Carlos tells us that "I was sitting in front of the new viewpoint when somebody approached with a bittern in his hand. He was about to realease it on the ground below. I convinced him not to. He said he had been handed the bittern a short time ago and did not know whether the animal was able to feed by itself. I told him to take it to the Viamonte Access and hand it to the Reserve Personnel so that they it should be reinserted accordingly. I took some photos as he held it and in the cage. It seemed to be in good condition.

The first family was sailing from Brasil to Viamonte. After I had seen the bittern I found the second family ten blocks away. At first I thought it was the first family which had reached there, but right away I remembered that the number of cygnets was smaller.

These two tropical kingbirds arrived at this tree very noisily chasing one another. They always kept their positions but the arguments were in a loud voice, opening their wings to intimidate and showing their crest. So they came, so they were off.

Tropical kingbird and Cattle tyrant

Tropical Kingbird
10-10-16 © Hugo Aguilar
First sightings of the Tropical Kingbird of this season. The Tropical Kingbird comes to the south of Southamerica to breed in summer and the reserve is one fo the chosen places. It may be confused with the Cattle Tyrant which lives all year round in the reserve. They have different habits, the cattle tyrant is terrestrial and the tropical kingbird is always in trees. Nevertheless, now is breeding time for both species and it is common to the see cattle tyrant up in trees, because it nests there. That is to say, we cannot be certain that what is up in a tree is a Tropical kingbird.
These photos help fix the differences. The bill, the grey colouring, colour of the upperparts, etc. We must pay attention to all of them because they are not always very exposed just like in theses photos.

The European starling uses woodpecker's cavities to nest. It the nest is acte the starling has no problem to evict the occupants. It is very aggressive and ends up by winning. However, here it is putting some material in a natural hole of a tree near a woodpecker's nest. The woodpecker did not want to have the starling near and successfully drove it away.

These distorted and reddish leaves are the signs of a disease caused by the fungus
Taphrina deformans. The fungus infects new tissues which are exposed when shoots open. It develops in leaf cells and stimulates them to grow bigger than they should rendering this puckered appearance. Leaves become reddish because of the red pigments of the plant accumulated in the distorted cells. It can also attack flowers and fruit.
It is a very common disease which if it persists it ends up affecting the growth of the tree and its productivity.
