I know this is not a Calderdale report but I find this information amazing about migrating Blue Tits over the last 2 days at Nabben, Falsterbo, Sweden.
21,660 on 30th September and 87,400 on 1st October
I can't say I ever thought Blue Tits were 'big movers' but this proves otherwise !!
If you start seeing a lot of Blue Tits on your garden feeders in the next few weeks, who knows where they might have come from?
