Pochard failing the bread test

well not actually bread because the kids at Waters' Edge are encouraged to buy bags of wheat to feed to the ducks; so whenever a potentially wild / rare duck turns up at a slightly dodgy location, ie one frequented by lots of people, we have the debate over whether it came to bread -- locally Pochard occur on most of the  pits and are pretty unapproachable but on Waters' Edge some of their number have realised that a few screaming children represent no threat and the free grain on offer means you can feed within 6 feet of human beings stood on a boardwalk above you -- there are also plenty of escaped Tufted Ducks doing the same thing -- so no hard and fast rules birds do what they want when they want
