After spending many sessions feeding the ducks the stale remnants of my loaves with my son, I saw an expression on a ducks face that made me reconsider what I was doing. 
It was 9:30 am as we scattered our contribution to the ducks and pigeons on our way to the park. The pigeons were eager to eat up our gift. But as our crumbs hit the water the ducks seemed to look over and ever so slowly and reluctantly made their way over with a look that said to me,"oh for fucks sake, bread again". They swam over and ate the bread half arsed. An hour later on our return journey home there was another man emptying a whole bag of bread into the ducks area. It seems these animals have shit loads of bread given every hour of the day by humans with eager faces watching them eat with excitement all believing that the ducks will be chugged at the offering. 
I don't know what else ducks eat but surely there must be something else as bread is not naturally going to fall into their paths. What is their natural food supply? 
Anyway once the duck pond was full of bread by this new man throwing loads in, the ducks set about the business of eating it, but I got a sense that all they were doing was cleaning up. 
The ducks radiated their thoughts through their expressions. 
"oh thanks for nothing, we had a clean pond and now someone else has thrown their junk in it. I guess we have to clear that shit up now then". 
Why is it that pigeons get thrown chips but not ducks. The next time I have a pizza, I am throwing some to those ducks, in a tidy pile though.  If I ever am that hard up that I'm going hungry I too will loiter at the duck pond in the hope to share this crappy bounty.
