If there are silk floss tree fruits Chorisia speciosa, these parakeets are likely to come down to eat

The Hepatic Tanager also found a place in the classification. The mithocondrial DNA analysis were conclusive in that the Hepatic Tanager belongs in the Cardinalidae, though it seems strange to see it together with the grosbeaks with such prominent bills

Ignacio discovered this caterpillar on a trunk of Sapium haematospermum when we got near it looking for a bird. The caterpillar passes unnoticed but the contrasting white coulour of the eggs, which practically "adorned" the whole of it, called our attention. These are ichneumonid wasps eggs

Ignacio discovered this caterpillar on a trunk of
Sapium haematospermum when we got near it looking for a bird. It is well camouflaged and passes unnoticed. The contrasting white coulour of the eggs, which practically "adorned" the whole of it, called our attention. These are ichneumonid wasps eggs.

I thank Gustavo, the author of the photo, for sharing this finding. It was taken during a visit of the Coa La Plata (Observers' Club) to Costanera Sur in july 2012. 
This is not the natural habitat of the Black-backed Grosbeak. Its distribution range covers a vertical stripe from the yungas up north to the Province of San Luis
