Résumé :	Historically, White-billed Diver Gavia adamsii has been regarded as a very rare bird in Britain. However, observations in northwest Scotland in recent years support the view that, in this area at least, White-billed Diver is better regarded as a scarce passage migrant than a rarity. We present the results of intensive searches for this species in the Outer Hebrides during 2003-2007. We speculate that the pre-breeding moult is one important reason why White-billed Divers linger off northwest Scotland in the early spring, before departing for their Arctic breeding grounds.
