You would think that fewer birds would be forced out of the mountains in these circumstances so perhaps there is another reason. Perhaps its been too warm and the 'mountain' species (specifically) are searching for colder climates?Just two minors points for the above - the ringed Snowfinch was a Spanish recovery ie it was ringed in Germany and later recovered in the Spanish Pyrenees. Secondly, there have been 36 records of Accentor in GB (with one currently somewhere on the south coast) and a handful of Wallcreeper so perhaps more out of range records than Germany - might point to them being Pyrenees (or nearer maybe Massif Central) rather than alps....</blockquote>
