(V) Red-fronted coot, Fulica rufifrons Red-gartered coot, Fulica armillata White-winged coot, Fulica leucoptera Finfoots Order: GruiformesFamily: Heliornithidae Heliornithidae is a small family of tropical birds with webbed lobes on their feet similar to those of grebes and coots. Sungrebe, Heliornis fulica Plovers Order: CharadriiformesFamily: Charadriidae The family Charadriidae includes the plovers, dotterels, and lapwings. They are small to medium-sized birds with compact bodies, short thick necks, and long, usually pointed, wings. They are found in open country worldwide, mostly in habitats near water. American golden-plover, Pluvialis dominica Black-bellied plover, Pluvialis squatarola Tawny-throated dotterel, Oreopholus ruficollis Pied lapwing, Vanellus cayanus Southern lapwing, Vanellus chilensis Rufous-chested dotterel, Charadrius modestus Semipalmated plover, Charadrius semipalmatus Wilson's plover, Charadrius wilsonia Collared plover, Charadrius collaris Two-banded plover, Charadrius falklandicus Oystercatchers Order: CharadriiformesFamily: Haematopodidae The oystercatchers are large and noisy plover-like birds, with strong bills used for smashing or prising open molluscs. American oystercatcher, Haematopus palliatus Avocets and stilts Order: CharadriiformesFamily: Recurvirostridae Recurvirostridae is a family of large wading birds which includes the avocets and stilts. The avocets have long legs and long up-curved bills. The stilts have extremely long legs and long, thin, straight bills. Black-necked stilt, Himantopus mexicanus Thick-knees Order: CharadriiformesFamily: Burhinidae The thick-knees are a group of largely tropical waders in the family Burhinidae. They are found worldwide within the tropical zone, with some species also breeding in temperate Europe and Australia. They are medium to large waders with strong black or yellow-black bills, large yellow eyes, and cryptic plumage. Despite being classed as waders, most species have a preference for arid or semi-arid habitats. Double-striped thick-knee, Burhinus bistriatus Sheathbills Order: CharadriiformesFamily: Chionidae The sheathbills are scavengers of the Antarctic regions. They have white plumage and look plump and dove-like but are believed to be similar to the ancestors of the modern gulls and terns. Snowy sheathbill, Chionis alba Sandpipers Order: CharadriiformesFamily: Scolopacidae Scolopacidae is a large diverse family of small to medium-sized shorebirds including the sandpipers, curlews, godwits, shanks, tattlers, woodcocks, snipes, dowitchers, and phalaropes. The majority of these species eat small invertebrates picked out of the mud or soil. Variation in length of legs and bills enables multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.
