The genus of this passerine has changed once more. I knew it as Carduelis. In 2011 it became Sporagra, when it was separated from North American and the Caribbean fringillids, which comprised Spinus. New DNA studies place them now along with the Spinus
Here we found a small flock of 15.

Laurentia Emperor
Doxocopa laurentia laurentia
Zafiro común/Laurentia Emperor© J. Simón Tagtachian
Laurentia Emperor female is very similar to Syma Sister
Adelpha syma, the Adelpha seen at the reserve. Differences: The white stripe is narrower then the orange spot in Syma sister
Adelpha syma. Syma sister
Adelpha syma Has more lines between the white band and the edge. Syma sister
Adelpha syma ends in a small orange dot which Laurentia emperor
Doxocopa laurentia laurentia lacks. This laurentia is very torn and this detail cannot be appreciated. These are dorsal characteristics. If we compared the ventral side, there would be no doubt which is which since they are completely different.

Carrion-eating flies Moscardas/Blow Flies9 4 16 © Sergio Cusano
A big number of green and blue bottle bowflies (both belong into the Family Calliphoridae) were sitting on the vegetation. Near this swarm of flies there was a rat lying dead also covered with flies.
Though the scene is repulsive to us, this rat is the rich source of nutrients which will be exploited by both the larvae and the adults. Since they have no masticatory apparatus they throw up enzymes which dissolve the material to be consumed.

Sábalo/Streaked Prochilid© J. Simón Tagtachian
The fish around which the whole Plata ecosystem moves

The streaked prochilid is an iliophagus fish. It feeds on small organic particules found in the sediments. The Plata Basin is very rich in this sense basically because of the great amount of nutrients carried by the Bermejo and Pilcomayo Rivers coming from the Andes -that is why our river is brown- along with the size of these rivers and the places they go through. This amount of nutrients washed into the system and the peculiar characteristic of the streaked prochilid (it is iliophagus just like a few fishes among which is
Plecostomus plecostomus) support a big quantity of these fishes. That is why the streaked prochilid conforms, according to the investigations, a 50 or 60% of the biomass of the river. The streaked prochilid transfers a tremendous energy and all the rest of the fishes moves around this peculiarity. They are predated upon when they are eggs and larvae till they are adults. Though this basin is not as biodiversified as the Amazon one for instance. it supports more kilos per hectare and the secret is this fish. It is a plant but sort of. There is a joke which says the streaked prochilid has the capacity to transform mud into meat.
