News - November 2013

Cephissus siccifolius

November arrives and so does the rain-causing spittlebug. The females lay eggs preferably in legume trees and in Costanera the tipu tree Tipuana tipu is no doubt their favourite tree. Their waste is expelled in a foam-like way which covers and protects them. When these balls are too heavy they fall in the form of raindrops. But the tipu tree is not the only affected. Another legume tree which is parasitized by this insect is the Cockspur Tree

Paloma mensajera/Homing Pigeon Paloma mensajera/Homing Pigeon Paloma mensajera/Homing PigeonPhotos © J. Simón Tagtachian This is a ringed homing pigeon which was registered in the Federación Colombófila Argentina in 2013. Homing pigeons are characterized by their sense of orientation, fatigue resistence and flight speed. These skilful flying postmen have been the current mail system till the first communication technologies appeared on the scene. They carried messages attached to their legs. Nowadays pigeon keeping, which is the art and science of breeding domestic pigeons, is basically a sports activity. Paloma mensajera/Homing pigeon© J.

New species: Marbled Swamp-eel
Synbranchus marmoratus
Anguila criolla/Marbled Swamp ee-How easily we can be fooled. It has neither fins nor scales, looks like an eel, but it is a fish. It is commonly known as marbled swamp eel
Synbranchus marmoratus.
Anguila criolla/Marbled Swamp eelIt is a freshwater fish and is found in rivers, canals, lakes, etc. Here they were seen at the opening of the pipe. There were three individuals. Two were between 80 and 100 cm long and the other one, 60 cam long. Anguila criolla/Marbled Swamp eelIt was not taken out of water. The peculiarity of this fish is that it can breathe oxygen both in the water and in the air due to specialized adaptations in the gills. Ii is covered with a mucous membrane which facilitates moving on the ground and prevents the swamp eel from desiccation. Photos © J. Simón Tagtachian
New species: Black-collared Hawk
Busarellus nigricollis
Aguilucho pampa/Black-collared Hawk© Nicolás Pérez An old record, but very valuable indeed since this hawk belongs to the north and northeast of the country. There have already been some isolated records in the nearness of Buenos Aires in the last years. At Costanera it was seen flying around for 15 minutes near the Viamonte entrance.
Two turtles
Tortuga de laguna/Side necked Turtle© J. Simón Tagtachian To see a turtle hiding its head into the carapace when it feels threatened is not remarkable, but the way they do it is what makes the difference between the two suborders of turtles. Turtles and tortoises belong into the Order Testudines, which subdivides into Pleurodira (side-necked) and Cryptodira (hidden neck). The turtle of the upper photo, a side-necked turtle
Phrynops hilarii, hides its long neck by folding it sideways. Pleurodira are found only in the Southern Hemisphere. The turtle below, a painted turtle
Trachemys scripta dorbignyi belongs into the Criptodira. It pulls it straight back into the carapace. In both cases vertebrae have adapted to move in such a way. This little turtle was found by workers of the Plan Obra who gave to the personnel of the Reserve fearing it could be stepped on by visitors.

Saltator aurantiirostris
Pepitero de collar/Golden-billed SaltatorThe napping saltator was perching on a branch and suddenly began to bend to an almost horizontal position with its head leant over a leaf. At first we thought it was sunbathing, then we feared it would fall onto the ground completely asleep! It was quite funny. © Carlos González Ledo If you want to know why a bird does not fall, read Perching and tendon locking mechanisms

Rufous-bellied Thrush
Turdus rufiventris
Zorzal colorado/Rufous-bellied ThrushI was on the Lizard Path on my way to Viamonte when this Rufous-bellied Thrush unexpectedly emerged from the vegetation. Strangely enough it had more or less the size of an Eared Dove... The bird perched for some seconds on a branch right in front of me and moved very restlessly with an open bill but emitting no sounds at all. It is difficult to explain its behaviour but if one "anthropomorfizes" it, I would say it wanted to puke and did not manage for some reason. The bird dived into the bottom of the vegetation. I waited and searched for it but it never appeared. I believe that the explanation might lie in some sort of intoxication (we will never know it) and as I can see it the general aspect of this bird does seem very promising.... © José Luis Blázquez

Two birds building nests
House Wren
Troglodytes aedon
Ratona común/House Wren© J. Simón Tagtachian The House Wren is sort of lazy to build nests. It makes do with any hole at hand, either natural or artificial. It arranges some vegetal material and that's that. We saw it carrying material into this hole.

Small-billed Elaenia
Elaenia parvirostris
Fiofío pico corto/Small-billed Elaenia© J. Simón Tagtachian

This elaenia is carrying a web in its bill. Spider webs are used to stick the materials nests are built with. The nest is a tidy and elaborate cup which sits on branches. The inside of the nest is lined with feathers to cushion it. The feahter the bird has on the tail might have got attached while working in the nest.
