This coscoroba family with chicks already grown appeared in this pond. It must be one of the families which bred in the other ponds and moved. We can also see a solitary black-necked swan, A contrasting view with the too many in Duck and Gull Ponds

Fight/Chase

Fight between two males. They begin in a ritualized way but then it turns physical. The reason: a cygnet 

Nest/Active nest

The incubation began about July 14th and by August 28th we witnessed the moment when they left the nest. In this case it was about 40 days.

This nest was build in the Coypu Pond in 2007. On 30th of June this coscoraba swan was moving the material. At the end of our walk that same day they had already raised this pile.
