Yellow-crested Tanager

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.

Slim, slightly crested flycatcher with a long tail that is often fanned. The back is blue, the underparts pale gray, and the outer tail white. Found in rainforest, gallery forest, lush gardens, and thick miombo. Often joins mixed-species feeding flocks. The song is a long, complex mix of warbling and chatty notes. Similar to African Blue Flycatcher, but has virtually no overlap in range, and easily separated by its white outer tail.

A mostly rusty-colored waterfowl. Male has a gray neck and head; female similar with a whitish face. Resident and nomadic throughout its range, preferring estuaries, rivers, and impoundments within arid zones. Gives a honk call. Egyptian Goose is similar, but larger, with a brown blotch in the middle of the chest and a different head pattern that includes a tawny eye surrounded by an expanded rusty eye-ring. Egyptian Goose honk is higher and harsher than this species.
