Agenda Document CMS Distribution: General CONVENTION ON MIGRATORY UNEP/CMS/COP12/Doc.24.1.7 23 May 2017 SPECIES Original: English 12th MEETING OF THE CONFERENCE OF THE PARTIES Manila, Philippines, 23 - 28 October 2017 Agenda Item 24.1.7 ACTION PLAN FOR FAR EASTERN CURLEW (Prepared by the Australian Government) Summary: The Far Eastern Curlew is an endangered migratory shorebird which is included in Appendix I and II of CMS. Resolution 11.14 on a Programme of Work on Migratory Birds and Flyways recommends the development, adoption and implementation of an Action Plan for this species. A task force established under the East Asian – Australasian Flyway Partnership (EAAFP) in 2015 prepared the Action Plan in consultation with Range States, EAAFP Partners, non-government organizations and the research community. The Action Plan was approved by the EAAFP at its meeting of partners held in Singapore in January 2017. The Action Plan identifies key threats and prioritizes actions required to improve the conservation status of the Far Eastern Curlew throughout its range. The Action Plan is submitted to COP12 for adoption with a view to promote immediate implementation. Implementation of the Action Plan will contribute to targets 8, 9 and 10 of the Strategic Plan for Migratory Species 2015-2023. UNEP/CMS/COP12/Doc.24.1.7 ACTION PLAN FOR FAR EASTERN CURLEW Background 1. The Far Eastern Curlew (Numenius madagascariensis) was listed as vulnerable on the IUCN Red List in 2010 and uplisted to endangered in 2015. The species was listed on the Convention on Migratory Species (CMS) Appendix II in 1994 and Appendix I in 2011. The species was designated for Concerted and Cooperative Actions under CMS in 2014. There are currently no international instruments that address conservation issues across the entire range of the species. 2. Resolution 11.14 on the Programme of Work on Migratory Birds and Flyways recommends the development, adoption and implementation of a Species Action Plan (SAP) for the Far Eastern Curlew in East Asia – Australasia, in cooperation with the East Asian-Australasian Flyway Partnership (EAAFP). 3. In 2015 at the 8th Meeting of the Partners of the EAAFP, Australia proposed the establishment of the Far Eastern Curlew Task Force. The proposal was unanimously endorsed and Australia was elected Chair. 4. The primary purpose of the Task Force was to draft and seek Partnership endorsement of the International Single Species Action Plan for the Far Eastern Curlew as the issues facing the species are well suited to the development of targeted conservation actions. Issue 5. The Far Eastern Curlew is endemic to the East Asian – Australasian Flyway and is one of the largest migratory shorebirds in the world. The species breeds in the Russian Federation and China and migrates to the Philippines, Thailand, Palau, Malaysia, Indonesia, Papua New Guinea, Australia and New Zealand for the non-breeding period. 6. Evidence from Australia indicates a severe population decline of 81.4 per cent over 30 years or three generations (5.8 per cent per year). In large part, the observed decline in Far Eastern Curlew numbers stems from ongoing loss of intertidal mudflat habitat at key migration staging sites in the Yellow Sea. If habitat loss and degradation continue, it is expected that the species will continue to decline. 7. The Far Eastern Curlew Task Force, in cooperation with the EAAFP Secretariat, prepared a draft Single Species Action Plan which was sent to all Range States, relevant CMS Parties, EAAFP Partners and the Chairs of relevant EAAFP Working Groups and Task Forces on 5 August 2015. Further targeted consultation occurred on 17 December 2015 with Range States, non-government organizations and researchers. Written consultation with relevant CMS Secretariat staff and COP-Appointed Councillors was undertaken in 2015 and 2016. All comments received were considered and the draft action plan was amended accordingly. 8. The final draft of the Single Species Action Plan was again circulated for comment on 1 April 2016 to all EAAFP Partners. Comments were incorporated as appropriate, and the draft Action Plan was sent to the EAAFP Secretariat for final consideration. Discussion and analysis 9. The Action Plan was presented to the 9th Meeting of Partners to the EAAFP held in Singapore in January 2017. All substantive comments made during plenary were incorporated as appropriate. The Action Plan was unanimously approved by EAAFP Partners. 2 UNEP/CMS/COP12/Doc.24.1.7 10. In order to effectively monitor and report on the implementation of the Action Plan, the Far Eastern Curlew Task Force will be maintained through the EAAFP. 11. The Action Plan is being submitted to COP12 for adoption with the view of promoting immediate implementation. 12. The Action Plan is appended at Annex 1. Consistent with CMS policy concerning language versions of Species Action Plans, the document is produced only in English as its geographic scope does not include any French or Spanish-speaking country. Recommended actions 13. The Conference of the Parties is recommended to: a) adopt the Action Plan contained in Annex 1 through draft Resolution 12.XX on species action plans for birds contained in document UNEP/CMS/COP12/Doc.24.1.11. 3 UNEP/CMS/COP12/Doc.24.1.7/Annex 1 ANNEX 1 INTERNATIONAL SINGLE SPECIES ACTION PLAN FOR THE CONSERVATION OF THE FAR EASTERN CURLEW (Numenius madagascariensis) © Brian Furby Collection Australian Government 4 UNEP/CMS/COP12/Doc.24.1.7/Annex 1 Table of Contents Executive summary ............................................................................................................... 6 Acknowledgments ................................................................................................................. 6 1.

  • Nordmann's Greenshank Population Analysis, at Pantai Cemara Jambi
    Final Report Nordmann’s Greenshank Population Analysis, at Pantai Cemara Jambi Cipto Dwi Handono1, Ragil Siti Rihadini1, Iwan Febrianto1 and Ahmad Zulfikar Abdullah1 1Yayasan Ekologi Satwa Alam Liar Indonesia (Yayasan EKSAI/EKSAI Foundation) Surabaya, Indonesia Background Many shorebirds species have declined along East Asian-Australasian Flyway which support the highest diversity of shorebirds in the world, including the globally endangered species, Nordmann’s Greenshank. Nordmann’s Greenshank listed as endangered in the IUCN Red list of Threatened Species because of its small and declining population (BirdLife International, 2016). It’s one of the world’s most threatened shorebirds, is confined to the East Asian–Australasian Flyway (Bamford et al. 2008, BirdLife International 2001, 2012). Its global population is estimated at 500–1,000, with an estimated 100 in Malaysia, 100–200 in Thailand, 100 in Myanmar, plus unknown but low numbers in NE India, Bangladesh and Sumatra (Wetlands International 2006). The population is suspected to be rapidly decreasing due to coastal wetland development throughout Asia for industry, infrastructure and aquaculture, and the degradation of its breeding habitat in Russia by grazing Reindeer Rangifer tarandus (BirdLife International 2012). Mostly Nordmann’s Greenshanks have been recorded in very small numbers throughout Southeast Asia, and there are few places where it has been reported regularly. In Myanmar, for example, it was rediscovered after a gap of almost 129 years. The total count recorded by the Asian Waterbird Census (AWC) in 2006 for Myanmar was 28 birds with 14 being the largest number at a single locality (Naing 2007). In 2011–2012, Nordmann’s Greenshank was found three times in Sumatera Utara province, N Sumatra.

LEEMAN, Department of Wildlife, Humboldt State University, Arcata, California 95521 (current address: Environmental Science Associates, 8950 Cal Center Drive, Suite 300, Sacramento, California 95826) ABSTRACT. Key ecological insights come from understanding a species’ distribu- tion, especially across several spatial scales. We studied the distribution (uniform, random, or aggregated) at low tide of nonbreeding Long-billed Curlew (Numenius americanus) at three spatial scales: within individual territories (1–8 ha), in the Elk River estuary (~50 ha), and across tidal habitats of Humboldt Bay (62 km2), Cali- fornia. During six baywide surveys, 200–300 Long-billed Curlews were aggregated consistently in certain areas and were absent from others, suggesting that foraging habitats varied in quality. In the Elk River estuary, distributions were often (73%) uniform as curlews foraged at low tide, although patterns tended toward random (27%) when more curlews were present during late summer and autumn. Patterns of predominantly uniform distribution across the estuary were a consequence of ter- ritoriality. Within territories, eight Long-billed Curlews most often (75%) foraged in a manner that produced a uniform distribution; patterns tended toward random (16%) and aggregated (8%) when individuals moved over larger areas.

  • 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).

Abstract Far Eastern Curlew Numenius madagascariensis (Linnaeus, 1766) is Endangered species confined in East Asian Australasian Flyway (EAAF) sites. We compiled and summarized all historical numbers of Far Eastern Curlew in Banyuasin Peninsula, South Sumatra, Indonesia. A total of 30 records were documented from 1984 to 2020. The largest number is 2,620 individuals during the migration period in 1988. Unfortunately, the largest number drop to 1,750 individuals in wintering period in 2008, and then drop to 850 individuals in 2019. The numbers indicate that the population decline by up to 62% in the last 35 years (1984 to 2019).

  • 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.

  • Growth and Development of Long-Billed Curlew Chicks
    April 1973] General Notes 435 Pitelka and Donald L. Beaver critically read the manuscript. This work was con- ducted under the I.B.P. Analysis of Ecosystems-TundraProgram and supported by a grant to F. A. Pitelka from the National ScienceFoundation.--THo•rAs W. CUSTrR, Department o! Zoology and Museum o! 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.
