Parental care

The first family was sailing from Brasil to Viamonte. After I had seen the bittern I found the second family ten blocks away. At first I thought it was the first family which had reached there, but right away I remembered that the number of cygnets was smaller.

Behaviour

The orphan ducklings want to join the ringed teal family, but the parents quickly lead their chicks far from the ducklings. Nevertheless, the rosybill ducklings insist in following them. Judging by the way the rosybills rush off, they seem to have been shooed away by the adult ringed teals. They end up by floating by themselves. 

Behaviour

Six rosy bill ducklings were alone and tried to join a ringed teal family but were rejected by the adults

Parasitism

The same rosy-billed pochard family parasitized by fulvous whistling-duck on two different occasions December 20th and January 21st.
