Blackish Oystercatcher
Haematopus ater
Distinctive large chunky shorebird of rocky coasts, adjacent sandy beaches and river mouths. The only all-dark oystercatcher in South America, readily identified by wholly dark plumage, long orange-red bill, thick pinkish legs. Found as singles and pairs, less often small flocks (mainly when roosting), and associates readily with Magellanic and especially American Oystercatchers. Loud piping whistles sound similar to American Oystercatcher.
识别特征
The blackish oystercatcher's plumage is slaty-black with wings and back rather dark brown. The long bill is blood-red and the legs are white. The sexes are similar in appearance. The bird is easily overlooked on a rocky shore, its dark colour blending with the rocks on which it walks as it forages, and it does not draw attention to itself. Its presence, however, can easily be detected by its loud and distinctive warning calls. Its song, when given in duet, consists of an excited chatter of piping whistles. Calls include notes that sound like "pip" and "peeeeyeeee".

分布与栖息地
The blackish oystercatcher is native to the coasts of Argentina, Chile, the Falkland Islands and Peru, and it is a vagrant to Uruguay. Its natural habitats are rocky shores. It feeds in the intertidal zone on rocky shorelines, in rockpools and on pebble beaches. Rarely, it can be found on sandy beaches hunting for mole crabs.

Marbled Murrelet
Brachyramphus marmoratus
Small seabird that breeds in old-growth evergreen forests, sometimes far from the coast. Often in small flocks on coastal waters, where it dives underwater searching for fish. Breeding plumage is dark brown with few contrasting marks; slightly darker cap and blotchy pale belly. Nonbreeding birds are sharply patterned black, white, and gray. Note black cap that extends below the eye, a white collar, and dark grayish pattern on back. Bill is very short and thin. Similar to several other species of murrelets and difficult to distinguish without good views, but note details of face pattern and range.

Gray Falcon
Falco hypoleucos
Seldom-seen pale gray falcon of inland Australia found in arid grassland and woodland habitats, where it sometimes perches high on communication towers. Pale gray upperparts and white underparts, with faint dark streaks below. Legs fully feathered (unlike the long, bare legs of Brown Falcon). In flight, outer upperwing (“hand”) is noticeably darker than the inner wing and back. Wings not as pointed as hobby or Peregrine Falcon. Pale inland Brown Falcons are often misidentified as this species: note that Gray Falcon is unlikely to be seen perched in low bushes or feeding from the ground.

Planalto Slaty-Antshrike
Thamnophilus pelzelni
Small antshrike found in the lower and middle levels of dry forests and at the edge of humid forests. Males are gray overall with a black crown, and white-spotted black wings and tail. Females have a rusty crown, back, and tail, are buff below with white spots on the wings. The song is a loud and long series of around 20 descending notes that accelerate in pace. Doesn’t overlap in range with similar Sooretama Slaty-Antshrike and is told from Variable Antshrike by paler gray plumage in males and richer rufous color in females.
