bipeds called ducks

I recently noticed some different bipeds. They seem to glide on the water and often go around in groups especially if a human biped is throwing white stuff into the water.

They are really cool as the can walk too - but they seem very slow. I went up to talk to them yesterday but the slid into the water with a quacking sound. Like other similar bipeds I have seen they can soar into the air as well.................I have continued to practise my high jumping as maybe that will help me fly too!?
