Compared to other groups of birds (such as gulls), only a few species of shorebirds are known or suspected to hybridise, but nonetheless, these hybrids occur quite frequently in some cases.
A similar bird was collected in 1981 at Stockton, New South Wales, Australia.
[9][10] In Europe an apparent hybrid between the dunlin and the purple sandpiper (Calidris maritima) has turned up.
The "avostilt" or "stavocet" is a hybrid between black-necked stilt (Himantopus mexicanus) and American avocet (Recurvirostra americana), occasionally found in California.
[14] One such bird was accidentally bred in the San Francisco Zoo in 1971 and lived at least until 1974.
