A Pigeon takes to the Water

This evening I was watching some Canada geese on the Kennet in central Reading when something rather strange happened: a feral pigeon flew down and landed on the water amongst the geese.  I must have forgotten itself because the splash it caused seemed to surprise it and it immediately flew up again.  I suppose that it could have been picking up a piece of bread off the water but I didn't see any bread, and nobody was feeding the geese at the time.  I prefer to think that this bird just made a mistake and recovered just in time
