The Broad-billed Sandpiper (Limicola falcinellus) is a small wading bird. It is the only member of the genus Limicola; some have proposed that it should be placed in the genus Erolia with the "stint" sandpipers, but more recent research (Thomas et al., 2004) suggests that it is should rather go into the genus Philomachus with the ruff and possibly the Sharp-tailed Sandpiper; it certainly is a fairly unusual calidrid.
Broad-billed Sandpipers are small waders, slightly smaller than the Dunlin, but with a longer straighter bill, and shorter legs. The breeding adult has patterned dark grey upperparts and white underparts with blackish markings on the breast. It has a pale crown stripe and supercilia.
In the boreal winter, they are pale grey above and white below, like a winter Dunlin, but retaining the head pattern. Juveniles have backs, similar to young Dunlin, but the white flanks and belly and brown-streaked breast are distinctive.
