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:

Galapagos Petrel
Pterodroma phaeopygia
Endangered seabird that nests only in Galápagos. Outside the breeding season, it disperses over the eastern Pacific and usually stays far from land. Note distinctive black-and-white pattern on underwing, mostly white underparts, and dark upperparts that extend down through its face to sides of neck; no other seabird found in and near Galápagos shares these features. When seen from above, it appears all dark except for some white around the base of the bill. Almost always encountered at sea, since it travels to and from its highland nesting sites only at night.
River Tyrannulet
Serpophaga hypoleuca
Small, black, gray, and white flycatcher of lowland rivers. Most commonly found on river islands, and sometimes in other riverside vegetation. Tends to perch horizontally, and moves through dense, low vegetation to forage. Much lighter below than the similar, larger Black Phoebe, which is usually found along fast-flowing rivers at higher elevations.
Western Spindalis
Spindalis zena
Uncommon in thickets, forest edge, and gardens, where found mainly at fruiting trees and bushes. Usually in pairs or small flocks, and often quite inconspicuous. Handsome male is unmistakable, with bold head pattern, golden-yellow and dark reddish body plumage, and bold white wing pattern. Female is notably drab, grayish olive overall with a small white mark on the wing, and a ghosting of the male wing pattern.
