The man feeding the ducks said he regularly fed them at that spot and that the drake gadwall would always be following a female mallard. He’s not a birder but who knows…? Perhaps imprinted at birth or a bit of a personality?
We have had four or five blackbirds interested in the berries on our Rowan tree, Westbourne road. There seems to be one in charge, controlling the store, perhaps seeing that it lasts the winter 🙂
