Birds -- Regent's Park, London, waterfowl collection
Regent's Park has an impressive collection of waterfowl from around the world. With species that naturally occur in the UK, it isn't always obvious whether examples in the park are part of the collection or wild visitors. I've assumed that Tufted Duck, Common Pochard, and Greylag Goose are wild, and fowl of all other species photographed are part of the collection.
