Yellow-bellied Tanager
Ixothraupis xanthogastra
A small, colorful bird of forest canopy. Mostly bright green spotted heavily with black; the wings are bluish and the belly clear yellow. Occurs in humid lowland and Andean foothill forests in central and western Amazonia; in eastern part of range it is mainly found in tepui foothills but is perhaps overlooked in lowlands. Usually observed in mixed-species flocks, especially with other tanagers, moving quickly through canopy feeding on insects and fruit. Makes a variety of high-pitched calls, especially in flight, similar to other small tanagers and not particularly helpful in identification. Told from Speckled and Spotted tanagers by bright yellow (not white) belly, and from Dotted Tanager by yellow belly and extensive black spotting on head and breast.

Silvered Antbird
Sclateria naevia
Unique-looking antbird with a strong affinity for water. Medium-sized and chunky with a rather long bill. Male is medium-gray with a white throat and white spotting on the wings. Note the messy scaly appearance on the breast. Female is similar in pattern but is brownish overall, not gray. Note pale pink legs on both sexes. Widespread and reasonably common throughout much of lowland northern South America, east of the Andes. Almost always found in pairs near the edge of rivers or lakes in lowland forest.
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.
Black-fronted Tyrannulet
Phylloscartes nigrifrons
Small flycatcher of humid tepui forests. Best field marks are grizzled black-and-white face, dark lores, and gray crown. Also note clean grayish-white underparts. Found in forests at middle and higher elevations (above 800 m) on tepui slopes, where it typically occurs in pairs and forages actively for insects, often joining mixed-species flocks. Generally gives only indistinct chip notes while foraging, but may also give an arresting, staccato rattle very unlike other birds in range. Most likely to be confused with the more common Chapman’s Bristle-Tyrant but has conspicuously dark lores and a gray crown and lacks yellow tones on breast and belly.
