Mallard ducks (Anas platyrhynchos) at Martin Mere, A Wildfowl and Wetlands Trust bird reserve near Southport, Lancashire, UK. Long term ornithological surveys have revealed that fewer wildfowl are coming to the British Isles each winter, as climate change leads to milder winters, meaning some birds are staying on the continent, closer to their breeding grounds.
