Hi folks, Is it possible to seperate the three sub-species of Dunlin regularly occuring in Britain/Ireland: schinzii, alpina and arctica? And if so does anybody know of a web site that covers this, hopefully with photos? Also of particular interest, is it possible to distinguish hudsonia and pacifica, especially as it seems that hudsonia is significantly different (by dna hybridisation) from all other sub-species? Thanks!
