Drake Goldeneye - Duckpond. Lovely close views of this stunning duck. I watched it with a sense of melancholy though, as with numbers down to just three or four birds at this end of the river, it's possible it will become a real rarity within the next decade.
I think this is Sweet Violet (blunt sepals and small hairs on leaves) but I'm not sure. Does anyone know if I can rule out a related garden escape?
