White-winged Chough
Corcorax melanorhamphos
Large, black, crow-sized bird with decurved bill and deep red eye. In flight, white in primaries very evident. Struts around in family groups on the ground in open woodland areas around southeastern and eastern Australia. A variety of calls includes a plaintive, descending whistle.
识别特征
White-winged choughs are easily recognised but often mistaken for "crows" (such as the Australian raven). The white-winged chough is a large, black bird—at about 45 cm (18 in) only a little smaller than a raven or a little larger than an Australian magpie—but has red eyes and a finer, slightly down-curved beak, similar to a European chough. These red eyes become swollen and brighter in colour when the bird is excited. In flight the large white patches in the wings are immediately obvious, and explain the descriptive part of their common name.<p>Their calls consist primarily of a grating alarm call and a descending piping call. The latter call is diagnostic for the bird in the wild, being significantly different in timbre and melody to that of other birds sharing their habitat.
分类信息
The white-winged chough was first described by French naturalist Louis Pierre Vieillot in 1817 as Coracia melanorhamphos, other names given include Pyrrhocorax leucopterus by Dutch zoologist Coenraad Jacob Temminck in 1820, and Corcorax australis by French naturalist René Lesson in 1830. before the current name was settled by Gregory Mathews in 1912. The specific epithet is derived from the Ancient Greek words melano- 'black' and rhamphos 'beak'.<p>It is placed in the family known as the mud-nest builders or Corcoracidae, written as Grallinidae in older books before the removal of the genus Grallina to the family Monarchidae. It is one of two remaining species, with the apostlebird (Struthidea cinerea), which differs in appearance but exhibits many behavioural similarities. The mudnest builder family Corcoracidae itself is now placed in a narrower 'Core corvine' group, which contains the crows and ravens, shrikes, birds of paradise, fantails, monarch flycatchers, and drongos.<p>It is only distantly related to the red-billed chough (Pyrrhocorax pyrrhocorax) and Alpine chough (P. graculus), which are members of the crow family Corvidae. The similarities in appearance of dark plumage and downturned bill are the result of convergent evolution.

Olivaceous Piha
Snowornis cryptolophus
A rather dull, olive-colored bird of Andean cloud forest. It has a yellow or whitish eyering, faint streaking on the underparts, and may show some yellow on the bend of the wing. Black crown stripe is usually concealed. It is found at mid-levels inside the forest, and sometimes joins mixed-species flocks. Unlike other pihas, it is usually silent.
Niceforo's Wren
Thryophilus nicefori
Endangered songbird restricted to the western slopes of the northern part of Colombia’s eastern Andes. Note the white spectacles, striped face, and barred wings and tail. Very similar to the widespread Rufous-and-white Wren, but duller brown, lacking rich chestnut tones in the plumage, and its song tends to be faster and higher in pitch. Range is also helpful for ID, since the two species have limited, if any, overlap. Skulks in the understory of dry to semi-humid forest as well as in shady coffee and cacao plantations.
Hodgson's Redstart
Phoenicurus hodgsoni
Male very similar in appearance to Daurian Redstart; note more restricted silver on the forehead and less distinct wing panel. Female’s lack of a white wing patch distinguishes her from female Daurian, and she averages paler than female Black Redstart, with a brighter eye-ring. Blue-fronted Redstart female can be similar; Hodgson’s female is colder-toned with a single dark stripe down the tail instead of Blue-fronted’s inverted “T.” Hodgson’s breeds in hilly and montane open forests and forest edge; descends in the winter, favoring scrubby edge.
