London and the southeast of England boast a rich array of waterfowl, with several species commonly observed in parks, waterways, and coastal regions. Mallards, with their iridescent green heads and chestnut chests, are among the most familiar ducks, while their smaller relatives, such as teals and gadwalls, can also be spotted. Coots, with their black plumage and white bills, are frequently observed diving for food in ponds and canals. Shelducks, with their distinctive orange beaks and black and white markings, are frequently spotted along the coast and in estuaries. Geese, including Canada geese and greylag geese, are also common visitors to parks and fields, frequently observed grazing or resting in large groups. Mute swans, with their elegant white plumage and black bills, adorn the waterways of London and the southeast, while their smaller relatives, Bewick's swans, can be seen in some coastal regions.
