Lagarto overo/Black-and-white Tegu11-2-17 © Elsa y Guillermo
Tegus can lose their tail spontaneously as a defense mechanism to save their lives. Thsi capacity is known as autotomy. Lizards have areas between the vertebrae with weaknesses and speciiic muscular adaptations which let the tail come off without losing fluids. The tail regrows, but not as it was. The new tail is a cartilaginous appendix without scales and vertebrae. It may ocurr that a fork-like tail develops as is the case of our tegu.

The Screaming Cowbird parasitizes almost exclusive the Greyish Baywing. In the photo a young Screaming Cowbird is claiming for food. The plumage of both birds is quite similar. But on the screaming Cowbird black spots are already appearing.

In most records the storks are flying past the reserve. The few ones where it can be seen inside they are very far. The time has come to watch it from very close.
07-02-17 © J. Simón Tagtachian
The stork forages either in water or in land. It eats fish, frogs, small mammals, snakes and invertebrates.

This man was sleeping on the tree branch which is some 50 meters from the beginning of Viamonte to the new viewpoint. He was at a height of 1,50. Just when I take the photo one of the security personnel rides by bicycle, wakes the man up and tells him this is a reserve and that he can not climb up trees... you should have seen the bark marks on his face!!!RAP

Carduelis carduelis
Cardelino/European GoldfinchCardelino/European GoldfinchRAP © 2-2-17
The European Goldinch belongs to the family Fringillidae like our Hooded Siskins and it is a bit larger than they are. Together with the European Greenfinch
Carduelis chloris are European species introduced in Argentina. The Goldfinch seems not to have exceeded the limits of the Province of Buenos Aires. Its distribution area is a strip bordering the coast of the province till Necochea.
