This should be freely available at http://www.tandfonline.com/doi/abs/10.1080/03078698.1995.9674091 but contact me via http://www.merseysiderg.org.uk/ if you need help to see it.<br />My male winglengths ranged from 142 to 159mm and females from 138 to 156mm, means of 151.9 (adult male), 150.0 (first-year male), 147.5 (adult female) and 146.1 (first-year female), much larger than any other published data.<br />I wrote 'the large size of these birds suggests that many of the Fieldfares in the study area came from the northern part of the breeding range, with the species following Bergmann's rule.' I had two recoveries at latitudes of 64N and 65N, amongst the most northerly of all British records http://blx1.bto.org/ring/countyrec/resultsall/rec11980all.htm which lend support to that suggestion.Anonymoushttps://www.blogger.com/profile/14258919527205864140noreply@blogger.com
