Geese on the Hiz

I've had a mad week and computer issues (which I am hoping are now sorted). Have been blipping but just not posting them so back blipping after this. This was taken this morning. I have no idea why all the birds were on the bank, I couldn't see any food on the ground but thought it made a good shot, particularly when I spotted the pigeons in mid air on the left.

Will back comment too as soon as I have time.
