closed.
Snowcap
Microchera albocoronata
Tiny hummingbird; male is unique and beautiful: his body is the color of red wine, and he has a bright white cap. Unmistakable in limited range. Female is less striking, but note small size, snowy white underparts, and short straight bill. Most often seen feeding at small purple flowers in gardens and forest edges
