The birds and the windows
I was sitting with my wife on the benches behind the Conference House when I heard a sharp blow and an insistent and "different" cheep.
What had happened? A juvenile Golden-billed Saltator had collided against the glass windows of the Conference Room. It was lying on the floor and did not fly.
Las aves y los vidrios/Birds and Windows
It did not seem to be fine. It was stunned by both the impact and the shock.
Las aves y los vidrios/Birds and Windows I picked it up and looked for an employee to find a solution for the bird. Luckily I met Santiago Sarmiento, who willingly offered to take the bird to the Rehabilitation Center at Viamonte. Since I knew what had happened, I told him that I had worked for a while for a Swiss Company at General Rodriguez. They cared for everything related to nature to the extreme. The canteen had big glass windows which birds often struck causing injuries and even death to them. So they decided to put stickers (photos-drawings) of the raptors common to the area. They were in real size and in a hunting attitude. And it was successful since birds did not get near the canteen.
Perhaps something similar might be done on the glass windows at RECS and see what happens with this low cost solution. I do not know whether this type of accidents is frequent, but one is enough. It is not nice to see a bird like the one on the top photo, isn't it? Photos and text © Nicolás Giorgio

In "The birds in front of their image" this subject was already introduced but we lacked registers of the sort in Costanera. Here it came through Nicolás, who also helped with stories for that article. The strike was strong enough to stun the Golden-billed Saltator and Nicolás's ear was acute enough to perceive an abnormal situation. As a result Simón, in charge of the COARECS, sent this information to the Operational Manager, Germán Ausina. Germán forwarded Nicolas's proposal to the biologists in charge. We hope to have good news soon.

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 "...
