Here four individuals. But Javier saw at least 9 individuals. After the breeding season the male masked duck changes its plumage into a female-like one, to the extent that it is difficult to tell them apart. Here we can see some already changing into the adult male plumage.

A pair of black-headed ducks, the only parasitic duck, shares the scene with a cocoi heron and a white-tufted grebe. The interesting thing is that on the isle behind several ducks can barely be seen in the thick vegetation. This isle will certainly be a good place to breed since ducks are very well protected. Is this pair already monitoring the area?

This footless chimango caracara stole this piece of bread from the starlings, which had taken it from a garbage bag. As it was carrying it the piece fell onto the ground. The chimango came back to recover it and here we can see it leaping on it.

We were about to leave the reserve when there was quite a stir in the tipu trees near the water tank. Eduardo immediately associated it to the ferruginus pygmy owl and we started to look for it. The fuss was incessant in several a couple of trees. Birds even stopped in the tree across. All of them were very excited. It took us a while to find it but Eduardo finally spotted it. Other birds like the white-crested tyrannulet, the Straneck´s tyrannulet, the masked gnatcatcher and the tropical parula were present.
