Calidris falcinellus
Broad-billed Sandpiper is a small wader, 16 to 18 cm long, slightly smaller than a dunlin but larger than a little stint. Its bill is longer and straighter than a dunlin's, with the tip distinctly kinked down, and its legs are shorter. Breeding adults have dark brown upperparts with narrow pale fringes, white underparts with blackish breast markings, a pale crown stripe and a distinctive split eyebrow (Wikipedia, general species account). (Wikipedia, general species account).
this was found to be embedded within the wider genus Calidris, into which it was transferred in 2004. Despite its European breeding range, this species is rare on passage in western Europe, due to its south-easterly migration route. This bird's breeding habitat is wet taiga bogs in Arctic northern Scandinavia and Siberia, in two disjunct regions, representing the two subspecies. The pairs nest in a ground scrape, laying four eggs. (Wikipedia, general species account).
