New report reveals rapid decline in populations of dozens of species worldwide
The International Union for Conservation of Nature (IUCN) has placed 16 shorebird species to higher threat categories in its recent revision of Red List. In fact, the situation for some species is considered extremely worrying, with recorded declines of more than a third of their population.
The shorebirds that are now at risk include species that occur in or pass through our country, such as the Grey Plover, the Dunlin, the Curlew Sandpiper and the Ruddy Turnstone. These species - like millions of other migratory birds - follow specific routes known as flyways and cross numerous countries each year, often stopping to rest and feed. This makes them especially at risk from threats like habitat degradation and loss as well as climate change.
Science has confirmed the serious impacts of the loss of wildlife species, especially birds, whose conservation status is a good indicator of the state of nature. With one in eight bird species threatened with extinction and 60% of bird species in decline globally, diminishing migratory bird populations signal ecosystems in crisis.
“The decline of migratory birds, which connect people across countries and continents, is a powerful symbol of how we are currently failing. This must be the catalyst for governments to back up commitments made two years ago with meaningful action to reverse the catastrophic declines in species populations. This means more action to bolster efforts to recover threatened species, more action to protect and restore more land, freshwater and sea, and more action to transform our food, energy and industrial systems – backed up by the necessary funding”, said Martin Harper, CEO of BirdLife International.
Even more worrying is the fact that, until recently, shorebirds were not often considered to be in high-risk categories, like the vultures or the seabirds. Shorebirds, often seen darting along beaches or feeding on mudflats, are a familiar sight all over the world, including Greece. However, the rate of decline is accelerating, underlining the urgent need for research to diagnose the causes and coordinated conservation action to address them.
"The degradation, fragmentation and loss of habitats essential for the survival of migratory birds could have severe consequences for the millions of people that rely on these sites, as well as the birds. If we further delay galvanizing action to protect and restore them, we are pushing tens if not hundreds of wildlife species to the brink of extinction, which puts our own survival at risk," said Konstantina Ntemiri, Director of the Hellenic Ornithological Society, national partner of BirdLife International.
Just a few weeks after the IUCN 's publication, it was officially announced that the Slender-billed Curlew, a migratory shorebird that once was breeding in western Siberia and wintered in the Mediterranean (incuding our country), is now considered to be EXTINCT according to scientists. This is the first worldwide known extinction of a bird species from continental Europe, North Africa and West Asia.
[1] Except for the 16 migratory shorebird species, the list includes also 129 bird species that are now classified in a different risk category following the latest IUCN revision.
[2] Previously estimated at 50% in BirdLife International’s State of the World’s Birds Report 2022, the percentage of extant bird species with declining global populations is now considered to be 60%, as a result of reassessments by BirdLife International for the 2023 and 2024 IUCN Red List updates.
Species with increased extinction risk include:
- Grey Plover (Pluvialis squatarola), breeds in the Arctic Circle and moves southwards in late summer and autumn to winter, when it is observed in Greece in coastal wetlands and mudflats. Its population has declined by more than 30%, with potential causes including habitat loss and degradation, disturbance and hunting and it is now classified as Vulnerable (VU).
- Dunlin (Calidris alpina), one of the most common and typical shorebirds observed in Greek wetlands in winter and during migration, breeding in tundra and mountain meadows. Its population has declined by at least 20% the last two decades and it is now classified as Near Threatened (NT).- Ruddy Turnstone (Arenaria interpres): breeds on rocky coasts and islands throughout the Arctic Circle and is observed in Greece mainly during the spring migration. Despite its wide distribution and relatively large population, it is estimated to have experienced a population decline of 20-30% over the last 15 years and is now considered Near Threatened (NT).
