That was beautiful to watch GW. Thankyou. I'm sure I read recently that the birds fly in groups of seven, and just follow on.
Glad you liked it, I'd love to work out how many are in the group at it's biggest it seems to be thousands just before they finish their display and roost down.
We were returning home tonight when we saw a huge flock of birds doing exactly the same. I thought oh loverly its the Starlings. It wasn't. It was hundreds of Rooks and Jackdaws making for their roost. It was a wonderful sight as well.
Really, so other birds do it too?
