Gilded Hummingbird
Hylocharis chrysura
Medium-sized hummingbird with a long, straight bill which is red with a black tip. Deceptively dull-looking, but in the right light has a golden-green back and breast and a bronze tail. Both sexes are similar. Found at forest edges, in light woodlands, plantations, and at feeders.
识别特征
The gilded sapphire is 8 to 10 cm (3.1 to 3.9 in) long and weighs 4 to 5 g (0.14 to 0.18 oz). Both sexes have a medium length, straight, coral red bill with a black tip. Adult males are mostly iridescent golden-green, with a pale rufous chin and a glittering golden-bronze tail. Adult females are almost the same, but duller overall and with a grayish lower belly. Juveniles are like the adult female with buff fringes on the feathers of the head.
分类信息
The names of this species, both English and scientific, have not been settled. The International Ornithological Committee calls it the gilded sapphire (Hylocharis chrysura). The South American Classification Committee of the American Ornithological Society and the Clements taxonomy call it the gilded hummingbird, also with the binomial H. chrysura. BirdLife International's Handbook of the Birds of the World also calls it the gilded hummingbird but with the binomial Amazilia chrysura. The first three systems agree that it shares genus Hylocharis with the rufous-throated sapphire (H. sapphirina). All four agree that it is monotypic.

分布与栖息地
The gilded sapphire is found in northeastern to south central Bolivia, essentially all of Paraguay and Uruguay, central and southeastern Brazil, and northern Argentina. It inhabits open landscapes such as savannah with scattered trees, the edges and clearings of forests, plantations, and gardens. It is most numerous at elevations between 400 and 800 m (1,300 and 2,600 ft). It is regularly found down to 200 m (660 ft) and up to 1,000 m (3,300 ft), and locally even higher.

Cinnamon Attila
Attila cinnamomeus
Medium-sized sluggish flycatcher of riverine and disturbed habitats. Key marks are entirely cinnamon plumage and large-headed, plain-faced appearance; bill seems heavy and is entirely black. Sits still, peering about, before sallying to foliage for insects. Inhabits mid-story and understory, often at forest edge. Found in forest along rivers and oxbow lakes, in abandoned plantations, and at savanna edges, usually near water. Similar to Dull-capped Attila but has dark eyes and different voice. Most common calls are various mournful whistles.

Yellow-browed Seedeater
Crithagra whytii
A chunky medium-sized seedeater, brown above and pale below with heavy streaking. Patches of yellow appear on several parts of the body, including the eyebrows, breast, and edges of the wing and tail feathers. Found locally along forest edges and in moist scrub and bracken. Can be similar to female or immature Yellow-crowned Canary but larger, heavier-billed, and more streaked below, with a different distribution of yellow. Also somewhat similar to Reichard’s Seedeater, but easily distinguished by the yellow markings. The song is a fast-paced and variable mix of twitters and whistles. The most common call is a rising whiny whistle.

White-headed Petrel
Pterodroma lessonii
A large gadfly petrel with a pale white head and a distinctive dark eye-patch. Back is pale gray with darker outer wings, creating an “M” shape on the back. Look for stout black bill and pinkish-colored feet. Breed on Antipodes and Auckland Islands in the New Zealand region and also on subantarctic Indian Ocean and Macquarie Islands. Forages between the subantarctic and Antarctic convergence zones. Three similar species: Soft-plumaged Petrel is smaller with gray-brown head and band on upper breast; Gray Petrel is larger with a smaller, darker head, a pale green bill, and a long neck; and pale morph Kermadec Petrel is smaller, lacks an eye patch, has darker upperparts, and shows white patches under the wing.
