About Hemitriccus nidipendulus (Wied-Neuwied, 1831)
The hangnest tody-tyrant, scientific name Hemitriccus nidipendulus (Wied-Neuwied, 1831), measures 9.5 to 10 cm (3.7 to 3.9 in) long and weighs 7.2 to 8 g (0.25 to 0.28 oz). Males and females have identical plumage. Adults of the nominate subspecies have a bright olive-green crown, yellowish olive lores, and bright olive-green coloration on the rest of the face, back, and rump. Their wings are olive with yellow edges on the flight feathers and coverts, and their tail is olive. Their throat and underparts are mostly white, with faint grayish olive streaks on the breast and flanks. Subspecies H. n. paulistus has the same plumage pattern as the nominate subspecies, but it is slightly larger and has a longer tail. Both subspecies have a creamy white iris, a brown bill with a grayish pink base to the lower mandible, and light gray legs and feet. The hangnest tody-tyrant has a disjunct distribution in southeastern Brazil. The nominate subspecies occupies a small range in Sergipe and northeastern Bahia states. Subspecies H. n. paulistus has a much larger range that extends from southern Minas Gerais and Espírito Santo south to northeastern Paraná state. This species is part of the Atlantic Forest avifauna, and it inhabits humid restinga broadleaf and evergreen forests. It prefers dense woodlands, secondary forest, and thickets of the fern Pteridium aquilinum. It occurs at elevations ranging from sea level to 900 m (3,000 ft).
