In reply to Michael Hood:
Twice now I’ve seen a male with prey just standing immediately after the catch. I’m guessing they like to wait until the prey stops moving before they fly off to eat, or so it seems. I’m sure they must see me so something is making them stay for a minute or two - time to go and get the camera and get a shot.
I feel sorry for my house sparrows as they are very twitchy these days. Gave me an opportunity at the weekend to try to work out what call/alert they use for rapid dispersion without success. It seems that something triggers all of them to head for cover with perceived danger. If I’m in the garden they take their time to move when I do, but it is instantaneous when something alerts them.
