IUCN Red List of waders

Recently the IUCN released their new list of Red Data life forms. Among those are a disturbingly high number of waders. About 30% of all wader species are classified as Near Threatened (35), Vulnerable (10), Endangered (10), Critically Endangered (7), Extinct (6) or Data Deficient (1).

Of those considered Critically Endangered it is highly likely that four of them (Jerdon's Courser, Javan Lapwing, Slender-billed and Eskimo Curlew) are now also extinct making the extinct wader list slip into double figures.

It is shocking to see so many of what in my youth were considered common species on the list of Near Threatened species; Northern Lapwing, Bar-tailed Godwit, Black-tailed Godwit, Eurasian Curlew, Curlew Sandpiper, Red Knot, Red-necked Stint and Semipalmated Sandpiper.

If there is any good news to come out of the latest list it is that one of the rarest birds in the world, the St Helena Plover or 'Wirebird' has been moved from Critically Endangered to Vulnerable; this despite the pressures that it has been facing with reduction in sheep grazing and a new airport. This better news is a result of the work being carried out to create new habitat for the bird which seems to have been rather successful as the adult population has grown slightly and has remained higher than 250 individuals since 2007.
