The importance of Icelandic riverplains as breeding habitats for Whimbrels Numenius phaeopus
Capsule: Threatened riverplain habitats in Iceland, which hold a substantial proportion of the world population of Whimbrels, had much higher breeding densities than other habitats but proportion of successful breeders was similar between habitats. Aim: To estimate the conservation value of preferre...
