Yellow-bearded Greenbul
Criniger olivaceus
A fairly large and distinctive rainforest greenbul. Mostly dark olive-green, with a brown tail and some blue-gray bare skin around the eye. The bright yellow throat feathers are slightly puffy. Generally uncommon and inconspicuous in the understory and at middle levels of lowland rainforest. Similar in appearance to Western Bearded-Greenbul, but smaller, with a less puffy throat and no gray in the plumage. Similar to Red-tailed Greenbul, but has a yellow rather than pure white throat. Somewhat similar to Icterine Greenbul, but larger and much darker on the breast and belly. The song is a series of 3-4 chatty notes, sometimes ending on an upward inflection; similar to the song of Red-tailed Greenbul, but lower-pitched and less cheerful.
分类信息
Alternatively, the yellow-bearded greenbul has been classified in the genus Xenocichla (a synonym for Bleda) and has also been considered as conspecific with the white-bearded greenbul. Alternate names for the yellow-bearded greenbul include the olive bulbul, olive greenbul, olive-bearded bulbul, yellow-bearded bulbul, yellow-throated olive bulbul and yellow-throated olive greenbul. The name 'olive bulbul' should not be confused with the species of the same name, Iole virescens.

Copper Seedeater
Sporophila bouvreuil
Very small finchlike bird with a short bill. Males are unmistakable—mostly cinnamon with a black cap, wings, and tail. Females are brown above and pale below. Both sexes have a white wing spot. Females are difficult to separate from female Pearly-bellied Seedeaters, but they are less gray overall than Pearly-bellied. Found in savannas and grasslands where it is often seen in flocks with other seedeaters.
Blue-throated Bee-eater
Merops viridis
A bright green insect hunter with a long bill and triangular starling-like wings. Adult has a bright blue throat, orange-brown crown and nape, and long trailing central tail feathers. Sexes are alike. Juveniles have a paler blue throat, no orange-brown coloration, and no long tail extensions. Often hunts from exposed perches such as telephone lines or snags, on which it rubs its venomous quarry so as to disarm it. Call is a bright, inflected “chileep.”
American Golden-Plover
Pluvialis dominica
Slender, long-winged plover usually found in relatively dry habitats. Breeding plumage shows black belly and face, white neck sides, and dark back and crown spangled with gold. Note sides and undertail coverts entirely black, but beware females and molting birds can be mottled with some white. Nonbreeding plumage is much drabber; grayish overall with distinct white eyebrow and dark cap. Juveniles are crisp and neatly spangled above, washed with gold on the upperparts. At all seasons, note slender shape and narrow bill to separate from Black-bellied Plover, along with grayish underwing in flight. Extremely similar to Pacific Golden-Plover; American is slightly longer-winged, shorter-legged, and smaller-billed, but these features are difficult to judge. Juvenile American is usually duller than Pacific, especially on the face and neck. Average habitat preferences are important (Pacific Golden and Black-bellied more regular on beaches and mudflats), but much overlap. Range is also important. Breeds on Arctic tundra. Fairly common migrant through central North America, uncommon on East Coast, rare on Pacific Coast. During migration, prefers sod fields, dry mudflats, and pastures; often in small flocks, sometimes mixed with Black-bellied Plover. Winters in South America. Note voice: a plaintive “pleedoo” call.
