About Picumnus temminckii Lafresnaye, 1845
The ochre-collared piculet (Picumnus temminckii Lafresnaye, 1845) measures 9 to 10 cm (3.5 to 3.9 in) in length and weighs 10 to 12.5 g (0.35 to 0.44 oz). Adult males have a black cap: the forehead feathers have red tips, and the rest of the cap has small white spots. Their face is mostly rich buff-brown, with a white stripe behind the eye. Their hindneck has a cinnamon-buff collar, which gives the species its English common name. Their upperparts are brown, sometimes marked with very faint paler bars. Their flight feathers are dark brown, with narrow buff edges. Their tail is blackish; the innermost pair of tail feathers have mostly white inner webs, and the outer two pairs have a white patch near the tip. Their chin and throat feathers are pale buffish white, with narrow blackish edges. Their underparts are mostly whitish, with buff coloration on the flanks and lower belly. Their iris is brown, the orbital ring is grayish, the bill is black with a grayish base, and the legs are grayish. Adult females are identical to males, except they do not have red on the forehead. Juveniles are duller and darker than adults, with heavier but more diffuse barring on the underparts. The ochre-collared piculet is distributed from São Paulo state in southeastern Brazil south through eastern Paraguay into Misiones Province in northeastern Argentina. It primarily inhabits lowland rainforest containing bamboos, vines, and tangled growth, but it can also be found in secondary growth, thickets, tall scrub, and parks and gardens. It occurs at elevations ranging from sea level to 800 m (2,600 ft).
