Nava's Wren

Relatively colorful, mid-sized, long-tailed cisticola of wetlands. Note the heavily streaked back and rump, and rufous in the cap, wing, and tail. Found in and adjacent to dense wetland habitats. Distinctive song is an introductory “chip” note or two followed by a quick, warbled jumble. Similar to Winding Cisticola, but Levaillant’s has a rufous tail and a streaked rump. Relatively bold colors separate the two from other cisticolas.

Small, plump, and short-tailed. Unmistakable male is glossy black with clean white cap. Female is dull olive-green and similar to other manakins; look for contrasting grayish head and brownish-red eye. Found in the lower or middle levels of forest, often at a male display site or a fruiting tree. Widespread from Costa Rica through much of northern South America.

Dark-bodied tern of tropical offshore waters, rarely seen from mainland. Breeds in colonies on rocky and sandy offshore islets. Sometimes found with offshore feeding flocks of boobies and other terns. Feeds by picking from the surface, not plunge-diving like most terns. Adult solidly dark brown with white cap. White limited to the forehead on immature.
