Pearly-vented Tody-Tyrant
Hemitriccus margaritaceiventer
A very small flycatcher with a long bill for its size and a yellow eye. It is olive-brown above with whitish wingbars and indistinct streaking on white underparts. Considerable variation exists among subspecies in the color of the belly (gray or yellow) and the color of the back (dark gray or brown). Occurs in woodlands, shrubby habitats, and pastures with shrubs where it can be found foraging in the lower and middle levels; mostly in pairs. The song is sharp and descending series of trills “tick-tick-tr’r’r’r’r’r’r’r.”

Muscovy Duck
Cairina moschata
Large, hefty duck that has wild and domestic types. Wild birds are dark blackish overall with iridescent green and bronze, especially on the wings. Look for bold white wing patches in flight and red warts on the face (more extensive on males). Tends to be shy and most often seen in flight over extensive wetlands or along large rivers. Occurs extensively throughout Middle and South America, but typically scarce. Very restricted range in the U.S., only known from the Rio Grande Valley in Texas. Domestic birds, on the other hand, are regularly found walking around in parks and farms, looking for scraps of food and chasing native waterfowl. Plumage varies from all white to all black, typically with more extensive red warts on the face than wild birds. There is a well-established feral population in Florida, with smaller domestic populations spread across the globe.
Crested Goshawk
Lophospiza trivirgata
Powerfully built hawk of forests, especially hilly woods. Namesake crest is usually held low and not very visible. Adult has a gray head, brown wings, whitish underparts with thick orange-brown stripes in belly and streaks in breast, and white throat with black borders. Juvenile similar but with brown head, sparingly marked underparts, and very short crest. Appears stockier and relatively shorter-tailed in flight than other accipiters. Flying adults may also show a fluffy white clump of feathers on both sides of the tail.
Jerdon's Nightjar
Caprimulgus atripennis
Large-headed nightjar with a bright white throat. Male shows bright white patches near the wingtips and on the edges of the tail that are buffy-brown in females. Large-tailed Nightjar is very similar; in Jerdon’s, look for less-streaked crown and smaller wing patches. Indian Nightjar is smaller and much more intricately patterned, lacking the white throat. Song is a strange bubbling “bwr-wr-wr,” usually heard at dusk or dawn in wooded areas.
