It is easy to understand how the Mute Swan came to be so called. Gliding gracefully along with head held high, it looks too gently to be a noisy bird. Let’s discover detail about Is the mute swan really mute.
Is the mute swan really mute
It is not altogether a silent bird, however. A party of swans moving up a stream will often make small grunting noises to each other, for example. Other ‘conversational’ sounds made by Mute Swans include growls and short yaps, and all these sounds probably serve to keep the group together.
A more sinister sound is made when the mute swan is angry. It arches its neck and half raises its wings before lunging at an intruder with fierce hissing sounds. (It is well known among anglers that you can usually deter a swan from coming too lose by hissing loudly at it.)
Which are the black swans?
Not all swans have pure white plumage. Two species, one from Australia and New Zealand and one from South America, Have black plumage. The Black Swan must have been an amazing sight to the seventeenth century explorers of Australia who had previously seen only white birds.
Black Swans soon arrived in England and America and were popular as decorative curiosities on the lakes and ponds of stately homes. The other black swan, with less black in its plumage, is the Black-necked Swan from South America.
It has a black head and neck, a white eye stripe and a red bill. It occurs from southern Brazil to Patagonia and also breeds in the Falkland Islands.
