Upland Sandpiper
Bartramia longicauda
Distinctive sandpiper found in areas with short grass. Frequently seen perched on fence posts or atop small shrubs. Overall patterned buffy-brown with small head, long neck, large eye, and yellow bill with black tip. Long tail and shallow fluttery wingbeats give it a unique look in flight. Song typically given in flight; starts with a soft gurgling trill and ends with a loud whistle that rises and falls. Migrates to South America in the winter, particularly Paraguay and northern Argentina.

分布与栖息地
Even though they are sandpipers, they prefer open country with tall grasses to coastal habitat. They are also found at airports, blueberry farms and abandoned strip mines in the east. Their true core range and habitat is in the northern midwest United States. They breed from eastern Alaska south east of the Rocky Mountains through Montana to northern Oklahoma and then northeast to Pennsylvania, New England and extreme southern Quebec and Ontario. There are also local breeding populations in northeast Oregon and west central Idaho. They winter in northeastern Argentina, Uruguay and southern Brazil. It is an extremely rare vagrant to the South Pacific, with one record each from Australia and New Zealand.

保护状况
The numbers of these birds increased as forests were cleared in the early 19th century, but declined sharply in the late 19th century due to hunting. They are now regularly present in Midwestern North America but populations are scattered in the east.<p>Loss of prairie habitat is a concern. Also, livestock grazing has been found to reduce the number of nests in a field. Controlled burns may benefit this species as they feed on low-growing plants that are more easily spotted after a fire.

Brown Cacholote
Pseudoseisura lophotes
Large ovenbird with rusty-brown plumage, a long crest, and piercing yellow eyes. Found in deciduous forest, second growth, and open woodland. Often also encountered in wooded urban areas like gardens and parks, where it mostly forages on the ground. The song is usually given as an unmusical duet.
Sapphire-rumped Parrotlet
Touit purpuratus
Small parrot of lowland rainforest and savanna regions; more common in areas with sandy soils, but rarely seen well. Usually in small flocks that fly rapidly through or above canopy, settling into trees where they essentially disappear. When perched, best identified by small size and combination of blue rump and red outer tail feathers. In flight, gives drawn-out, complaining call note, very unlike calls of other parrots in range. Feeds on fruit.
Brown-throated Wattle-eye
Platysteira cyanea
Small black-and-white bird with a bright red patch of bare skin above the eye. Males have a black breast band, and females a brown throat. Found in thick woodland, gallery forest, and mangroves. The song is usually given as a duet: a descending series of melancholy whistles from the male, and lower rasping notes from the female. Similar to Black-throated Wattle-eye, but shows a white slash on the wing, and the female has a brown rather than white throat. Separated from batises by the red wattle and, in females, by the brown throat.
