Migratory Shorebird Factsheet November 2014 Migratory Shorebird Factsheet November 2014 The state of Australia’s migratory shorebirds Thirty-seven species of migratory shorebird visit Australia each year. These species carry out some of the most incredible migrations in the natural world. Each year, they journey many thousands of kilometres along the East Asian-Australasian flyway (Figure 1) between Australia and breeding grounds in the northern hemisphere. Australia’s coastal and freshwater wetlands provide vital habitat for these birds during their non-breeding season. Migratory shorebirds must increase their body weight by up to 70 per cent to build sufficient energy reserves to travel the long distance back to their breeding grounds. During high tide they rest nearby at suitable roosting sites, such as on ocean beaches or in salt marshes bordering coastal wetlands. Figure 1: Key sites on the East-Asian Australasian Flyway. Despite legislative protection and several international conservation agreements, many of these shorebirds have suffered massive population declines in the last 30 years. The population of the Curlew Sandpiper – once one of our most common migratory shorebirds – has declined by up to 80 per cent since the 1980s. Our largest shorebird, the Eastern Curlew, has seen a population crash of almost 50 per cent in the same period. All along the flyway shorebird habitat is being subjected to a broad range of threats: • Ports, industrial, and residential developments are destroying and degrading suitable shorebird habitat. Since European settlement approximately 50% of Australia's non-tidal wetlands have been converted to other uses. • Disturbance from recreational activities such as off-road driving, fishing, jet boats, and off- leash dogs. Excessive disturbance can reduce the birds’ feeding time, or force them to move to less suitable habitat. • Changes to hydrology including changes in flood frequency, salinity, acidity and nutrient levels. • Pollution from agricultural, residential and catchment run-off e.g. excess nutrients, heavy metals, herbicides, pesticides and industrial waste. • Invasive species - introduced plants (e.g. Water Hyacinth) and animals (e.g. Carp, Pigs) • Extractive industries such as fishing, shellfish, seaweed and wrack harvesting • Climate change – expected sea level rises, increased temperatures, and more frequent extreme weather events will further squeeze coastal habitats for shorebirds. While large-scale habitat loss in SE Asia is likely to be the biggest factor contributing to the decline of migratory shorebirds, the incremental loss of habitat in Australia is also likely to be having an impact as many of our resident shorebirds are also declining. Table 1 illustrates some of the threats operating at important shorebird sites around Australia. Table 1: Threats to significant shorebird sites in Australia.

Often, the loss of individual sites is not perceived to be significant because it is assumed that there’s ‘plenty of habitat elsewhere’. However, the cumulative impacts of these threats, including threats operating within Australia, are having a large impact on many shorebird species. Time to take action! BirdLife Australia is deeply concerned by the ongoing decline of Australia’s shorebirds. We are calling on the Australian Government to take action to protect these birds and their habitat by developing: • A strong national wetlands policy that takes the cumulative impacts of multiple threats to our shorebirds into account. • A strategy to engage our international partners in the protection of habitat important to the survival of our shorebirds. • A new Wildlife Conservation Plan for Migratory Shorebirds that makes a strong commitment to the protection of a network of important shorebird habitat in Australia and throughout the East-Asian–Australasian Flyway, with a commitment to no net loss of important habitat. The current Plan has failed to meet its objectives (see Background for more detail). Fortunately – and partly in response to BirdLife Australia and our supporters – the Federal Government released a new draft Wildlife Conservation Plan for Migratory Shorebirds (WCP) in August 2014. The new plan offers significant improvements on the current version - with threat prioritisation, stronger objectives, and recognition of the need for more international cooperation. However, it has some major flaws: • It does not commit Australia to no net loss of important habitat. This is unacceptable; it means that the Government will still allow important shorebird habit to be developed or degraded without adequate compensation (if and where this is even possible). • It fails to take into account cumulative losses – i.e. the collective impacts of multiple threats to our shorebirds. We don’t even have a register of what is being lost. • It ignores the urgent need for updated migratory population estimates and identification of important sites. Decisions are not based on accurate information. • It will not sufficiently increase international cooperation to protect migratory shorebird habitat. Existing international efforts have been inadequate in addressing the rapid destruction of critical staging areas like the Yellow Sea. Unless these flaws are addressed, the WCP will not be effective at addressing the impact of Australia’s development on migratory shorebirds when they visit our shores. The WCP is open for public comment on the Department of the Environment website until 3 December 2014. BirdLife Australia will be making a formal submission to the Department of the Environment and the Federal Environment Minister with our feedback on how the WCP must be strengthened. We strongly encourage you to comment on the plan. Background Information Who are Australia’s shorebirds? Australia regularly supports around 54 species of shorebirds. Of these, 18 shorebird species spend their entire lives within Australia (resident species), although they may make substantial movements within Australia. A further 36 species make regular international movements to Australia from their breeding grounds. Thirty-five of these migratory shorebirds travel thousands of kilometres each year from their northern hemisphere breeding grounds, whereas one species, the Double-banded Plover, migrates in modest numbers from New Zealand in winter. A further 24 species have only been recorded in Australia as irregular rarities and are classified as ‘vagrants’.

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.

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).

  • Species Account
    SPOTTED SANDPIPER Actitis macularius non-breeding visitor, vagrant monotypic Spotted Sandpipers breed across n. N America and winter as far south as c. S America (AOU 1998). The status of this species in the Pacific and the Hawaiian Islands is confused by its similarity to Common Sandpiper, a Eurasian counterpart (Dement'ev and Gladkov 1951c, Cramp and Simmons 1983), that has reached the Hawaiian Islands on at least two occasion and possibly others (David 1991). Records of this pair, unidentified to species, have been reported throughout the Pacific (E 41:115, Clapp 1968a, Pyle and Engbring 1985, Pratt et al. 1987) while confirmed Spotted Sandpipers have been recorded from Clipperton, the Marshall, Johnston, and the Hawaiian Is (Amerson and Shelton 1976, Howell et al. 1993, AOU 1998). David (1991) analyzed records of the two species of Actitis sandpipers in the Southeastern Hawaiian Islands and concluded that, between 1975 and 1989, 6 of 12 birds (1983-1989) could be confirmed as Spotted Sandpipers based on descriptions and photographs while the remaining six (1975-1983) could not be identified. Prior to this, Pyle (1977) listed only the species pair (Spotted/Common Sandpiper) for the Hawaiian Islands. Since this analysis and through the 2000s there have been 25 additional records of Actitis, 18 of which we consider confirmed Spotted Sandpipers while 7 did not include enough descriptive notes to separate them from Common Sandpiper. Because 24 of 37 records in the Southeastern Islands have been confirmed as Spotted Sandpipers and only one has been confirmed as a Common Sandpiper, we assume that the following summary of Actitis sandpipers reflects the status of Spotted Sandpiper, the more expected species in the Southeastern Islands.

  • Population Analysis and Community Workshop for Far Eastern Curlew Conservation Action in Pantai Cemara, Desa Sungai Cemara – Jambi
    POPULATION ANALYSIS AND COMMUNITY WORKSHOP FOR FAR EASTERN CURLEW CONSERVATION ACTION IN PANTAI CEMARA, DESA SUNGAI CEMARA – JAMBI Final Report Small Grant Fund of the EAAFP Far Eastern Curlew Task Force Iwan Febrianto, Cipto Dwi Handono & Ragil S. Rihadini Jambi, Indonesia 2019 The aim of this project are to Identify the condition of Far Eastern Curlew Population and the remaining potential sites for Far Eastern Curlew stopover in Sumatera, Indonesia and protect the remaining stopover sites for Far Eastern Curlew by educating the government, local people and community around the sites as the effort of reducing the threat of habitat degradation, habitat loss and human disturbance at stopover area. INTRODUCTION The Far Eastern Curlew (Numenius madagascariencis) is the largest shorebird in the world and is endemic to East Asian – Australian Flyway. It is one of the Endangered migratory shorebird with estimated global population at 38.000 individual, although a more recent update now estimates the population at 32.000 (Wetland International, 2015 in BirdLife International, 2017). An analysis of monitoring data collected from around Australia and New Zealand (Studds et al. in prep. In BirdLife International, 2017) suggests that the species has declined much more rapidly than was previously thought; with an annual rate of decline of 0.058 equating to a loss of 81.7% over three generations. Habitat loss occuring as a result of development is the most significant threat currently affecting migratory shorebird along the EAAF (Melville et al. 2016 in EAAFP 2017). Loss of habitat at critical stopover sites in the Yellow Sea is suspected to be the key threat to this species and given that it is restricted to East Asian - Australasian Flyway, the declines in the non-breeding are to be representative of the global population.

  • 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.

  • Green Sandpiper Uttering Call of Wood Sandpiper.—With Reference to J
    NOTES Gannets robbing gulls.—On 5th August 1957, I spent the day at sea in Dingle Bay, Co. Kerry, in the trawler "Ros Brin". As soon as trawling operations began, we were accompanied by a few Storm Petrels (Hydrobates pelagicus), Fulmars (Fulmarus glacialis), Great Black-backed Gulls (Larus marinus), Lesser Black-backed Gulls (L. fuscus), and large numbers of Herring Gulls (L. argentatus). During the gutting periods, and especially when any small waste fish were thrown over-board, six to eight Gannets (Sula bassana), would join in the feast. Any fish that sank too deep for the gulls were immediately taken by the Gannets by the normal manner of diving, but on numerous occasions when a gull sitting on the surface had a fish it could not swallow quickly—i.e. small plaice, dabs and other flat fish—one or other of the Gannets would plunge in a shallow-angled frontal dive at the gull, entering the water about two yards away and snatching the fish from the gull's bill on breaking the surface. The fish was swallowed on the surface. This was repeated many times, and the Gannets also frequently fluttered along the water and snatched fish from the bills of other gulls which they passed. On several occasions, too, a Gannet was seen to lunge into the air after a retreating gull that was attempting to rise from the water with a fish; the Gannet "treading water" with wings half-open and neck fully extended upwards in its endeavour to snap the fish from the slowly rising and heavily gorged' gull.
