Rufous Cacholote
Pseudoseisura unirufa
Large cinnamon-colored ovenbird with piercing yellow eyes and a long gray crest. Found in gallery forest, near marshes and woodlands; often near human habitations. Mostly forages on the ground, but also in trees; builds a large stick nest. Song is a loud duet: an accelerating series ending with a rattle mixed with “chew” notes.
识别特征
The grey-crested cacholote is 20 to 21 cm (7.9 to 8.3 in) long and weighs 42 to 57 g (1.5 to 2.0 oz). It is a large, crested, furnariid. The sexes have the same plumage. Adults are mostly bright reddish-rufous that is somewhat paler on their underparts. Their crest varies from entirely rufous to almost entirely grayish. The center of their throat has an orange tinge. Their flight feathers have fuscous tips and the ends of the tail feathers lack barbs. Their iris is yellow to buff-yellow, their bill blue-gray to gray with a paler mandible, and their legs and feet olive to greenish gray. Juveniles have a shorter crest than adults and less uniformity in their color. The formerly conspecific Caatinga cacholote is similar but larger and has no gray in its crown.
分类信息
The grey-crested cacholote is monotypic. It was previously considered a subspecies of the Caatinga cacholote (P. cristata) which was then called the rufous cacholote. The two taxa were split following the data in a paper published in 2000. Confusingly, and contrary to the suggestion of the 2000 paper's authors, the South American Classification Committee of the American Ornithological Society, the Clements taxonomy, and some field guide authors call P. unirufa the rufous cacholote.

分布与栖息地
The grey-crested cacholote has a disjunct distribution. One population is found in Beni Department and extreme northwestern Santa Cruz Department of north-central Bolivia. The other is found in southeastern Santa Cruz, Mato Grosso and Mato Grosso do Sul states in Brazil, and in northern Paraguay. The species inhabits gallery forest, woodlands, and seasonally flooded savanna within the Pantanal, and is often found near human dwellings. In elevation it ranges between 300 and 500 m (1,000 and 1,600 ft).

Glittering-bellied Emerald
Chlorostilbon lucidus
Small green hummingbird found in a variety of open and semiopen habitats, such as forest edges, deserts, savannas, and gardens. Visits feeders. Iridescent green body with a forked dark blue tail and dark wings. Males have a black-tipped red bill with a blue throat, while females have a white belly, black mask, and a black bill with a red base.
Rufous-capped Antthrush
Formicarius colma
Resembles a miniature chicken while walking quietly with a cocked tail on the forest floor. Typically shy and very difficult to see. Note the prominent orange-rufous crown that contrasts with its dark brown body. Juveniles have a black mask, a white chin and throat, and a grayish breast. The song is a long trill increasing in volume towards the end, usually delivered from a slightly raised perch such as a fallen log.
Yellow-headed Amazon
Amazona oratrix
Scarce and local large green parrot of tropical lowland savannas and semiopen areas with forest patches and big trees (but often seen in cages). Like many parrots, usually seen in pairs, not mixing with other species. The head of Mexican birds has extensive yellow (less so on immatures) and the bill is pale. Birds in Belize and Honduras have less yellow on the head. This species is often trapped for the pet trade, which means it has been eliminated from much of its historic range.
