Yellow-tailed Oriole
Icterus mesomelas
Flashy black-and-yellow oriole of humid tropical lowlands. Favors tangles and thickets along rivers and near water, also overgrown fields. Usually in pairs, often rather skulking. Both sexes have black back and wings with a big yellow shoulder bar, black tail with yellow sides that flash in flight. Immature has same pattern but duller, with a greenish back. Rich whistled song has a rollicking, rhythmic cadence.

Slaty-capped Flycatcher
Leptopogon superciliaris
Small flycatcher with gray cap, black ear patch, and buffy wingbars. Head pattern looks messy. Olive back and pale yellow belly. Most similar to Sepia-capped Flycatcher, but that species has a brown cap (not gray). Also very similar to bristle-tyrants of South America but note buffy wingbars and voice—a commonly heard, explosive “pseek!” sometimes with a sputtering trill at the end. Look for singles or pairs in forests and edges, usually not too high in the trees. Often follows mixed-species flocks.
Plain-breasted Piculet
Picumnus castelnau
Relatively plain piculet found in dense riverine and secondary vegetation along the Amazon and its tributaries in Peru, barely making it into southernmost Colombia and westernmost Brazil. Plumage generally pale below with a brownish back. Note the dark spots in the ear coverts; the short, sharp bill; and the glossy red feathers in the male’s crown. Song is a very high-pitched series of thin whistles, dropping at the end.
Mute Swan
Cygnus olor
Huge white bird with long neck, reddish-orange bill, and black face. Adults have a black knob on top of the bill. Immatures are dusky brown with a gray bill. Native to northern Europe and Asia, but introduced in many regions, where it is now common on ponds, lakes, and calm coastal waters. Very aggressive toward native waterfowl. Often seen in pairs or small family groups.
