Draft Version Target Shorebird Species List
Draft Version Target Shorebird Species List The target species list (species to be surveyed) should not change over the course of the study, therefore determining the target species list is an important project design task. Because waterbirds, including shorebirds, can occur in very high numbers in a census area, it is often not possible to count all species without compromising the quality of the survey data. For the basic shorebird census program (protocol 1), we recommend counting all shorebirds (sub-Order Charadrii), all raptors (hawks, falcons, owls, etc.), Common Ravens, and American Crows. This list of species is available on our field data forms, which can be downloaded from this site, and as a drop-down list on our online data entry form. If a very rare species occurs on a shorebird area survey, the species will need to be submitted with good documentation as a narrative note with the survey data. Project goals that could preclude counting all species include surveys designed to search for color-marked birds or post- breeding season counts of age-classed bird to obtain age ratios for a species. When conducting a census, you should identify as many of the shorebirds as possible to species; sometimes, however, this is not possible. For example, dowitchers often cannot be separated under censuses conditions, and at a distance or under poor lighting, it may not be possible to distinguish some species such as small Calidris sandpipers. We have provided codes for species combinations that commonly are reported on censuses. Combined codes are still species-specific and you should use the code that provides as much information as possible about the potential species combination you designate. -
The World's First Known Juvenile Cox's Sandpiper
British Birds VOLUME 81 NUMBER 6 JUNE 1988 The World's first known juvenile Cox's Sandpiper P. A. Buckley or once, the North Americans have beaten the British by being first Fto find a spectacular vagrant Asiatic shorebird away from the Alaskan out-islands.1 This time we outdid everyone, producing a juvenile Cox's Sandpiper Calidris paramelanotos in Massachusetts. This individual, depicted in colour in plate 145, is not only the first of this recently described species from the Western Hemisphere, but also only the second away from its Australian wintering grounds (an adult was reported from Hong Kong in spring 1987: Brit. Birds 80: 391). The firsts continue, however, for, until this individual, Cox's juvenile plumage was unde- scribed, and, until this photograph, there have been, to my knowledge, no published colour photographs of Cox's Sandpiper in any plumage, let alone that of a juvenile. I am exceedingly grateful to the bird's discoverer, Mark Kasprzyk, for much background information, and to Simon Perkins, for permission to reproduce here his splendid colour photograph. This bird was first mist-netted at night, on 15th September 1987, at Duxbury Beach, a long barrier spit separating Plymouth Bay (where the Mayflower Pilgrims landed in 1620) from Cape Cod Bay/Atlantic Ocean waters. It was ringed as a Pectoral Sandpiper C. melanotos (understandable, at 03.00 hours), but photographed in the hand nonetheless, carefully measured, and then released. Nagging identification doubts soon set in, and efforts to relocate the bird were successful by daylight on 15th. Several observers examined it at close range over the next few days, and it went on the Massachusetts rare bird telephone-tape, finally, as an adult 1 This is actually not the first, truth to tell. -

Cover: Shorebirds and seabirds of the Pilbara coast and islands The Pilbara coast and islands, including the Exmouth Gulf, provide important refuge for a number of shorebird and seabird species. For migratory shorebirds, sandy spits, sandbars, rocky shores, sandy beaches, salt marshes, intertidal flats and mangroves are important feeding and resting habitat during spring and summer, when the birds escape the harsh winter of their northern hemisphere breeding grounds. Seabirds, including terns and shearwaters, use the islands for nesting. For resident shorebirds, including oystercatchers and beach stone-curlews, the islands provide all the food, shelter and undisturbed nesting areas they need. What is a shorebird? Shorebirds, also known as ‘waders’, are a diverse group of birds mostly associated with wetland and coastal habitats where they wade in shallow water and feed along the shore. This group includes plovers, sandpipers, stints, curlews, knots, godwits and oystercatchers. Some shorebirds spend their entire lives in Australia (resident), while others travel long distances between their feeding and breeding grounds each year (migratory).

Seven Deadly Stints and their Friends An Introduction to Calidris Sandpipers – Part 1 Jon L. Dunn Larry Sansone photos 13 October 2020 Los Angeles Birders Genus Calidris – Composed of 23 species the largest genus within the large family (94 species worldwide, 66 in North America) of Scolopacidae (Sandpipers). – All 23 species in the genus Calidris have been found in North America, 19 of which have occurred in California. – Only Great Knot, Broad-billed Sandpiper, Temminck’s Stint, and Spoon-billed Sandpiper have not been recorded in the state, and as for Great Knot, well half of one turned up! Genus Calidris – The genus was described by Marrem in 1804 (type by tautonymy, Red Knot, 1758 Linnaeus). – Until 1934, the genus was composed only of the Red Knot and Great Knot. – This genus is composed of small to moderate sized sandpipers and use a variety of foraging styles from probing in water to picking at the shore’s edge, or even away from water on mud or the vegetated border of the mud. – As within so many families or large genre behavior offers important clues to species identification. Genus Calidris – Most, but not all, species migrate south in their alternate (breeding) or juvenal plumage, molting largely once they reach their more southerly wintering grounds. – Most species nest in the arctic, some farther north than others. Some species breed primarily in Eurasia, some in North America. Some are Holarctic. – The majority of species are monotypic (no additional recognized subspecies).

One, at Seal Sands, Cleveland, on 3rd September 1977, was watched for two hours by a dozen observers before it was identified as a Sharp-tailed. Another, on St Mary's, Isles of Scilly, from 20th to 29th September 1974, although conveniently accompanied by three Pectorals, was overlooked until 25th, by which time the 'four Pectorals' had been observed by many birdwatchers (Flumm 1975). The first three British records, including two summer adults, were first identified as Pectorals, but the skins fortunately survived to be properly * In this paper, 'summer adult' refers to adults in autumn which have not completed the autumn body moult, rather than to 'spring adults' in the bright fresh nuptial plumage acquired in early summer.

Birdobserver15.4 Page180-184 Status of the Curlew Sandpiper in Massachusetts George W. Gove.Pdf
STATUS OF THE CURLEW SANDPIPER IN MASSACHUSETTS by George W. Gove According to Cramp et al. (1983), the breeding range of the Curlew Sandpiper (Calidris ferruginea) extends along the high-arctic, lowland-coastal belt of Northern Siberia. The wintering range is continental Africa and coastally east to Australia and New Zealand. Terres (1980) describes two instances of nesting of the Curlew Sandpiper in North America, both near Barrow, Alaska. In June 1962, nests of two pairs were found, one with three eggs. All eggs in both nests eventually disappeared, taken, it was thought, by marauding Long-tailed and Parasitic jaegers. The second nesting was recorded during the period of July 7-14, 1972. Seven nests were found, of which two, and possibly six, fledged young. Bull (1964) noted that the Curlew Sandpiper is a rare but regular visitor to the east coast of the United States and offered the following hypothesis to explain its occurrence here. Bull proposed that the species may migrate in the fall in an easterly or southeasterly direction from Siberia to Alaska and Canada, eventually reaching the East Coast. This is the route taken by such birds as the Long-billed Dowitcher, the Western Sandpiper, and the Buff-breasted Sandpiper. However, Nisbet has speculated that individuals of the species occurring here make a direct east-west crossing from Europe to North America during migration. Eisenmann has proposed that this species, like the Ruff, is carried across the tropical Atlantic by cyclonic storms or hurricanes while en route to Africa during the fall migration. It would then be seen in spring when it came north from Central and South America with other shorebirds. -
The Status and Occurrence of Curlew Sandpiper (Calidris Ferruginea) in British Columbia
The Status and Occurrence of Curlew Sandpiper (Calidris ferruginea) in British Columbia. By Rick Toochin. Introduction and Distribution The Curlew Sandpiper (Calidris ferruginea) is an elegant species of shorebird that breeds from Taymyr Peninsula in the central Russian Arctic, east along the shorelines of the Arctic Ocean to the coastline of the Chukotka Peninsula in the Russian Far East and has bred in Alaska at Barrow, Oliktok Point and Deadhorse (Hayman et al. 1986, Paulson 2005, O’Brien et al. 2006, West 2008, Brazil 2009). This species is highly migratory with the entire breeding population moving south over a large area of both Europe and Asia to spend the winter from Sub-Sahara Africa, east through coastal regions of India, into Bangladesh, Burma, throughout Southeast Asia and south into Australia and New Zealand (Hayman et al. 1986, Paulson 2005, O’Brien et al. 2006, Brazil 2009). Small groups of birds are also known to winter in Israel, Iraq and occasionally in Western Europe (O’Brien et al. 2006). In North America, the Curlew Sandpiper is a regular vagrant along the Atlantic coast with scattered records for the interior states and Provinces (O’Brien et al. 2006). Along the west coast, the Curlew Sandpiper is a rare species in Alaska where it is considered a casual migrant in the Aleutian Islands and Bering Sea regions as well as the northern regions of the state (West 2008). The Curlew Sandpiper is ever rare in the southeastern regions of the state and is considered accidental in the southern Panhandle region of Alaska (West 2008.) South of Alaska, the Curlew Sandpiper is a rare bird with California having only thirty-three accepted records (Hamilton et al.
