Err, geese.

They look like Aylesbury ducks to me

Fair enough, I'm no duck-ologist. Always glad to learn!

I love the way they abide by his flagging directions:)
Sorry to be a little pedantic Spacemagic, I could be wrong about the variety of duck though they are very commonly kept by proper duck-ologists

No probs - I like pedantry
Are they obeying the flags, or are they following the guy off-screen with the big sack of duck food?

Either is possible:)
It is well made if they staged it. The ducks even stop when he lifts the flags.
