Chiffchaff Migrant? 27/03/2010

Present KH AM JS MW RG.
The idea was for some ringing but ride preparation for the summer was priority.
Almost immediately we caught a Chiffchaff which had been previously caught on  19/09/2009.  This split the team into two camps.  Two people thought it had possibly over-wintered and the other three that it was a returning migrant.  The pros and cons to the discussion I leave you to work out.  The re-trap Blackcaps were initially caught on the same date as the Chiffchaff but obviously had over-wintered.
The totals for the species ringed (re-traps) were as follows: Blackbird 2; Goldcrest 2(1); Chiffchaff (1); Dunnock 3(1); Robin 3(3); Blue Tit 1; Great Tit 1; Blackcap 1(2).
