Halmahera Golden-Bulbul

A large, heavy-billed loon. Common and widespread in North America; somewhat less common and more local in Europe. Breeding adults have gorgeous black-and-white patterning; especially note fully black head with iridescent sheen and boldly checkered back. Nonbreeding plumage is plainer gray above and white below; note the jagged border between gray and white on the neck. Heavy bill is usually held straight (compare with Yellow-billed Loon). Breeds on lakes and ponds in the boreal forest. Listen for their haunting, yodeling vocalizations. In winter, mostly found on nearshore ocean waters and sheltered bays, singly or in loose flocks.

Odd, long-tailed, slender-billed bird. The birds in the western part of the range are brown-hooded. In the east, male birds can have a glossy green, brown, or whitish head, and females can show a brown or whitish head. Note the dark bill and legs. Found in humid forest. Usually in pairs or small groups of up to 10. There are two distinctive calls: a dry rattling given in chorus, and a mournful series of rising whistles. Similar to White-headed Woodhoopoe, but easily separated by the dark bill and legs.

Large and rather uncommon tanager found in the canopy of humid forests where it usually accompanies mixed-species flocks. Plain brown overall with a cinnamon face, wings, and tail and a dark mask running through the eyes. Its plumage mimics the Buff-fronted Foliage-gleaner, with which it is easily confused and it may even occur in the same flock, but note the tanager’s thicker bill. The thin rising song is very high-pitched.
