Charadriiformes (Charadrius being Latin for "plover") is the taxonomic order to which the waders, gulls, and auks belong.
[10] The feathers of the great auk made excellent pillows, and egg collectors were so successful in their hobby that the last specimen in Britain was seen in 1840 on Stac an Armin, Scotland.
The Javan lapwing, for example, has not had a confirmed sighting since 1940, but unconfirmed reports continue to give hope that the last individual has yet to die.
[13] The last confirmed sightings of the Eskimo curlew were in the early 1980s, but scientists would rather not issue a formal declaration of extinction until surveying of all potential breeding locations is completed.
[16] A species' continued existence does not necessarily mean the bird can be salvaged, as it may have already passed the minimum viable population.
