Ringed Teal
Callonetta leucophrys
Pato de collar/Ringed Teal © Carlos Agulian If a duck in flight has a white circle on the wing is a Ringed Teal. This spot is conspicuous when the wing is unfolded and hidden when it is folded. Here the white spot is visible because it was preening itself
Silver Teal
Anas versicolor
Pato capuchino/Silver Teal © J. Simón Tagtachian Pato capuchino/Sivler Teal © J. Simón Tagtachian The differences between the male and the female of the Silver Teal are so subtle that they are considered a monomorphic species in guides. To begin with there is size, the male is bigger than the female, which is difficult to appreciate. It is easier to use differences in color. In these two photos three can be seen: the colour of the bill and the legs and the barred pattern of the tail The male bill is strongly coloured. That of the female is paler. Male legs are yellow. Female legs are grey. The barred pattern of the male tail is finer than that of the female.

Yellow-chevroned Parakeet
Brotogeris chiriri
Catita chirirí/Yellow-chevroned Parakeet © Nicolás Giorgio The Yellow-chevroned Parakeet belongs in the Psittacid Family, which comprises macaws, parrots and parakeets. This is the smallest psittacid (23 cm) which frequents Costanera up to now. Records are scattered throughout the year without a definite seasonal pattern. It is associated to the silk floss tree
Chorisia speciosa, the fruits of which are torn with the bill to extract the seed. The fruit is big like an avocado. It is 15 cm and hangs, which makes the parakeet pirouette to reach the seed. The fruit has a woody shell and is stuffed with silk fibers. This parakeet perforates it and separates the fiber to get the seed. In the photo the woody shell has recently come off since the fibers still keep the form of the fruit. It has not broken apart yet. Inside it plenty of seeds are found. The seed is black and half centimeter in diameter. The peel is discarded.

They were on an islet with a pair of Brazilian Duck (first photo). Both were immature.

Southern Caracara
Caracara plancus
CaranchoJ/Southern CaracaraJ CaranchoJ/Southern CaracaraJ We saw this juvenile caracara at the Viamonte Access at about 8:30. It was being attacked by two guira cuckoos and showed no reaction at all. It then flew some meters away and perched on a tree at two meters high. We took some photos. And so we did when we met it at 12:30 hs on another tree and at 5:30 in the nearby sanitaries. At first we thought it was ill but it seems this is the behaviour of juveniles. © J. Simón Tagtachian

Falaropo común/Wilson's Phalarope Falaropo común/Wilson's PhalaropeIn this small group not all the individuals have the same plumage colour. This is because they keep some of their breeding plumage and are changing into the non-breeding one. These birds breed in the Northern Hemisphere after which they migrate to the south. In the photo below the phalarope in the middle keeps the line which begins black in the eye and then turns chestnut. In non breeding plumage these birds are dorsally grey and ventrally white. © J.

Survey on the 5th of October 2013 organized by the COARECS 121 species were counted. With this fourth survey by the COARECS a year is completed. The recovery of water in the Coypu Pond attracted a lot of "old" species of water birds which have settled yet. That's way several were absent on Saturday. But there is a promising future which, I have no doubt, will catch up with the "wet" days. It is a matter of time.

Southern Lapwing
Vanellus chilensis
Tero común/Southern Lapwing© Eduardo A. Haene Lapwings build rudimentary nests on bare ground or short vegetation. Just a scrape lined with plant material. They lay three or four eggs which will hatch within approximately a month.They look after the nest very vigilantly. When they feel threatened they are either attack the intruder flying low with their menacing spurs or divert the observer's attention to another place.CR
Wilson's Phalarope
Phalaropus tricolor
Falaropo común/Wilson's Phalarope© Eduardo A. Haene A boreal migrant which flies from the Norhern Hermisphere till Tierra del Fuego by the Andean flyway. Some smaller groups deviate from the route and reach Buenos Aires. In bygone days it was common to see them in the ponds. This lonely individual is certainly one of the first to arrive. CR
