Geese in flight.

I occasionally try and photograph birds and I think these are either Barnacle or Canada geese. The Canada geese round here are locals but the Barnacle geese fly here in the autumn to spend the winter, and then in the spring fly back to Scandinavia. (I am not a birder so I am a bit vague about the specifics). It's quite a spectacle watching them fly in a v-shaped formation, although here they just seemed to be socialising.
