Elsterfaulvogel

Bestimmung

The pied puffbird is 14 to 17 cm (5.5 to 6.7 in) long and weighs 21 to 40 g (0.74 to 1.41 oz). The nominate subspecies is mostly glossy black above and white below. It has a white line from the bill through the eye, white speckles on the crown, a large white spot on the scapulars, and white near the base of the tail and at its end. A broad black band separates the breast from the belly and the flanks are barred black and white. N. t. picatus is larger and darker than the nominate, with less white on the tail feathers. N. t. subtectus is smaller than the nominate, with a narrower breast band, less white spotting on the crown, and grayer flanks with little white barring.

Taxonomie

The pied puffbird was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux from a specimen collected in Cayenne, French Guiana. The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle that was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Bucco tectus in his catalogue of the Planches Enluminées. The pied puffbird is now placed in the genus Notharchus that was introduced by the German ornithologists Jean Cabanis and Ferdinand Heine in 1863. The generic name combines the Ancient Greek nōthēs meaning "sluggish" and arkhos meaning "leader" or "chief". The specific epithet tectus is Latin for "covered" or "concealed".<p>The International Ornithological Committee (IOC) and the Clements taxonomy recognize these three subspecies. However, BirdLife International's Handbook of the Birds of the World (HBW) treats subtectus as a separate species, "lesser pied puffbird".<p>The genus Notharchus was for a time merged into Bucco by some authorities but has generally been restored to its former status.

Verbreitung und Lebensraum

The nominate subspecies of pied puffbird is found in southern Venezuela, the Guianas, and northern Amazonian Brazil as far east as the state of Maranhão. N. t. picatus is found from southeastern Colombia south through eastern Ecuador and Peru into eastern Bolivia and east into west-central Brazil. N. t. subtectus is found from extreme southeastern Nicaragua through Costa Rica and Panama into north central Colombia, and through western Colombia into northwestern Ecuador. The species is generally resident throughout its range, but appears to make some irregular seasonal movements.<p>The pied puffbird inhabits a variety of landscapes from savanna to the interior and edges of tropical evergreen forest. other examples include secondary forest, gallery forest, abandoned clearings, and mangroves. It tends to prefer the canopy and subcanopy. In Costa Rica it appears to shun primary forest, occurring in more open landscapes up to an elevation of 300 m (980 ft). Elsewhere it occurs as high as 1,000 m (3,300 ft).
