Article
Full-text available
Spoon-billed Sandpiper (Calidris pygmeus) is Critically Endangered, declining 9% per year since 2009; although important wintering sites have been identified, little is known about why particular sites are selected. The Gulf of Mottama, Myanmar, supports perhaps 60% of the global population in winter. Our objective was to identify macrohabitat and...

The Endangered Nordmann’s Greenshank Tringa guttifer is one of the most threatened shorebird species in the world. It migrates from eastern Russia to its non-breeding grounds in Southeast Asia, but the distribution of key wintering sites of the species remains poorly known. Here we summarise historical records and recent surveys (2018–2020) of Nord...

Most of the bogs and peatlands of the Moscow Region have been fully transformed by agricultural activities that peaked in the 1920s-1980s. It heavily impacted the river valleys, where the river beds were regulated to ensure the discharge of surplus water from the drainage systems. Due to problems of degradation in the drained peat bogs and the adja...
Article
Mangroves are of great ecological importance that provide multiple ecosystem services, shelter, and habitat for many threatened waterbird species. The mangroves of the Menabe Antimena Protected Area (MANAP) in western Madagascar are among the most extensive remaining on the island. The remaining dryland forests of the MANAP have been subjected to i...

Mangroves are globally threatened, disappearing and degraded. They are lost due to land use changes, mostly agricultural expansion and aquaculture, but also degraded by cutting by villagers and logging and timber extraction for domestic and economic purposes. Extent and conversion of mangroves can usually be estimated by applying remote sensing and...
Article
The Ayeyarwady River, Myanmar, is exceptionally important for waterbirds and other riverine species. Results from mid-winter boat-based surveys in 2017−2019 demonstrated the high conservation value of the river’s avifauna. We recorded a total of 83 waterbird species and 18 species listed as Globally Threatened (7) or Near Threatened (11) under IUCN...

The Spoon-billed Sandpiper Calidris pygmaea is a ‘Critically Endangered’ migratory shorebird. The species faces an array of threats in its non-breeding range, making conservation intervention essential. However, conservation efforts are reliant on identifying the species’ key stopover and wintering sites. Using Maximum Entropy models, we predicted...

The paper presents data on 57 bird species with new information on their status in Southern Chukotka, northern Far Eastern Russia, accumulated in 2000–2019. The main emphasis is made on 33 species, which are found for the first time in this region, and 10 of them for the first time in Chukotka Autonomous Region. These 10 species are the Great White...

From December 2013 to November 2017, eight bird surveys were conducted in the mangroves and mudflats of the Myeik Archipelago, Tanintharyi, Myanmar. The archipelago stretches over ca. 620,000 ha, and its mudflats and mangroves host more than 32,000 migratory waders, gulls and terns. We detected six globally threatened and nine Near-threatened speci...

In October 2018, a satellite-tagged Spoon-billed Sandpiper arrived near Panton Labu city in Seunodon Sub-district, North Aceh District, Aceh Province, Sumatra, Indonesia. The authors located the bird on the ground on 2 November 2018, describe the habitats it used, and make recommendations for future surveys and protection measures in Indonesia.

Much has happened over the past year, of these most are very positive. China’s leading role in the conservation of the species and its habitats with international cooperation still remains a big and positive surprise. However, there were also some setbacks, such as the difficult endeavour to raise young in captivity in Slimbridge, UK.

Over the past 30 years, few bird surveys have been conducted in this area, most of which have taken place across the Myeik archipelago. Notable exceptions are by Htin Hla et al. (2003), who reported on a successful trip to rediscover Gurney’s pitta (Pitta gurneyi), and Inskipp and Inskipp (2003), who provided an annotated bird species list that inc...

Coastal wetlands in Myanmar provide a huge wealth of biodiversity, ranging from Dugongs and Dolphins to migratory waterbirds and marine turtle nesting and feeding sites. They have been underrepresented in conserving biodiversity and wildlife in Myanmar, but recently received much more attention. While land based areas have reached a level of 6% in...

The spoon-billed sandpiper Calidris pygmaea , a migratory Arctic-breeding shorebird, is one of the rarest birds and its population has declined since the 1970s. We surveyed its most important known wintering area in the Upper Gulf of Mottama in Myanmar to estimate recent (2009–2016) changes in its numbers there. The total number of small shorebirds...

The Spoon-billed Sandpiper Calidris pygmaea is one of the most threatened waders in the world. Its population declined dramatically in the decade to 2010, and without concerted conservation action it would now have been on the cusp of extinction. In 2010, conservation organisations from along the species' migratory flyway, supported by organisation...

Bar-headed Geese winter in Myanmar at several sites. Most prominent are the river and floodplains of the Upper Ayeyarwaddy River in the Central drylands of the country as well as the Kaladan River in the northern Rakhine state. This charismatic goose species is intrinsically linked with these two rivers. Every winter, these geese migrate from the H...

The Beach Thick-knee Esacus neglectus is distributed from Northern Australia west through New Guinea, the Philippines, the Indonesian Archipelago and the Malay Peninsula. The total population in Myanmar is not known, but estimated at fewer than 50 breeding pairs. However, no there was no actual proof of breeding until an active nest with a single e...

A recent increase in shorebird surveys and birdwatching activities in SE Asia has enabled the winter distribution of the globally-threatened Nordmann’s Greenshank Tringa guttifer to be determined for the first time. We estimate that 850– 950 birds winter in SE Asia, with most in Thailand and Malaysia and smaller numbers in Myanmar and Sumatra. Hard...

The remarkable and unique bill-shape of the Spoon-billed Sandpiper Calidris pygmaea raises the question as to why such a structure might have evolved. The morphology of the bill was described in detail by Burton (1971) but at the time there was little information on feeding behaviour. Using information we collected during all stages of the annual c...

The spoon-billed sandpiper Calidris pygmaea is a Critically Endangered shorebird that breeds in the Russian arctic and winters in coastal and estuarine habitats in South-east Asia.

We report the record of an individual of Sternula superciliaris (Yellow-billed Tern) in lagoons of Medio Mundo (Vegueta, Huacho, Lima). We hypothesized that this individual crossed the Andes through the Porculla pass, reaching the coast of Lambayeque, heading south later. The presence of coastal wetlands and sea probably gave this individual food a...

Declines in populations of the Critically Endangered Spoon-billed Sandpiper Calidris pygmaeus have been rapid, with the breeding population now perhaps numbering fewer than 120 pairs. The reasons for this decline remain unresolved. Whilst there is evidence that hunting in wintering areas is an important factor, loss of suitable habitat on passage a...

There are an estimated 123 million waterbirds of 153 species breeding in the Arctic. Arctic waterbirds are overall in decline, despite a few taxonomic and regional exceptions. The reasons are often manifold, mainly because all Arctic waterbirds are migratory and are exposed to threats along the flyways that connect almost all global sites, apart fr...
