Critically Endangered, probably Extinct.
The Eskimo Curlew (aka doughbird) was one of the most numerous shorebirds in North America with a population in the millions. As many as 2 million birds per year were killed near the end of the 19th century. The last confirmed sighting was in 1962 on Galveston Island, Texas. They migrated to the pampas of Argentina in the late summer and returned to Alaska in February.
