Celtis iguanae
Tala gateador/Iguana hackberry© Sergio Cusano
Family Celtidaceae. Plant with orange fruits which is in the Middle Path. Once by a bench (now removed) with view over the Grebe Pond.
Cattail
Typha sp.
Totora/Cattail© J. Simón Tagtachian
Family Typhaceae. It is found worldwide. It inhabits marshes and the edges of water bodies. They multiply through seeds which are dispersed by the wind or through rhyzomes forming dense stands, cattail beds.
In the photo the inflorescence, the brown terminal spike is seen. Here three different species can be found: Typha latifolia, Typha domingensis and Typha subulata. They cannot be distinguished with the naked eye, so they appear as Typha sp.
When the ponds went dry in 2008, the cattails covered the whole beds of the ponds turning them into cattail beds. With the filling of the ponds with river water, the cattail beds are being removed.

Family Apocynaceae. Exotic tree native to tropical America
Like the oleander
Nerium oleander it is a toxic plant either by ingesting the seeds or getting in contact with its sap. This plant is by a viewpoint, the first one on the right along the Lizard Path in direction to Viamonte. It is very showy for the yellow colouring of flowers contrasting with the green of leaves.
Ash tree

Higuera/Fig tree © Claudia Mon The fig tree is an exotic plant native to the southeastern Asia and the Mediterranean. It belongs in the Family Moraceae. Its fruit has been appreciated as a highly nutritous food since historical times. It has been introduced all over the world.
The fig is very distinctive. It is know as infrutescence or false fruit since it is in the inside where the fruits are.

Robber fly
14-02-16 © Sergio Cusano
Very different from common houseflies. This fly is very aggressive as it name indicates. The mouthparts form a proboscis which is stabbed in the prey. It injects toxic substances and enzymes to both paralyze the victim and digest its contents, which then are sucked. It feeds on insects. In these two cases the preys may be a sweat bee of the family Halictidae.

The greenish legs and the bill led us to erronously conclude that this was a juvenile Little Blue Heron. Lui explains to us that the little blue heron has the face of another colour and that in this plumage outer primaries should be expected to have some black colouring.

New mammal species: Agile gracile Opossum
Cryptonanus chacoensis
Comadrejita ágil/Agile gracile Opossum20 3 16 © Favio Gustavo Belotto
Favio found this little opossum at the edge of the trail on the Alisos Path. He says it was quiet and then got into the grassland. The size in this position would be 5 cm (without the tail).
This opossum is in fact very small and its prehensile tail is longer than its head and body together. It is arboreal and nocturnal. Females lack a pouch.
Up until recently it was known as Gracilinanus agilis chacoensis and now its name has changed to Cryptonanus chacoensis.

Walikng along the coast from the Brasil end we found two individuals. The first one rapidly crept into the vegetation whereas the second one set to cross the road in a very slow manner. We had a feeling that something bad would happen to it so we stayed and warned going by cyclists and runners about the snake. It took it more than five minutes to reach the other side. Once safe we continued.

I saw the Barn Swallows over the court area at Viamonte. First there were 5 or 6. I stayed there ready to shoot them on the wing. Then there were two individuals, the ones photgraphed. All of them moved very high and quickly from south to north. Besides there was a bigger number of Brown-chested Martins, groups of 20/30 which flew in moving circles. Along this same "corridor" caracaras and chimangoes went by.

The fight between the savanna hawk and the caracaras

I heard raptor voices, look up and see two caracaras attacking a hawk very aggresively. .. A second look, reminded me of known silhouette, since I had already photographed it many times in Ceibas and in Perdices. It was a Savanna Hawk.... One photo is good but the rest show the fight

Never mind whether this is a Australoheros facetus or a Gymnogeophagus meridionalis, it must get rid of its pirate relatives first.

There are too many rosy-billed pochards in the pond. This individual is changing into the adult male plumage. His eyes are already red and it is painting black. He is certainly one of the too many ducklings we saw born in the reserve.
