A very diverse group and many sharing the same activity: preening. With their necks stretched to get to the unreachable feathers to keep them clean and free from bugs. Besides the red shovelers, there are yellow-billed pintails, black-necked swans, a white-winged coot,a brown-hooded gull, a pied-billed grebe and others that cannot be identified

Simón found the cygnets in his photos of August 28th. Only one cygnet's head is seen clearly arising from in between the plumage of the adult's back. Another head seems to appear on the other adult's back. Since cygnets hatch all at the same time the six cygnets are certainly hidden in the plumage.
