Pale-chinned Flycatcher

Tiny waterbird, the size of an elongated grapefruit. In nonbreeding plumage, they are black above and white below with a black stripe on the side of the neck and a white comma behind eye. Short, stout bill. Horizontal posture like a football floating on the water. Dives frequently when feeding. In winter, only likely to be seen from land following the passage of a storm, otherwise stays well offshore. Found singly or in flocks. Much smaller than guillemots or puffins, with fast wingbeats and low, twisting flight that recalls a flock of sandpipers. Breeds in large numbers in Greenland and Europe; rare at alcid breeding colonies in Alaska. Birds in breeding plumage have an all-black head and chest.

Small, very plain brown swallow with a white belly. Found in a variety of open habitats, including marshes, rice paddies, other agricultural fields, secondary forest, and montane heathland. Found at middle and high elevations, and absent from the lowlands. Most often seen on the wing, sometimes in flocks, which can also contain other species of swallow or swift. Weak, fluttering flight. The common vocalization, usually given in flight, is a short, slightly descending rattling trill. Somewhat similar to Mascarene Martin, but much smaller and plainer, lacking streaking on the underparts.

Small plover with streaked upperparts, strong white eyebrow, and a heavy black line through the eye. Note red eyering. Adult has distinctive black V on chest. Very common around freshwater wetlands.
