Gathering of moulting mute swans

We meet such gatherings of swans in sea bays already for  weeks. The moulting lasts for a long time, swan feathers can be seen on the shore and on a calm water surface still in August..

Swan flocks feeding in such shallow waters are mostly non-breeding young birds but also adults whose breeding has been unsuccessful for various reasons.

Adults with chicks (cygnets) keep to themselves and the male drives off all who approach; sometimes such encounters may become quite harsh.

The hatching of the cygnets started at the end of May, thus the offspring that we meet is about a month old.
