  • The First Record of Far Eastern Curlew (Numenius Madagascariensis) in British Columbia
    The First Record of Far Eastern Curlew (Numenius madagascariensis) in British Columbia. By Rick Toochin and Don Cecile. Submitted: April 15, 2018. Introduction and Distribution The Far Eastern Curlew (Numenius madagascariensis) is the largest migratory shorebird in the world. This species is found only along the East Asian–Australasian Flyway. The Far Eastern Curlew breeds on open mossy or transitional bogs, moss-lichen bogs and wet meadows, and on the swampy shores of small lakes in Siberia and Kamchatka in Russia, as well as in north-eastern Mongolia and China (Hayman et al. 1986, del Hoyo et al. 1996). The Yellow Sea of the Republic of Korea and China is a vitally important stopover site on migration. This species is also a common passage migrant in Japan and Indonesia, and is occasionally recorded moving through Thailand, Brunei, Bangladesh, Vietnam, Philippines, Malaysia and Singapore (O’Brien et al. 2006). During the winter a few birds occur in southern Republic of Korea, Japan, China, and Taiwan (Brazil 2009, EAAFP 2017). About 25% of the population is thought to winter in the Philippines, Indonesia and Papua New Guinea. Most birds, approximately 73% or 28,000 individuals, spend the winter in Australia, where birds are found primarily on the coast of all states, particularly the north, east and south-east regions including Tasmania (Bamford et al. 2008, BirdLife 2016). In the early 2000’s, the global population of the Far Eastern Curlew was estimated at 38,000 individuals (BirdLife 2016). Unfortunately due to the fact that the global population is declining, the true population size is likely to be much smaller, and may not exceed 20,000 individuals (BirdLife 2016).

  • 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.

Vertebrate Zoology, University o! California, Berkeley,California 94720. Accepted9 May 72. Growth and development of Long-billed Curlew chicks.--Compared with the altricial nestlings of passerinesand the semiprecocialyoung of gulls, few studies of the growth and developmentof the precocialchicks of the Charadrii have been made (Pettingill, 1970: 378). In Europe, yon Frisch (1958, 1959) describedthe develop- ment of behavior in 14 plovers and sandpipers. Davis (1943) and Nice (1962) have reported on the growth of Killdeer (Charadriusvociferus), Nice (1962) on the Spotted Sandpiper (Actiris macularia), and Webster (1942) on the growth and development of plumages in the Black Oystercatcher (Haematopus bachmani). Pettingill (1936) studiedthe atypical AmericanWoodcock (Philohelaminor). Among the curlews, Genus Numenius, only the Eurasian Curlew (N. arquata) has been studied (von Frisch, 1956). Becauseof the scant knowledgeabout the development of the youngin the Charadriiand the scarcityof informationon all aspectsof the breeding biology of the Long-billed Curlew (N. americanus) (Palmer, 1967), I believe that the following data on the growth and development of Long-billed Curlew chicks are relevant. I took four eggs,one being pipped, from a nest 10 miles west of Brigham City, Box Elder County, Utah, on 24 May 1966. One egg was preservedimmediately for additional study, the others I placed in a 4' X 3' X 2' cardboard box with a 60-watt lamp for warmth in a vacant room in my home until they hatched.

Senner Received 6 February 2006; final revision accepted 21 March 2006 Cotinga 26(2006): 39–42 Hay poca información sobre las rutas de migración y el uso de los sitios de la costa peruana por chorlos nearcticos.

En Virilla yo observí más de 2.000 individuales de 23 especios de chorlos nearcticos y el primer registro de Numenius americanus de Peru, la concentración más grande de Limosa fedoa en Peru, y una concentración excepcional de Limosa haemastica. La combinación de esas observaciones y los resultados de un estudio anterior en el invierno boreal sugiere la posibilidad que Virilla sea muy importante para chorlos nearcticos en Peru. Las observaciones, también, demuestren la necesidad hacer más estudios en la costa peruana durante el año entero, no solemente durante el punto máximo de la migración de chorlos entre septiembre y noviembre.

  • TESTING a MODEL THAT PREDICTS FUTURE BIRD LIST TOTALS by Robert W. Ricci Introduction One of the More Enjoyable Features of Bird
    TESTING A MODEL THAT PREDICTS FUTURE BIRD LIST TOTALS by Robert W. Ricci Introduction One of the more enjoyable features of birding as a hobby is in keeping bird lists. Certainly getting into the habit of carefully recording our own personal birding experiences paves the way to a better understanding of the birds around us and prepares our minds for that chance encounter with a vagrant. In addition to our own field experiences, we advance our understanding of bird life through our reading and fraternization with other birders. One of the most useful ways we can communicate is by sharing our bird lists in Christmas Bird Counts (CBC), breeding bird surveys, and in the monthly compilation of field records as found, for example, in this journal. As important as our personal observation might be, however, it is only in the analysis of the cumulative experiences of many birders that trends emerge that can provide the substance to answer important questions such as the causes of vagrancy in birds (Veit 1989), changes in bird populations (Davis 1991), and bird migration patterns (Roberts 1995). Most birders, at one time or another, have speculated about what new avian milestones they will overtake in the future. For example, an article in this journal (Forster 1990) recorded the predictions of several birding gurus on which birds might be likely candidates as the next vagrants to add to the Massachusetts Avian Records Committee roster of 451 birds. Just as important as predictions of which birds might appear during your field activities are predictions of the total number of birds that you might expect to encounter.

  • The Potential Breeding Range of Slender-Billed Curlew Numenius Tenuirostris Identified from Stable-Isotope Analysis
    Bird Conservation International (2016) 0 : 1 – 10 . © BirdLife International, 2016 doi:10.1017/S0959270916000551 The potential breeding range of Slender-billed Curlew Numenius tenuirostris identified from stable-isotope analysis GRAEME M. BUCHANAN , ALEXANDER L. BOND , NICOLA J. CROCKFORD , JOHANNES KAMP , JAMES W. PEARCE-HIGGINS and GEOFF M. HILTON Summary The breeding areas of the Critically Endangered Slender-billed Curlew Numenius tenuirostris are all but unknown, with the only well-substantiated breeding records being from the Omsk prov- ince, western Siberia. The identification of any remaining breeding population is of the highest priority for the conservation of any remnant population. If it is extinct, the reliable identification of former breeding sites may help determine the causes of the species’ decline, in order to learn wider conservation lessons. We used stable isotope values in feather samples from juvenile Slender-billed Curlews to identify potential breeding areas. Modelled precipitation δ 2 H data were compared to feather samples of surrogate species from within the potential breeding range, to produce a calibration equation. Application of this calibration to samples from 35 Slender-billed Curlew museum skins suggested they could have originated from the steppes of northern Kazakhstan and part of southern Russia between 48°N and 56°N. The core of this area was around 50°N, some way to the south of the confirmed nesting sites in the forest steppes. Surveys for the species might be better targeted at the Kazakh steppes, rather than around the historically recog- nised nest sites of southern Russia which might have been atypical for the species. We consider whether agricultural expansion in this area may have contributed to declines of the Slender-billed Curlew population.
