Second group of butterflies of January
Sergio Cusano saw
Morpho epistrophus argentinus on the Lizard Path, but he could not take a photo. Last Saturday we saw it again but now on the Middle Path, but no photos were taken either. Let's be attentive. This is a 10-cm butterfly. Impossible to pass unnoticed. It is pale bluish white with a dark border

Caraú/Limpkin © J. Simón Tagtachian
The limpkin is ready to eat its favourite dish, the apple snail. Either visually or probing the mud limpkins look for them under the water. During the day snails stay submerged, that is why we do no see them. But we do find their empty shells piled in the "dining-rooms" or the clusters of eggs snails lay on vertical or bent surfaces, whether stems, walls or even on a bottleneck floating in the water.

Pato capuchino/Silver TealThis pair of Silver Teal swam past bobbing their heads and pecking at water in a very fluid dialog. With no further actions they moved on. The male is at the back. The lateral barred disegn is linea, whereas that of the femlae is scaled. As they are together difference in size is clear. Male's head is bigger and coulors more intense. Bars on the tail are to be taken into account. The male's is finer and the female's is thicker. © Carlos González Ledo

Tordo músico/Bay-winged Cowbird Tordo músico/Bay-winged CowbirdThe bay-winged cowbird looked for food on a cattail pile beside the wall. With the morsel in its bill it flew to a rosewood nearby, stayed there for a few seconds and crossed the street to reach another tree. Clear sign that it was food for a chick, otherwise it would have eaten it. After some attempts we spotted the nest in a poplar. He was reusing a great kiskadee's nest. We assumed the chick or chicks should be very little since we could not see gaping bills.

Absent during 2014 the Lake Duck came back to the pond. It feeds diving into water and can stay submerged for a while. The position of its legs is farther at the back, which makes it a good diver but a poor walker. It has a stiff tail which is normally kept erect when at rest. The underparts are whitish and there are no marks on the wings. Its light blue bill and its black hood may lead us to mistake it for the Masked Duck, which has recently appeared in the pond, too. With a more attentive look differences leap to the eye.

Before the drought the three species of coots were very abundant. The drought wiped them from the reserve. As ponds were fille with water they came back but with ups and downs. This is the first large group we see. Most of them are White-winged Coots but for a couple which seem to be Red-gartered Coots.
