Sixteen shorebird species have been reclassified to larger menace classes as the worldwide inhabitants of migratory shorebirds internationally noticed a considerable decline, in keeping with the newest replace to the IUCN Pink Checklist of Threatened Species.
Conservation partnership BirdLife Worldwide, which helps study the standing of the world’s birds for the IUCN Pink Checklist, reassessed round half of the 254 species of shorebirds the group presently screens, for 2024, in keeping with Ian Burfield, BirdLife Worldwide’s world science coordinator.
The reassessment was prompted by a examine printed final yr that confirmed steep declines in lots of shorebird species in North America, Burfield informed Mongabay by way of electronic mail.
“[B]ut because it solely coated a part of their world populations, we needed to supply equal information from elsewhere … to supply a world image, earlier than making use of the IUCN Pink Checklist standards to reassess their standing,” Burfield mentioned. “Most species didn’t want recategorizing, however of people who did, just about all have deteriorated.”
After the newest reassessment, seven of the 16 shorebird species had been categorized as “close to threatened” and 9 are actually “susceptible” to extinction as they skilled world inhabitants declines of 20-40% over three generations.
BirdLife Worldwide mentioned in a press release that migratory birds are particularly in danger as they observe particular migration flyways or routes and cease alongside the best way to relaxation and feed at sure websites that now face threats like habitat loss and local weather change impacts.
“Whereas many of those shorebirds stay quite a few and are nonetheless generally encountered alongside their flyways, new analyses of information from long-term monitoring schemes reveal that the worldwide populations of some species have declined by greater than a 3rd in current a long time,” Burfield mentioned within the assertion.
Amongst people who have now been moved into the next “threatened” class of susceptible are the grey plover (Pluvialis squatarola) and the curlew sandpiper (Calidris ferruginea), each of which breed in numerous elements of the Arctic and migrate globally throughout their nonbreeding seasons. They each face threats from habitat loss and degradation, searching, and local weather change impacts.
The Hudsonian godwit (Limosa haemastica), a big shorebird that breeds in northern Canada and Alaska and migrates to South America throughout its nonbreeding months, can be now thought-about susceptible. The IUCN notes in its evaluation of the species that the chicken’s inhabitants is seeing a “vital decline … most severely famous in numbers recorded at migratory websites in North America.”
BirdLife Worldwide mentioned in its assertion that defending shorebirds can be vital for the coastal communities that rely upon the identical habitats because the birds.
‘The perilous declines of migratory birds are an indication that the integrity of flyways is deteriorating,” Burfield mentioned. “Dropping the community of habitats that migratory birds rely upon to relaxation and feed throughout their lengthy journeys may have extreme penalties for the hundreds of thousands of those that depend on these websites, in addition to the birds.”
