Magellanic Tapaculo
Scytalopus magellanicus
Often heard but rarely seen; a retiring little gray bird of bamboo thickets and other dense shrubbery at forest edges and along streams, mainly in humid areas. Occurs locally in boulders and low scrub, mainly in the Andes. Can move very quickly through bamboo like a mouse. Plumage is slaty gray overall, often with some paler or brownish barring; some birds have a silvery-white cap or a few white head spots. Best told from Dusky Tapaculo, which has a limited range overlap by voice. Also compare with Ochre-flanked Tapaculo.
识别特征
It is a wren-like bird, 10 to 12 cm in length. The bill is slender and black while the legs are pinkish and fairly long. The tail is short and held erect. The plumage is dark-grey with a chestnut tinge to the flanks, undertail and wings. Some birds have a silvery-white patch on the crown. Juvenile birds are brown with dark barring and usually lack white on the crown. The song is loud, staccato and repetitive.
分类信息
The Magellanic tapaculo was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the wagtails in the genus Motacilla and coined the binomial name Motacilla magellanica. Gmelin based his description on the "Magellanic warbler" that had been described in 1783 by the English ornithologist John Latham in his A General Synopsis of Birds. The naturalist Joseph Banks had provided Latham with a water-colour drawing of the bird by Georg Forster who had accompanied James Cook on his second voyage to the Pacific Ocean. The picture is dated 28 December 1774 at Tierra del Fuego. This picture is now the holotype for the species and is held by the Natural History Museum in London. The species is monotypic: no subspecies are recognised.<p>The species was often known as the Andean tapaculo in the past and included a number of subspecies distributed along the Andes. These are now treated as species in their own right, leaving the Magellanic tapaculo with no subspecies although birds in the north of its range are larger and darker and may deserve subspecies status.

分布与栖息地
Its range extends northwards from Tierra del Fuego as far as Valparaíso Region in Chile and San Juan Province in Argentina. Charles Darwin collected a specimen in the Falkland Islands in 1833 or 1834 but there have been no definite records there since. It inhabits dense vegetation near ground-level in forest and woodland where it forages for insects. It often occurs near water and is commonly associated with stands of Chusquea bamboo.

Wattled Curassow
Crax globulosa
Very large black gamebird with a red bill. Males have a white ventral region which is chestnut in females. Strongly associated with riparian environments, especially seasonally flooded forest and river islands, where it is quite arboreal. Now very rare over much of its range because of overhunting.
Short-billed Minivet
Pericrocotus brevirostris
Brilliantly colored and long-tailed inhabitant of the forest canopy. Males are bright red and black, and females are gray and yellow. Both sexes are very similar to their counterparts in other red-and-black minivet species. Males have a simple pattern on the wing that resembles a “V” or a lightning bolt; lacks the extra blotches of the slightly larger Scarlet Minivet. Females have less gray on the head than the females of the otherwise identically colored Long-tailed and Gray-chinned Minivets. Typically intermediate in altitude between Long-tailed and Scarlet Minivets. Gives high thin whistles.
Red-fronted Macaw
Ara rubrogenys
A large and sometimes conspicuous macaw of Bolivia’s interandean dry valleys. This species is critically endangered, but can sometimes be locally common, especially near tall cliffs cut in hillsides by rivers. Often forages in and around agriculture. The only large, green macaw in its range. Fairly similar to Military Macaw, but shows orange fold to leading edge of wing, no bare facial skin, and a dark gray bill. Often noticed by loud, raucous voice.
