This was perhaps because of the complete (bar one or two?)lack of pre winter 2012-13-ringed birds i.e. those imprinted on the site for more than one winter period. This was unexpected and, allied to the probably abundance of natural food on the saltmarshes in the mild conditions, presumably contributed to Heysham not being used as a northerly outpost of reliable food for the Twite flocks frequenting the saltmarshes to the south. In this respect, there are no flocks to the north of Heysham, and therefore Heysham is the most northerly utilised food source with no 'through put' of individuals to and from the north. There are good numbers on the saltmarshes to the south of the Lune and, as some Twite are still visiting Heysham, more can be expected as natural food runs out and 'the word gets round' at the night time roost(s). Indeed there are signs that this is happpening (e.g. 29/12) Pete Marshhttps://www.blogger.com/profile/09461363671751316069noreply@blogger.com
