Comment In Denmark (bewickii): For identification in trickier situations it will be useful to learn the proportions of this species compared to Whooper Swan - the head is very long/large, almost half the length of the neck, whereas it only is a third of the length of the neck on a Whooper.

Both of the 'yellow' swans have short tail meaning that you will never see a tail sticking out like it does on a Mute Swan. This is actually a very reliable feature both when seen swimming and sleeping.
