Interesting to see how it stands on water as if being supported by the tail and with the feet underwater, catches an Oligosarcus jenynsii and takes off. After all the effort it loses the prey.

Carlos Ferrari, Silvia Vitale, Simón Tagtachian and Diego Monteleone among others managed to identify three individuals using a telescope. As Silvia says what pretends to be a photo of the skua was taken at a distance of 700 mts.
Carlos says: "There is no doubt of what we saw. In the photo we can see a posture typical of a skua in flight and also a buff glimpse which could be seen at times depending on the angle. The skua is bigger in size and more robust than the Grey-hooded Gull. The white spots on the primaries could also be appreciated.

Sergio discovered the juvenile rufescent tiger-heron when it was vigorously beating the white-tufted grebe against the vegetation. The grebe flapped, so it was alive. Unluckily we do not know how the situation ended. Certainly bad for the grebe. The rufescent tiger-heron left carrying the grebe.

Nicolás told us "They fought fiercely. It is remarkable to see how they use their bills and legs (nails) to attack, mainly the eyes. It seems the fight was not over food but territory. They attacked each other, stayed lifeless and then again resumed. Always in the same place. Finally they left. They did not look hurt, but I think they were exhausted.<br />It is to be noted the attitude of a rufous hornero which observed the fight but it did not take sides. Well, it is our national bird "...
