How does a swan fly?
Swans are gracefully long-necked, heavy-bodied, big-footed birds that glide majestically when swimming and fly with slow wingbeats and with necks outstretched. They migrate in diagonal formation or V-formation at great heights, and no other waterfowl moves as fast on the water or in the air.
Why do swans put their legs on their backs?
It is normal for swans to swim with one leg tucked onto their back. The large surface area of the webbed foot makes it easier for heat to be transferred from the body to the air, cooling the swan. This heat exchange could also work the other way, with the feet absorbing heat from the air to warm the bird.
Why would a swan be alone?
If the nest is vulnerable to natural events such as high tides & floodwater then it should be left alone so that the swans can learn from the experience – if a young couple lose a nest under these circumstances then they will learn not to build a nest so low down the next year.
