Pochards

Yesterday morning I walked with round the Reading University lakes with Zoe.  On the large lake there were still a few shoveller ducks under the bushes on the north side.  We also saw three brown headed grey ducks which I hadn't seen before.  Their backs were light grey and their side an even lighter grey.  On getting back home I was able to tentatively identify them as common pochards (Aythya ferina).

We saw one of them yesterday, in with a group of shoveller ducks.
