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. -
The Occurrence and Identification of Red-Necked Stint in British Columbia Rick Toochin (Revised: December 3, 2013)
The Occurrence and Identification of Red-necked Stint in British Columbia Rick Toochin (Revised: December 3, 2013) Introduction The first confirmed report of a Red-necked Stint (Calidris ruficollis) in British Columbia was an adult in full breeding plumage found on June 24, 1978 at Iona Island (see Table 1, confirmed records item 1). Recently another older sighting has been uncovered that fits the timing of occurrence for this species in BC and may be valid (see Table 2, hypothetical records item 1). Since the first initial sightings in the late 1970s, there has been a slow but steady increase in observations of this beautiful Asian shorebird in British Columbia and, indeed, across the whole of North America. With an increase in both observer coverage and the knowledge of observers, this species is now known to be of regular, and probably annual, occurrence during fall migration in coastal British Columbia. Additionally, this species is now recorded occasionally during spring migration, indicating that at least a few individuals may be successfully wintering farther south in the western hemisphere. Identification of this species is straightforward when presented with a full breeding- plumaged adult, but identification of birds in juvenile and faded breeding plumage can be very complicated due to the close similarities to other small Calidris shorebirds. This paper describes the distribution and occurrence of the species in B.C., and also examines the similarities of all plumages of Red-necked Stint to species with which it might be confused, most notably Little Stint (C. minuta), Semipalmated Sandpiper (C. pusilla), and Western Sandpiper (C. -
Four Problem Stints
British Birds VOLUME 79 NUMBER 12 DECEMBER 1986 Four problem stints P.J. Grant his paper discusses four records of stints Calidris, the identification of T which has been much debated. All demonstrate the advances which have been made in recent years, especially including the publication of Lars Jonsson's stint paintings (Jonsson & Grant 1984). Reference to that paper will be useful when considering the records described here, as many of the identification points are illustrated and more fully described therein. Several important lessons can be learned from these case histories. The last three in particular demonstrate some of the major pitfalls and difficulties occasionally involved in stint identification, and the high degree of care necessary with some problem stints. Also well demonstrated is the importance to the identification process of good photographic evidence, and it is again urged that positive steps be taken to obtain a representative series of photographs (preferably colour transparencies) when a rare stint is suspected or identified. (Naturally, such steps should always have due regard for bird, habitat and other observers.) 1. Dungeness, Kent, 6th to 9th September 1965 The identity of this bird has been discussed in detail already (Brit. Birds 59: 543-547, plate 79; 72: 264-275, plates 127-129). It is again portrayed here (plate 306). It was originally identified as a Baird's Sandpiper C. bairdii, but [Brit. Birds 79: 609-621, December 1986] 609 610 Four problem stints 306.

Peeps and Related Sandpipers Peeps Are a Group of Diminutive Sandpipers That Are Notoriously Hard to Tell Apart
Peeps and Related Sandpipers Peeps are a group of diminutive sandpipers that are notoriously hard to tell apart. They belong to a subfamily of subarctic and arctic nesting sandpipers known as the Calidridinae (in the sandpiper family, Scolopacidae). During their migrations, when most residents of North America have the opportunity to watch them, mixed flocks of calidridine sandpipers scurry about on mudflats, feeding at the edge of the retreating tide, or swarm aloft, twisting and turning like a dense school of fish. These traits, in a group of birds that look so much alike to start with, give bird watchers nightmares. Fortunately for Alaskans and visitors to our state, Alaska is an excellent location to view and identify calidridine sandpipers. The early summer breeding season is the easiest time of the year to distinguish the various species, not only because they are in breeding plumage and are more approachable than at other times of the year, but also because each species performs a characteristic courtship display with unique vocalizations. For the avid birder, Alaska has the additional attraction of being one of the best places in North America to view exotic Eurasian species. General description: Three peeps are abundant summer residents and breeders in Alaska—the least, semipalmated, and western sandpipers (Calidris minutilla, C. pusilla, and C. mauri) [all lists in order by size]. Another four species from Eurasia may also be seen—the little, rufous-necked, Temminck's, and long-toed stints (“stint” is the British equivalent for peep) (C. minuta, C. ruficollis, C. temminckii, C. subminuta). These seven species range from 5 to 6½ inches (15-17 cm) in length, and weigh from 2/3 to 1½ ounces (17-33 g). -

This page: Great knot. Photos – Grant Griffin/DBCA Photos – Grant page: Great knot. This Greater sand plover. 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).

Group of Sharp-tailed Sandpipers Calidris acuminata (juveniles, front and rear; summer adult, right) and Pectoral Sandpipers C. melanotos (juvenile, left; autumn adult, centre) showing common jizz: flattish back, pot belly, short legs, long rear-end, and smallish head on normally short (though sometimes surprisingly long) neck. Note, however, tendency of Sharp-tailed to appear larger, more portly, shorter-necked and flatter-crowned (Bryan Bland) wo recent summer adult* Sharp-tailed Sandpipers Calidris acuminata Twere identified initially as Pectoral Sandpipers C. melanotos by observers with experience not only of Pectoral but also of juvenile Sharp-tailed. 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.
