Garganeys are unusual among our ducks in that they are essentially summer visitors, migrating here to breed. Most of our ducks are much commoner in the winter time, but not the Garganey. They start to return to their breeding sites in March, but they are scarce, with fewer than 100 pairs in the country. Most are concentrated in the east, particularly East Anglia, and south-east England, but with localised populations elsewhere, including western Wales and the Scottish Borders. They are tiny ducks (about Teal-sized) and males are distinctive and very attractive, with a striking pair of long white supercilia. They are shy and retiring, disappearing with ease into flooded vegetation, in their shallow wetland habitat.
