Yap White-eye

Breeding male is distinctive with black body, white rump, and creamy nape. Females and nonbreeders are drastically different, yellow-brown with fine streaking on breast sides, and stripes on head. Smaller than Red-winged Blackbird with shorter bill. Spiky tail feathers. In the blackbird family, although often mistaken as a sparrow. Breeds in open fields. Listen for male's bubbly song. Often in flocks during fall migration; departs early for wintering grounds in South America.

Distinctive large shorebird with a long, thin, upturned bill. Look for bold black-and-white wings and long blue-gray legs. Breeding adults have buffy-orange wash on head and neck; grayish in winter. Females have more sharply upturned bills than males. Widespread and fairly common in North America, although rare or absent from much of the eastern U.S. Usually seen in flocks, sometimes numbering into the hundreds, foraging in shallow wetlands or estuaries. Feeds by swinging its head back-and-forth through the water to catch small invertebrates.

Medium-sized inconspicuous antbird of lowland rainforest. Note gray (male) and brown (female) plumage, large bill, and lack of strong pattern on wing coverts. Found inside forest, often in pairs; may follow mixed-species flocks but often encountered alone, foraging deliberately in the mid-story or lower. Heard far more often than seen; song is a distinctive, short series of complaining notes with a characteristic doubled note at the end. The song is slower and more inflected than the song of Plain-winged Antshrike.
