The records of this egret are mainly on the wing crossing the reserve. A proper habitat for this bird is not present here. Anyway they landed in the pond. Heads popped on and off as they bent in search for food. We counted 6 individuals

Belongs to the family Crambidae, subfamily Pyraustinae. The adults are nocturnal. This species is considered a pest of the Cucurbits since the larvae feed on shoots and flowers weakening the plant. They also burrow into the fruit exposing it to illnesses.

La más fácil de fotografiar de las lagunas por los balcones que permiten una visión completa. Las fotos fueron tomadas a lo largo del borde del Camino de los Lagartos desde Brasil hacia Camino del Medio. Los parches de agua están cercanos a la orilla, pero el agua no llegaba al borde del camino.
Laguna Patos/Duck Pond12-5-18 © Cora Rimoldi
It seems water covers the pond but emerging vegetation still stands. The biggest water mirror is very far.
Gull Pond Laguna Gaviotas/Gull Pond12-5-18 © Cora Rimoldi
This pond presents a more advanced state than the Duck Pond's similar to the previous recovery. The water mirror is far more extended though patches of vegetation can be seen

Seen from the Middle Path and also dry shows now an important water mirror.

After a marked drought which dried the ponds, the rainfall finally arrived in earnest. Since a month ago the bad weather has practically hindered the access to the reserve during the weekends. We can only walk along the sidewalk and capture birds at Coypu Pond either visually or aurally.
Diego Bastías told us that there was a water mirror in the inner pond with black-necked swans. In Alec's photo an extended area of water can be seen at the Gull Pond, whereas at the Duck Pond there seems to be only a "puddle" of water. Quite promising but there is still a lot to fill.
