Bridled Tern

Common and fairly widespread across much of North America and the Caribbean. Medium-sized songbird with a relatively long tail, small head, and short bill. Gray above and paler whitish below. Note white wingbars and large white patch at the base of the primaries. Found in a variety of open habitats with scattered bushes or trees, often close to human settlements. Well-known for its impressive mimicry; often includes a wide range of other birds, car alarms, slamming doors, and other mechanical noises in its song. Limited range overlap with Tropical Mockingbird at the Isthmus of Tehuantepec in Mexico; Northern is most easily identified by its large white wing patches.

Small bird with short, heavy bill. Green above, yellow below, with bold black-and-white head pattern. Male has black chin, female dark greenish. Found across south eastern and eastern Australia. Inhabits eucalypt woodlands and some wetter woodlands, where it tears bark noisily, looking for food. Song is loud and includes a descending three-part whistle. Also an accomplished mimic of many other species’ songs. Formerly treated as one of the geographically isolated subspecies of Crested Shrike-tit.

Uncommon flycatcher with a highly restricted range in northern Peru. It is known from white sand forest near Iquitos and from Andean foothills in the vicinity of the cities of Moyobamba and Tarapoto. Plumage is mostly yellowish-olive with a pale bill and eye and yellow fringes to the wing feathers. Very similar to Red-billed Tyrannulet, but usually shows an olive (not gray) crown; voice is a more reliable way to separate the two species. Listen for a high, piping whistle given alone or in pairs. Calls have a rasping quality in the lowland part of the range. Inhabits forest canopy.
