- P. o. olivaceus Lafresnaye, 1845

The olivaceous piculet and the
Description
The olivaceous piculet is 8.5 to 10 cm (3.3 to 3.9 in) long and weighs 10 to 15 g (0.35 to 0.53 oz). Adult males of the
The other subspecies have some differences from the nominate. P. o. dimotus has more of a greenish tinge to the upperparts, is paler and more olive below, and has yellow-orange tips on the crown feathers. P. o. flavotinctus has darker and more olive upperparts, more olive underparts, and yellow on the crown. P. o. eisenmanni has much yellower upperparts, a pale yellowish olive breast and yellow belly, and orange to yellow on the crown. P. o. tachirensis has green-tinged upperparts and orange to yellow on the crown. P. o. harterti is a darker olive overall with yellow to golden on the crown.[4]
Distribution and habitat
The subspecies of the olivaceous piculet are found thus:[2][4]
- P. o. dimotus, eastern Guatemala, northern Honduras, and eastern Nicaragua
- P. o. flavotinctus, Costa Rica, Panama, and Colombia's northern Chocó Department
- P. o. olivaceus, Colombia from Sucre Department south in the Andes to Cauca Department and east to Huila Department
- P. o. eisenmanni, the Serranía del Perijá in extreme northwestern Venezuela; possibly in adjacent northern Colombia
- P. o. tachirensis, eastern slope of Colombia's Eastern Andes and adjacent southwestern Venezuela
- P. o. harterti, from southwestern Colombia south through western Ecuador into northwestern Peru.
The olivaceous piculet inhabits a wide variety of landscapes including the edges of rainforest and
Behavior
Movement
The olivaceous piculet is a year-round resident throughout its range.[4]
Feeding
The olivaceous piculet forages on slender branches, stems, and vines, usually from the forest undergrowth to its mid-storey, though sometimes in the canopy. It is typically seen singly, in pairs, or in small family groups and frequently joins
Breeding
The olivaceous piculet's breeding season varies latitudinally, for example from December to May in Costa Rica and February to September in Colombia. Both sexes excavate a nest hole in rotting wood including fence posts, typically within about 2 m (7 ft) of the ground though sometimes as high as 9 m (30 ft). The clutch size is two or three eggs. Both parents incubate the clutch and provision the young. The incubation period is 13 to 14 days and fledging occurs 24 to 25 days after hatch.[4]
Vocalization
The olivaceous piculet's voice is "a high thin chippering trill, often descending in pitch."[6] It also makes a "sharp sibilant 'sst, ssip-ssip' or 'peep'."[4]
