Mute Swan – Best viewed large
Although this bird can be tame, especially to those who feed it daily, it is aggressive in defence of its nest, and its size and impressive hissing make it a formidable adversary for animals as large as a fox. Large waterfowl, such as Canada Geese may be driven off, and there have been many reports of Mute Swans attacking people who enter their territory. The cob is also responsible for defending the cygnets while on the water, and will sometimes attack small watercraft, such as canoes, that it feels are a threat to its young. The cob will also try and chase the predator out of his family territory, and will keep animals such as foxes and birds at bay.
The familiar pose with neck curved back and wings half raised, known as busking, is a threat display, mainly shown by males but also females to a small extent.
