A pair of rufous hornero foing in and out fo the nest apparently abandoned. They seemed to be remodelling it. Very early, isn't it?

New amphibian species

Lesser swimming frog

Pseudis minuta

18-04-14 © J. Simón Tagtachian

Andrés Sehinkman, who identified this frog, tells us it is typically found in flooded areas and lakes. It is common in Buenos Aires, Entre Ríos. Santa Fé, etc. It has very developed interdigital membranes on their hind limbs, typical of aquatic species.

Ithra crescent

Ortilia ithra

22-04-14 © Nicolás Giorgio

Variety rufocincta

Variety rufocincta. Found in Sierras de Córdoba. It differs from the crescent we see here in that it has a rufous submarginal line on the rear wings.

Records of 2013

All these birds were registered somehow between March 2013 and March 2014. And we hope all these and too many others will be present on the following list. Have a look at it to be better prepared.

19-04-14 © Claudia y Tito Di Mauro

Otra familia nueva de barcinos. En los patitos las alas son desproporcionadamente pequeñas frente al pico y a las patas. Estas partes están más desarrolladas porque son necesarias para procurarse el alimento.

White-tailed Hawk

Geranoaetus albicaudatus

18-04-14 © J. Simón Tagtachian

Light morph. Simón and Ignacio saw this hawk which first quarrelled with caracaras and then with two Harris's hawks. Two silhouettes to bear in mind. Harris's hawk's wings are rounded and broad. White-tailed hawk's are wide at the base and pointed. Harris's hawk's tail is longer than that of the white-tailed.

About 15 minutes later they swa another individual which was not the same judging by the feathers of the wing.

New butterfly species

Mexican silverspot

Dione moneta

12-04-14 © Sergio Cusano

This species inhabits from the south of the United States to the north of Argentina. To have found it here far from its distribution range has been quite a surprise. And there was not only one, but four individuals. At first sight both the dorsal and ventral side of the wings look much more like the Gulf Fritillary Agraulis vanillae maculosa, a very common species here. But at a closer look we noticed that the orange colour was stronger, this individual was bigger and that it lacked the black dots. The genus
Dione contains three species, D. moneta and D. glycera which are in the north of the country and D.
juno, Juno silverspot, which frequents Buenos Aires and is found in the reserve.

Wattled Jacana

Jacana jacana

Photos on top show the three jacana chicks from the nest detected by Amelia. They are more than three weeks old. The chick of the photo below belongs to the clutch which hatched at the beginning of February. They are more or less a month and a half older than the previous ones.
