Pencil plant
Euphoriba tirucalli
Árbol dedo/Pencil plant© Dolores Fernández
Árbol dedo/Pencil plant© Dolores Fernández
This exotic plat has an unmistakable aspect. It looks like fingers of a hand. Leaves are difficult to see since they are very little and last a short time. The "fingers" are stems which photosintethize.
This plant belong to the Euphorbiaceae, a family which typically produces a white latex when cut. This plant's sap is very irritating and toxic. So, be careful. This plant is located at the former Covimet area. It was detected by Manlio who told us about these characteristics.

Masked Duck

Pato fierro M/ Masked Duck MAlec tells us that on Friday, 28th he saw at least 5 indivuals. The one in the photo was on the northern end of the water mirror at Coypu Pond. He then saw a female 100 meters to the south (though it was evasive it kept hidden in the vegetation). And 200 o 300 m even farther there were 3 males, where there is a clear recently opened. A sort of "street" perpendicular to the wall.

Limpkin

The Limpkin was an emblematic bird in the reserve while its favourite food, apple snails, grew abundantly. By 2000 waters of the pond got became salty enough for these snails to disappear since they are freshwater snails. So did the limpkin which became an occasional visitor. With fresh water back in the ponds apple snails repopulated the pond and today the limpkin seems settled. Up to 6 limpkins were seen at Coypu Pond. CR

Common Gallinule

A sequence of photos of a scene I witnessed at Coypu Pond of Reserva Ecológica Costanera Sur (RECS), en la Ciudad de Buenos Aires, Argentina. I do not know if a turtle or another animal tried to catch the chick from below and the adult went to rescue it. Everything began with the common gallinule running on water towards some bubbles where the chick appeared.

November 1st Sudestada On November 1st there was sudestada (heavy winds which when combined with rain flood coastal areas). The reserve opened at 9 but closed some time after due to bad climatic conditions. It was not raining, but winds were heavy. We walked to the Canal Carlota Roberts (former Canal Sudeste) and found the tide was in and very high and waves broke strongly against the coast. Interesting how tidily the river left the rubbish back on the coast.
