However, the fringes of schinzii are very similar, and I'm not sure if they would be seperable in the field. People quote "cold-toned, small billed" as being typical for artica, however, the bill lengths of schinzii and artica overlap even at the shortest end of the range. Several have been claimed in Cambs recently, but there was no real substance to support this. No doubt they occur (rarely?) in eastern England, but proving it in the field may be impossible. Also, artica and schinzii may overlap on breeding grounds in Greenland.<BR/><BR/>Cheers,<BR/>Mark HawkesCBChttps://www.blogger.com/profile/14747508861615396892noreply@blogger.comtag:blogger.com,1999:blog-7197007.post-39533520449649321112008-08-15T21:30:00.000+00:002008-08-15T21:30:00.000+00:00Btw what is your email- I was looking for some sho...Btw what is your email- I was looking for some shots of vagrants which have birders in them or vagrants in unusual surroundings e.g. snowy owl on a nudist beach or lancy on your foot, something like that.

Would be interested to see if you have more success in nailing this one- it has got a lot going for it.Peter Alfreyhttps://www.blogger.com/profile/06561747770128374819noreply@blogger.com
