Greenish Warbler

Shockingly bright warbler of swamps and wet forest. Adult males have gorgeous yellow head and body with greenish back and blue-gray wings. Females and immature are slightly duller but still distinctive. Breeds in wet deciduous forests, primarily in the southeastern U.S. Winters to northern South America, where still has an affinity for wet forests, including mangroves. Typically stays in the understory, but males can perch up high when singing. Listen for loud, piercing series of 6-10 “tsweet” notes. One of only two warblers that nests in cavities.

Handsome, mostly silvery gray bird of tropical lowland forest and adjacent semi-open areas with taller trees. Usually found at mid-upper levels of fruiting trees, sometimes in small groups that mix readily with the commoner Masked Tityra. Black-crowned is told from slightly larger Masked by its solidly black bill. Male is more silvery overall, with a black cap; female had brown face and smaller black cap. Tityras nest in tree cavities, that they sometimes steal from woodpeckers.

A large, dark grayish brown kiwi with reddish brown streaking. The only kiwi found in the wild on the mainland of New Zealand’s North Island. Found in both native and exotic forest, scrub, and neighboring farmland. More often heard than seen. Male call is a series of clear rising whistles. Female call is a harsh throaty wail. Both sexes repeat their call many times. Often heard at night foraging as it sniffs loudly, tapping the ground for invertebrates. Could be confused with Weka by voice and shape; look for the kiwi’s much longer bill and lack of tail, and listen for its multisyllabic call.
