Buff-necked Ibis
Theristicus caudatus
Stocky ibis. Very similar to Black-faced Ibis but no range overlap. Back and wings mostly gray with black belly and contrasting buffy neck and head. Long decurved bill and pink legs. Usually found in pairs or small groups, in open habitats like pastures and savannas. Often far from water, unlike most other ibis.
识别特征
It has a total length of approximately 75 centimetres (30 in). The neck is buffish, the upperparts are grey, the belly and flight feathers are black, and there is a large white patch in the wings. In flight, where the relatively short legs do not extend beyond the tail (unlike e.g. Eudocimus and Plegadis), the white patch forms a broad white band on the upperwing that separates the black remiges and the grey lesser wing-coverts. The bill and bare skin around the eyes are blackish and the legs are red.
分类信息
The buff-necked ibis was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1781 in his Histoire Naturelle des Oiseaux based on a specimen collected in Cayenne, French Guiana. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which 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 Scolopax caudatus in his catalogue of the Planches Enluminées. The buff-necked ibis is now placed in the genus Theristicus that was erected by the German naturalist Johann Georg Wagler in 1832. The name of the genus is from the Ancient Greek theristikos meaning "of reaping"; the specific epithet is from the Latin caudatus meaning "tailed".<p>Two subspecies are recognised:

Blackish Pewee
Contopus nigrescens
Small, uniformly dark pewee, elusive in the canopy of humid forests, often at higher elevations in Andean foothills but also apparently patchily in Amazonian lowlands. Usually found perching upright at the top of tall trees. Call is a high “peep” like Tropical Pewee, sometimes double-noted.
Ringed Woodpecker
Celeus torquatus
This striking Celeus is widespread across the Amazonian lowlands of northern South America, with a disjunct population in southeast Brazil. Overall rufous with a shaggy crest like most other members of the genus. Distinctive and unlikely to be confused. Some variation across the range: most have extensive black markings on upperparts and belly, but largely unmarked in the northeastern part of range. All birds have solid black breast. Sexes are similar, but males have a red mustache. Occurs in mature forest and edges, often detected by its series of loud, strident whistles.
Makira Cicadabird
Edolisoma salomonis
Male is light powder-gray with darker wing feathers and tail and a dark patch in front of the eye. Female is powder-gray above and vivid reddish below. Prefers primary forest, and appears to avoid secondary growth and scrub. Common call is a loud “chi-beet” or “pity-you.”
