Whitehead's Swiftlet

Svelte with a long, pointed tail. Plain brown overall with dark spots on wing. Juvenile is covered with pale scaly pattern, but is much larger and longer-tailed than ground doves. Widespread and common throughout much of North America, from southern Canada to Panama, including the Caribbean. Found in a variety of habitats from agricultural fields to lightly wooded areas. Loves suburbs, where it often sits on telephone wires and visits bird feeders. Avoids dense forest, but found on forest edges. Usually seen in pairs or small flocks, sometimes gathering in larger numbers, especially in winter. Listen for distinctive cooing song and whistling wings as it takes off.

Extremely rare, large, elongated brown warbler with a long slender bill. Fairly similar in appearance to West Himalayan, Chinese, Baikal, and Spotted Bush Warblers, but breeding ranges do not overlap. Like other bush warblers, typically very skulking and furtive, preferring to run instead of fly when threatened. Emerges onto small bushes to sing, producing a dull clicking that would underwhelm a grasshopper. Breeds in weedy and bushy slopes in open alpine and subalpine areas; wintering habitat poorly understood but presumed to be similar habitat at lower altitudes. Very few sightings in recent years.

Large nightjar of the eastern ranges of Australia, most commonly seen in the late evening when hawking over water or over clearings in forests. Primarily dark gray, with extensive barring. All-dark tail and fairly plain wing evident in flight. Song is a unique bubbling that rises in pitch and frequency.
