well i have had a good think, hmm its like this, once again it proves that there is no such thing as a typical bird just like humans they all differ if you look hard enough and long enough. i mean how many species are there that we struggle to separate sexes. then you get to such detail of sub species interbreeding etc ( redpolls ) some obvious some not, some not sure, the whole area is a true minefield and not just visually !! what about calls some copy calls of just about anything and everything ( great tit lyre bird etc ) regional differences even. so when you get long distance migratory species not often seen here they receive more attention to detail than the cursory glance given to dunnock lets say. how many have given a dunnock a good grilling and be amazed at the beautiful detail and delicate fringing ? stunning. its the same in nature supposedly no 2 tigers have the same pattern and the same with zebra so we could be seeing nature at work, diversification to establish which variance has the best chance of survival.
