Bronze-olive Pygmy-Tyrant

Black-and-white seabird with a thick and blunt bill. Breeds in colonies on rocky islands; winters on the ocean. Black above and white below with thin white line in front of eye. In winter, white throat wraps up behind eye, but pattern is less crisp than on Common Murre. Similar to other murres but note different bill shape and longer tail that is sometimes held up. Found singly or in flocks. Sometimes seen from shore in large numbers following the passage of a winter storm. Frequently dives underwater searching for fish.

Small flycatcher found along the east slope of the Andes in western Bolivia, barely reaching over the border into southern Peru. Note the stubby bill, indistinct wingbars, and white eyebrow bordered below by a dark eye-line. Similar to Sclater’s Tyrannulet, but lacks a white throat and has less prominent wingbars. Inhabits the canopy of humid forest, and typical song is a series of three to five descending, whiny whistles. Note that some vocally distinct birds found farther north in Peru as well in western Brazil may belong to this species, but pending further research, could also be a form of Sooty-headed Tyrannulet or something completely new.

Small gray crane of open expansive habitats. Adult is an elegantly smooth shade of gray with a black neck, fiery eyes, and pure white plumes extending out from behind the eyes. Juvenile is similar but paler overall and with shorter plumes. Dark wingtips, prominent while the bird is in flight, may cause confusion with Gray Heron, but note overall shape and straight-necked flying posture (heron typically tucks neck in). Small size distinguishes this species from other cranes. Inhabits fields, deserts, steppes, and plains with water in general vicinity. May visit drier habitat in winter. Migrates in large, vocal flocks.
