Pantanal Snipe
Gallinago paraguaiae
Cryptic shorebird found predominately in lowland wet grasslands and flooded fields. Note the long straight bill, white belly with variegated cryptic plumage, and prominent contrasting pale lines on the face and back. In flight, shows a white terminal tail band. Sings a fast repetitive “kek kek kek kek” when on the ground. Also listen for harsh and vibrating “drumming” notes that increase in volume, produced with its tail feathers during flight displays. Not restricted to Paraguay; widespread across much of South America. Formerly known as South American Snipe.
Identification
The adult Pantanal snipe is 26 to 30 cm (10 to 12 in) long. Males weigh about 105 to 140 g (3.7 to 4.9 oz) and females 115 to 185 g (4.1 to 6.5 oz). Females are slightly larger than males but otherwise the same. They have short greenish-gray legs and a very long straight dark bill. Their upperparts have a complex pattern of muted whitish, buffy, rufous, and black on a brown background. Their breast and flanks are buff with black markings and the rest of their underparts whitish. Their face has tan and darker brown stripes that blend into each other.
Taxonomy
The taxonomic history of the New World snipes of genus Gallinago is complicated. What is now the Pantanal snipe has in the past been treated as a subspecies of common snipe (G. gallinago), then as conspecific with what are now the Magellanic snipe (G. magellanica) and the puna snipe (G. andina), and later still as conspecific with only the Magellanic snipe. The South American Classification Committee of the American Ornithological Society, the International Ornithological Committee (IOC), and the Clements taxonomy treat all of them as separate species. However, BirdLife International's Handbook of the Birds of the World (HBW) retains the Pantanal and Magellanic snipes as subspecies of what it calls the South American snipe, with the binomial G. paraguaiae.<p>This article follows the IOC definition of a monotypic G. paraguaiae, the Pantanal snipe.

Range and habitat
The Pantanal snipe is found in almost every mainland South American country; it is absent from Chile and has been found in Ecuador only as a vagrant. It also occurs on Trinidad and the Falkland Islands. However, it is scarce in the Amazon Basin. It inhabits wet grassy savanna. In elevation it is known as high as 1,300 m (4,300 ft) in Venezuela, as high as 2,200 m (7,200 ft) in Peru, and perhaps as high as 2,600 m (8,500 ft) in Bolivia.

Behavior
The Pantanal snipe is essentially sedentary, though some make short movements in winter to find permanent marshes.<p>The Pantanal snipe forages by probing in mud. Their diet of invertebrates is not known in detail but includes insect larvae and earthworms.<p>The Pantanal snipe breeds in most of South America away from the Pacific coast and eastern Brazil, and also on Trinidad and the Falkland Islands. Its breeding season varies geographically across its very large range but has not been fully defined anywhere. The male performs a winnowing display during courtship, flying high in circles and then taking shallow dives to produce a distinctive sound. The typical clutch size is four eggs. The nest, incubation period, and time to fledging are not known.<p>The Pantanal snipe has a very wide variety of vocalizations including a slow chip "kek..kek..kek..kek..kek...", a fast chip "kekkekkekkekkekkekkek", a "short raspy" flight call "..kek......kek...kek-kek...", and a flush call "KEK.kek.kek.....kek.kek...". The chip calls are typically made from the ground or near it such as from a fence post. The species' non-vocal winnowing is made by air flowing over the outer tail feathers during flight. It is described as "a muffled stuttered crescendo series...huhuhuhuhuhu.hu.WHOO..WHOO..WHOO.whu" that lasts about two or three seconds and is repeated about every 10 seconds.

Slaty-backed Forktail
Enicurus schistaceus
The only forktail in its range for which the adult has a gray back and crown; pattern is otherwise similar to that of Black-backed Forktail, which it overlaps partially in range. White on the head is restricted to a thick eyebrow that reaches behind the eye--instead of a full crown--giving it a more small-headed appearance than White-crowned and Spotted forktails. Like other forktails, prefers fast-flowing forested streams.
Cliff Flycatcher
Hirundinea ferruginea
This unmistakable long-winged flycatcher is widespread (though rarely very numerous) throughout much of South America. As the name implies it occurs around cliffs, landslides, and even buildings. Medium size, warm rufous coloration (brightest on the wings), and habitat are distinctive. Some variation across range, with birds in the Andes having more whitish speckling on the face. Compare with Streak-throated Bush-Tyrant, which is larger and has a streaked throat. Usually seen singly or in pairs, perched conspicuously on a snag, rock face, powerline, or building.
Andaman Coucal
Centropus andamanensis
A large, pale-brown, ground-dwelling cuckoo with rusty wings and back. Skulks in bushes and low cover, where it moves clumsily as it searches for small invertebrates, small mammals, and birds to prey on. Like other coucals, it is a cuckoo that builds its own nest. Common throughout its range in gardens, groves, disturbed forests, paddyfields, etc. The song is a series of deep and resonant “hoop” notes.
