I think the house martins (Delichon urbicum) left us today, heading south on their migration to Africa. The RSPB tells me that they leave the UK in September and October, but I wonder whether we saw them leave today. Normally their flight is in loose, open groups, hunting high over the village in a wide open looping flight. At about 10 this morning Chap and I saw something very different, a tight, low flying group of maybe forty individuals flying directly to the south / south-west of us, and not returning. A couple of stragglers followed a few minutes later. I haven’t noticed any over the village since.

It wouldn’t surprise me if they have left a bit earlier than usual, as we have had a very cold and wet few weeks, more November-like that August-like.

It reminds me of the time some years ago when I watched a group of at least a hundred house martins all settle on the sloping terracotta tiles of the roof of a nearby tall house. I was alerted to them by the terrific noise they made as a group, a lively twttering and calling that went on for a couple of hours. And then they all flew off. And that was that – they’d gone for the year. I’d never seen that behaviour before, nor have I since, and assume they were marshalling themselves before the grand depart.
