Species of the Month - November 2013

Whooper Swan

Cygnus cygnus

Whooper Swans are winter visitors from Iceland.  They are liable to be found on any of our lochs and can also sometimes be seen offshore, or in flight from one water-body to another, making their deep whooping call as they go.  Occasionally they are seen in marshy ground beside a loch, grazing on the vegetation.

Cygnus cygnus

Each year a few Whooper Swans manage to breed in the far north and west of Scotland, but any seen in our area during the summer months are more likely to be individuals unable to migrate due to injury.  If you see a pair in summer, of course, there is much more cause for excitement.

Cygnus cygnus   Cygnus cygnus, juvenile

The right-hand picture above shows a juvenile.  These are grey when they fly south with their parents.  They become paler during their first winter but do not attain adult bill colour until after they return in the spring.


Cygnus olor & C cygnus

Whooper Swan being driven off by Mute Swans.  The difference in bill shape and colour is obvious.  It is much harder to tell Whooper Swans from Bewick's Swans, but the latter are extremely rare in our area, with none being sighted in most years.  Bewick's Swans normally have the yellow reaching less than halfway along the bill.
