Olivaceous piculet Olivaceous piculet The olivaceous piculet ("Picumnus olivaceus") is a species of bird in the family Picidae. Etymologically, piculet is as a double diminutive of the Latin "picus", "woodpecker", see also Picus. In Greek, δρύοψ is woodpecker, which shares its roots with δρῦς, 'tree'; 'oak' and Druids. Found in Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Nicaragua, Panama, Peru, and Venezuela, its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and heavily degraded former forest. Upper parts plain olive-brown, crown and nape spotted white on blackish, tail short, not sharp-tipped, black with a prominent yellow center
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.
