Another session at Middleton this morning and it was very good, if a little puzzling. It was as clear as a bell first thing yet, for example, there were five un-ringed Blackcap in a mist net well before dawn. We have caught nearly 50 Blackcap at Middleton this week without a single re-trap. Indeed, despite ringing for the last four mornings, the number of re-traps has been really low with, for example, just a Wren (and local nestbox Great Tit bearing a B ring) out of 60 odd birds this morning!
Sorry about the lack of proper migration postings the last two days - home computer playing up.
