On Saturday 16th we reached the coast and from the viewpoint we managed to see thre or four lines of floating vegetation in the distance. We were surprised at the size of these mats. We knew they would appear any time due to the floods.
These floating masses may act as a dispersal of fauna y and they are doubtless one of the reasons why the reserve is so rich and diverse. On them reptiles, amphibinas, insects and birds as well are transported. They are home for too many species but unluckily the press only refers to them as ways of dispersal of venemous snakes. At the reserve there are many species of snakes, most of them inoffensive, but there has always been he Urutu pit viper for more than 20 years now. Al the reptiles are more active during hot months, that is way it is advisable to be more cautious and follow the rule of not descending from the paths. In case of detecting any species of snake, inform the Personnel.
On Sunday Silvia came back to the place and the floating masses on the shore.

At last we managed to record this butterfly. A very difficult butterfly to photograph for the way it moves. It flies erratically and quickly. It was seen along the Canal Vaimonte where the thick rope closes the access to the path. This window in the vegetation let us see them flying by. They crossed the window in one way or the other and sometimes got out of the vegetation onto the road. Simón saw three individuals. I recorded only two. This took us more than half an hour.

Unluckily we found this opossum dead at the edge of the Lizard Path. We knew there were white-eared opossum but had no register of it. This individual had no bites. It only had a small wound which must have been the cause of death. Run over?
With Carlos's digital method we estimated the opossum's body to be less than 30 cm long. This opossum is crepuscular. It is terrrestrial, but it can climb with agility using the tail.

Each parent is feeding a chick at a time. Parents must teach kids the tecnique to remove the fleshy part of the apple snail. So they need kids to focus. If other siblings were present there would certainly be fights over food or distractions of any kind.

2006 - 2016. We turned 10! A big thanks to all those who help build this site no matter how tiny the contribution is. This site is full of good vibes of all the people who share, contribute and have fun with birds. We are a lot and the number keeps increasing.
My acknowledgment to Horacio Reinaudo, the founder of this web site and my gratitude to the "teachers" for their teachings which encourage us to go ahead, to those who share their material or provide information and to those who follow the site.
Let us tackle the following ten years, this team is ready for the challenge.
A small sample of the observers that participate in the walks. No chronological order has been kept and there are lots of collaborators and observers missing.

Some minutes before we had been told that a photographer took photos of this viper eating a Brazilian Guinea Pig. We found it near the road and immediately informed the Personnel. It was motionless. Perhaps digesting the guinea pig. This viper is not aggressive except if it fels threatened. Watch where you walk and do not leave the main trails.
