Suiriri Flycatcher
Suiriri suiriri
Small flycatcher with a gray head, an olive-brown back, a dark tail, and two grayish wingbars. Subspecies vary in the colour of rump (yellowish or brown) and belly (pale yellow or white). The similar Chapada Flycatcher has a white rump, a yellow belly, a broad whitish tail tip, and a different song and display. Inhabits savanna-like areas with scattered trees and bushes. The song is an easily recognizable series of “pi-chew” notes.
分类信息
The suiriri flycatcher was described by the French ornithologist Louis Pierre Vieillot in 1818 under the binomial name Muscicapa suiriri. The type locality is Puerto Pinasco in Paraguay. It has traditionally been split into two species, the southern Chaco suiriri (S. suiriri) with a white belly and the northern Campo suiriri (S. affinis) with a yellow belly and a contrastingly pale rump, but they interbreed widely where they come into contact, and consequently most authorities now consider them to be part of a single species. It has been suggested that the taxon bahiae from north-eastern Brazil, which is considered a subspecies of S. affinis when that species is split from S. suiriri, actually is the result of hybridization between suiriri and affinis. For the most part it resembles the latter, but it lacks a contrastingly pale rump as the former.<p>The chapada flycatcher is a cryptic species that was included within the suiriri flycatcher until it was described in 2001. While both these species are relatively noisy, only the chapada flycatcher has the distinctive wing-lifting display.<p>Three subspecies are recognised:

分布与栖息地
The suiriri flycatcher occurs in a wide range of semi-open habitats such as Chaco, Caatinga and Cerrado, but generally avoids humid habitats such as the Amazon Rainforest. It ranges from northern Argentina, through Uruguay, Paraguay, eastern Bolivia, to a large part of eastern Brazil, with disjunct populations in southern Guyana, Amapá, and near the lower section of the Amazon River and central Madeira River. These disjunct populations are associated with remnant patches of relatively dry woodland and savanna that largely – or entirely – are surrounded by humid Amazonian forests.<p>It is fairly common locally, and consequently considered to be of least concern by BirdLife International.

Kalinago Wren
Troglodytes martinicensis
Small brownish wren now found only on Dominica; formerly also occurred on Guadeloupe and Martinique. Plumage cinnamon-brown overall, with dark barring on the wings and tail. Lacks white eyebrow. Generally more arboreal than mainland “House Wrens”, occurring in dense brushy woodland throughout the island. Often perches conspicuously when singing, but otherwise fairly secretive. Listen for loud song of chatters and clearer trills, as well as harsh scolding calls.
Kittlitz's Murrelet
Brachyramphus brevirostris
Small, oblong-shaped seabird. Breeding plumage mottled brown; darkness varies, but often shows golden tint. Nonbreeding plumage dark gray above and white below, with a white face and large white wing patch. Nests in crevices in rocky scree slopes, particularly around glaciers; forages in coastal glacial outflows. Similar to Marbled and Long-billed Murrelets, but with shorter bill and white outer tail feathers; breeding birds average paler with speckled back, while nonbreeders show white on face extending above the eye.
Markham's Storm-Petrel
Hydrobates markhami
Small dark seabird of Humboldt Current, although relatively large for a storm-petrel; not seen from shore, but breeds inland in Atacama Desert where it visits colonies at night to avoid predators. Favors warmer waters beyond cooler inshore zone. Plumage all dark except for bold pale bands on upperwing; also note deeply forked tail. Told from similar size Black Storm-Petrel (which favors cooler inshore waters) by bolder pale wing bands, shallower wingbeats, and smaller feet (big feet of Black Storm-Petrel often hang down).
