I was in front of the new viewpoint sitting on the wall where the small tree is. Somebody approaches with a bittern in his hand. He was about to realease it on the ground below. I convinced not to since he told me 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 the Viamonte Access and give it to Reserve Personnel so that they act accordingly. I took some photos in the hand and in the cge. It seemed to be in good condition. CGL

Tropical Kingbird and Cattle Tyrant
Tropical Kingbird
Tyrannus melancholicus
Suirirí real/Tropical Kingbird10 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. Nvertheless, 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 a tree is a Tropical kingbird.
These photos help fix the differences. Teh 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.

Finding a house
When a bird does not build a nest and reuses another one's nest there is always conflict over property if the nest is still occupied. We know starlings reuse woodpecker's holes. Anyway here it laid some twings into a cavity on top of a broken trunk. The woodpecker had no intention to have the starling as a neighbour and ended up driving 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.
