Walk on Sunday 26th We were invited by the Operational Manager, María Inés López Lo Celso, to share a walk with a group of birdwatchers. Among them it was Tim Appleton, cofounder of the most important Bird Fair of the world, the British Bird Fair, Peter Dunn, from Naturetrek, Deborah Perrine Sturdivant from Holbrooktravel y Brian Small, photographer and illustrator of bird books. The walk began at 11;30 and lasted two hours. From Viamonte to the coast and back to the cottage. Thouth it was very hot several birds were seen. As we said goodbye I asked Brian to draw something for us. Literally in the air and on a small card he drew a beautiful passerine. grupo

As we were walking back along the Lizard Path a Grey-necked Wood-rail familiy crossed the path. But a chick stayed behind on the other side. As too many people were walking by, the chick did not dare to cross. Some seconds later an adult crossed to the other side. We waited to film something but they did not appear.

As usual some photos to illustrate what was seen. I thank all the photographers who sent material to be shared.

Urutu Pit Viper
Rhinocerophis alternatus
Yarará grande/Urutu Pit Viper I was trying to photograph a saffron finch where the Canal Viamonte reaches the river. As I got near I perceived other birds in the same tree. There was a checkered woodpecker and some thrushes and sparrows were flying around. making a lot of noise and moving near the ground. The scene called my eye. When I saw the viper I realized why birds were so agitated.
