Varzea piculet "endangered". Varzea piculet The varzea piculet ("Picumnus varzeae") is a species of bird in the family Picidae, the woodpeckers, piculets, and wrynecks. It is endemic to Brazil's Amazon basin where it occurs in seasonally flooded Várzea forests, which gives the bird its common name. Its natural habitat is tropical moist lowland forest, and as the trees are progressively being cleared in the Amazon basin, the population of the bird is declining, and as a consequence, the International Union for Conservation of Nature has rated it as an "endangered species". This species was first described in 1912 by the German-Brazilian ornithologist
Black-dotted piculet Sucre, a few have finely barred chests. Rare individuals with scaly throats and pale buffy (rather than yellow) underparts resemble the scaled piculet, which can be distinguished by its scaly lower underparts. The crown is black with narrow scarlet streaks on the forepart and conspicuous white dots on the rear part, or throughout in some females. The upperparts are light olive-brown, slightly yellowish, with dusky spots on the shoulders and back. The song is "2 to several extremely high, thin notes, each slightly lower than the preceding, "tseeet, tseeet, tsee," etc." Possibly it is also used as a contact call.
