Purple-throated Sunbird

A relatively small diving duck with a tall peaked crown. Males are handsome with glossy black head and back, clean gray sides, and a brighter white spur on the side. Females are grayish-brown, often with a paler patch at the base of the bill and a white eyering. Both sexes have a white band near the tip of gray bill. Also note gray, not white, wingstripe in flight. Usually favors small bodies of water, such as beaver ponds and cattail marshes, but also occurs on larger lakes, rivers, and bays. Can be found in mixed flocks with other diving ducks, although usually in smaller numbers than scaup. Compare with both species of scaup and Redhead (especially females).

Large trogon with a red belly and stout yellow bill. The female has a gray head and chest, while the male is emerald green with a white band separating the chest from its red belly. Note the plain dark gray undertail. Found in canopy and middle levels of lowland forest, mainly in the Amazon basin of northern South America but also in eastern Panama, northern Colombia, and western Venezuela. The similar Slaty-tailed Trogon has a red bill and males lack the white chest band seen on Black-tailed Trogons. Listen for slow series of low-pitched “coop” calls.

A large gray cuckooshrike with a strong, hooked bill. Upperparts are mostly gray with black primaries; male darker than female. Note pale patch on back and white tail tips when bird is in flight. Male is gray with a lightly barred white belly. Female has denser barring that transitions to a white lower belly and undertail. Both sexes have a dark patch from the bill to slightly behind the eye, giving a masked impression. Juvenile is brownish, heavily scaled with whitish-buff, and mottled on the underparts. Immature has broader white edges to wing feathers. Vocal. Often gives a two-noted, rather nasal “gii-yaak,” uttered in flight as well as from a perch; also gives scratchy squeal calls. Inhabits lightly wooded country, avoiding wet forests.
