Ochraceous Piculet

The ochraceous piculet (Picumnus limae) is a species of bird in subfamily Picumninae of the woodpecker family Picidae. It is endemic to north-eastern Brazil. == Taxonomy and systematics == The ochraceous piculet is monotypic according to the South American Classification Committee of the American Ornithological Society, the International Ornithological Committee, and the Clements taxonomy. However, BirdLife International's Handbook of the Birds of the World (HBW) treats the darker, southern, population as a separate species, the tawny piculet (P. fulvescens). The other three taxonomic systems had earlier separated them but have concluded that the color differences used for the differentiation are along a cline and that any division is arbitrary. The distribution along the color cline generally follows Gloger's rule. This article follows the single-species model. == Description == The ochraceous piculet is about 10 cm (3.9 in) long and weighs 8 to 12 g (0.28 to 0.42 oz). Adult males have a black cap with red tips on the forehead feathers and small white spots on the rest of the cap. Adult females are identical but for no red on the forehead. The species' upperparts vary from grayish to brownish with a whitish nape. Their underparts vary from whitish yellow…
