Capuchinbird
Perissocephalus tricolor
Large, bizarre bird of tall rainforest. Unmistakable even when seen briefly, as they often are, flying quickly across roads or rivers. Appears broad-winged and mostly burnt orange with a disproportionately small head. Feeds on fruit in the forest canopy. Far-carrying display call of lekking males is one of the strangest avian sounds, similar to a distant chain saw or cow; males on leks can seem almost oblivious to human observers.
识别特征
The capuchinbird is a large thick-set suboscine passerine with a relatively heavy bill. Adults weigh between 340 and 420 grams (12 and 15 oz) and are typically around 40 centimetres (16 in) long, making it the largest suboscine passerine, apart from the Amazonian and long-wattled umbrellabirds – indeed, females average larger than any female umbrellabird. Its plumage is overall rich brown, approaching orange on the belly and undertail coverts, and the remiges and short tail are black. The most distinctive feature is its bare, almost vulture-like head covered in dull blue skin. Juveniles resemble adults, with the exception of some downy feathers on the head.

行为
They gather in leks where they "sing". The "song" is very odd and difficult to describe accurately, although some have compared it to the distant sound of a chainsaw or (as indicated by its alternative name "calfbird") a young cow mooing. The nest is small and rather scanty and is normally found in close proximity to the lek. Capuchinbirds eat mainly fruits and insects.

Northern White-fringed Antwren
Formicivora intermedia
An attractive, fairly long-tailed antwren of Colombia and western Venezuela. Males are grayish-brown above and black below with a thick white eyebrow that connects with the white sides. Also note bold white spots on wings and tail. Females are whitish below, often with bits of dark streaking on the breast sides. Also look for white eyebrow and wing spots. Look for pairs foraging in the lower levels of dense shrubby woodland, often remaining fairly hidden and difficult to see clearly. Typically occurs in the lowlands up to around 1,000 m. Listen for a series of rather musical clucking notes.

Lesser Crested Tern
Thalasseus bengalensis
Elegant medium-sized tern with a slender yellow-orange bill and black crown. Can be confused with Great Crested Tern; note proportionally longer, more orangey bill on Lesser Crested. Also note gray upperwing, which separates it from Sandwich Tern. Gray rump and tail are diagnostic if seen well. On juveniles, note dull legs, secondaries with dark centers, and a weakly patterned upperwing. Strictly coastal, usually found on beaches and estuaries. Call a noisy “kerrrick.”

Swamp Greenbul
Thescelocichla leucopleura
A loud, boisterous greenbul that is dark gray-green above and pale below. The back, head, and cheeks are all brownish, but feathers on the head have white centers that give them a distinctly grizzled appearance. The underparts grow plainer and whiter toward the tail, which is long and brown with bright white outer feather tips. Most often found near wet, swampy forest, particularly in areas with Raphia palms. Swamp Greenbul flocks are often located by their cacophonous calls, which consist of a series of notes and cackles that are reminiscent of a recorded human conversation being played too quickly.
