The plover is a small sand-colored, sparrow-sized shorebird that nests and feeds along coastal sand and gravel beaches in North America. The adult has yellow-orange-red legs, a black band across the forehead from eye to eye, and a black stripe running along the breast line. This chest band is usually thicker in males during the breeding season, and it is the only reliable way to tell the sexes apart. The bird is difficult to see when it is standing still, as it blends well with open, sandy beach habitats. It typically runs in short, quick spurts and then stops.
The red knot is a medium-sized shorebird which breeds in tundra and the Arctic Cordillera in the far north of Canada, Europe, and Russia. It is a large member of the Calidris sandpipers, second only to the great knot. Six subspecies are recognised.
The bar-tailed godwit is a large wader in the family Scolopacidae, which feeds on bristle-worms and shellfish on coastal mudflats and estuaries. It has distinctive red breeding plumage, long legs, and a long upturned bill. Bar-tailed godwits breed on Arctic coasts and tundra from Scandinavia to Alaska, and overwinter on coasts in temperate and tropical regions of the Old World, Australia, and New Zealand. The migration of the subspecies Limosa lapponica baueri across the Pacific Ocean from Alaska to New Zealand is the longest known non-stop flight of any bird, and also the longest journey without pausing to feed by any animal. The round-trip migration for this subspecies is over 29,000 km (18,020 mi).
![Ruff (bird) A medium-sized migratory wading bird that breeds in northern [[Palearctic|Eurasia]]](https://upload.wikimedia.org/wikipedia/commons/thumb/5/5f/Philomachus_pugnax_-Diergaarde_Blijdorp-8c.jpg/320px-Philomachus_pugnax_-Diergaarde_Blijdorp-8c.jpg)
The ruff is a medium-sized wading bird that breeds in marshes and wet meadows across northern Eurasia. This highly gregarious sandpiper is migratory and sometimes forms huge flocks in its winter grounds, which include southern and western Europe, Africa, southern Asia and Australia.
A flyway is a flight path used by large numbers of birds while migrating between their breeding grounds and their overwintering quarters. Flyways generally span continents and often pass over oceans. Although applying to any species of migrating bird, the concept was first conceived and applied to waterfowl and shore birds. The flyways can be thought of as wide arterial highways to which the migratory routes of different species are tributaries. An alternative definition is that a flyway is the entire range of a migratory bird, encompassing both its breeding and non-breeding grounds, and the resting and feeding locations it uses while migrating. There are four major north–south flyways in North America and six covering Eurasia, Africa and Australasia.
Eighty Mile Beach, also spelled Eighty-mile Beach or 80-mile Beach, lies along the north-west coast of Western Australia about half-way between the towns of Broome and Port Hedland. It is a beach some 220 kilometres (140 mi) in length, forming the coastline where the Great Sandy Desert approaches the Indian Ocean. It is one of the most important sites for migratory shorebirds, or waders, in Australia, and is recognised as a wetland of international importance under the Ramsar Convention on Wetlands.
The spoon-billed sandpiper is a small wader which breeds in northeastern Russia and winters in Southeast Asia. This species is highly threatened, and it is said that since the 1970s the breeding population has decreased significantly. By 2000, the estimated breeding population of the species was 350–500.
The Maranhão mangroves is a mangrove ecoregion of northern Brazil. It supports half of the shorebird population of the country. The combination of flat land, heavy rainfall and high tides causes the mangroves to extend up to 40 kilometres (25 mi) inland, where they are interspersed with other rainforest species.
The Kentish plover is a small cosmopolitan shorebird of the family Charadriidae that breeds on the shores of saline lakes, lagoons, and coasts, populating sand dunes, marshes, semi-arid desert, and tundra. Both male and female birds have pale plumages with a white underside, grey/brown back, dark legs and a dark bill, however additionally the male birds also exhibit very dark incomplete breast bands, and dark markings either side of their head, therefore the Kentish plover is regarded as sexually dimorphic
The Anahuac National Wildlife Refuge (NWR) is a wildlife conservation area along the coast of Texas (USA), west of the town of High Island, Texas. It borders East Bay, part of the Galveston Bay complex, behind Bolivar Peninsula at the Gulf of Mexico.
The Quill Lakes is a wetland complex in Saskatchewan, Canada that encompasses the endorheic basin of three distinct lake wetlands: Big Quill Lake, Middle Quill Lake and Little Quill Lake. On May 27, 1987, it was designated a wetland of international importance via the Ramsar Convention. It was the first Canadian site in the North American Waterfowl Management Plan, is a site in the International Biological Programme and Saskatchewan Heritage Marsh Program, and was designated a Western Hemisphere Shorebird Reserve Network site of International significance in May, 1994. The site is an important staging and breeding area for spring and fall migration of shorebirds. The site qualifies as an Important Bird Area for its globally and nationally significant migratory and breeding populations of more than a dozen species of birds.
Shepody Bay is a tidal embayment, an extension of the Bay of Fundy in New Brunswick, Canada, which consists of 77 square kilometres (30 sq mi) of open water and 40 km2 (15 sq mi) of mudflats, with 4 km2 (1.5 sq mi) of saline marsh on the west, and eroding sand and gravel beaches covering an area of approximately 1 km2 (0.39 sq mi) on the eastern shore. The intertidal mudflats "support internationally important numbers of the crustacean Corophium volutator, the principal food source for millions of fall migrating shorebirds".
Mary's Point is a 12 square kilometres (4.6 sq mi) wetland in Albert County, New Brunswick, Canada. It is at the head of the Bay of Fundy, just outside the small community of Harvey and approximately 40 km (25 mi) south of Moncton. Designated a Ramsar wetland of international importance on May 24, 1982, it is also part of the Fundy biosphere reserve established in 2007, which also contains the Shepody Bay wetland. It was also the first Canadian site in the Western Hemisphere Shorebird Reserve, as part of the Bay of Fundy Hemisphere Shorebird Reserve. It is within the Shepody Bay National Wildlife Area, which is administered by the Canadian Wildlife Service.
The San Luis National Wildlife Refuge Complex is located in the northern San Joaquin Valley, within Merced County and Stanislaus County of California. The complex, with four federal National Wildlife Refuges, is managed by the U.S Fish & Wildlife Service.
George C. Reifel Migratory Bird Sanctuary is a protected area in Delta, British Columbia, Canada, and is part of the Fraser River estuary, designated a site of Hemispheric Importance by the Western Hemisphere Shorebird Reserve Network.
Grays Harbor National Wildlife Refuge is located within Grays Harbor, at the mouth of the Chehalis River, which makes up the second largest watershed in Washington. It is one of four major staging areas for migrating shorebirds in the Pacific Flyway. Up to one million shorebirds gather here in spring and fall to feed and rest.
Long Lake National Wildlife Refuge, located in south-central North Dakota, was established in 1932 as a migratory bird refuge by President Herbert Hoover. The 22,300-acre (90 km2) refuge consists of a 15,000-acre (61 km2) saline basin that is 18 miles (29 km) long and is appropriately named "Long Lake." Long Lake is relatively shallow; it is normally 3–4 feet (0.91–1.22 m) deep. During extended wet periods, Long Lake reaches depths up to 7 feet (2.1 m).
The Forrestdale and Thomsons Lakes Ramsar Site comprises two separate nature reserves, totalling 754 ha in area, protecting two shallow fresh to brackish, seasonal lakes in a suburban and agricultural landscape in south-western Western Australia. It lies in the Swan Coastal Plain bioregion and is used mainly for birdwatching and walking. The site is recognised as being of international importance under the Ramsar Convention on Wetlands, under which it was designated Ramsar Site 481 on 7 June 1990.
Cabbage Tree Island, also known as the John Gould Nature Reserve, is a protected nature reserve and uninhabited continental island lying 1.4 km (0.87 mi) off the mouth of Port Stephens on the coast of New South Wales, Australia. The 30 ha (74-acre) reserve and island is named for the Cabbage-tree Palms in the two gullies on the island's western side which are the nesting site of Goulds petrel. It is the principal breeding site of the nominate subspecies of the threatened Gould's petrel and, with the nearby Boondelbah Island where there is also a small colony, has been classified by BirdLife International as an Important Bird Area.
