I have to say first of all that for me is a great experience to banding these species because they are my weakness. Large predators at the end of the food chain and the ecosystem balancing species rapeces are the main characters of this post. This last week I was able to attend the banding of a kestrel nest in the meadow of Saler who had a chicken and two chicks banding owls in the end of Quart de Poblet.
In the first case takes 3 years breeding pairs nesting in this place and it is an infertile couple because it has never taken on more than 2 chickens, in both 2007 and 2008 was the start of 4 eggs, 3 of which were fertilized and 3 chickens always one died this year alone has lifted a chicken as well as later that the owners have told us the balcony had symptoms have suffered trichomoniasis, a disease that is now being widely among raptors and especially among kestrels because this year is to increase the incidence and chickens have come and kestrels that had to treat the disease. Fortunately for us the partner of the Gola of Puchol keeps returning to the same balcony every year and we can keep track of his productions, from here a sincere thanks to the owners of the floor from being so sensitive to the nesting of this bird of prey and to avoid inconvenience as far as possible.

In the case of owls bred in a nest box placed by a colleague of ours, Angel, who for several years has been concerned that these predators have places to nest safely. In this case the evolution in the 5 years that the owl breeding pair there is the following: 2005 (2 chickens), 2006 (3 chickens), 2007 (2 chickens), 2008 (not nested and the nest box was empty) , 2009 (3 chickens, one of whom has died).

ringed chicks had a good health, in the case of owls, both weighing over 80 grams. On the other hand, the situation of the nest box, very exposed and high temperatures reached in our visit favored the 2 owl chicks were ventilated. One of the possible causes of death may be just the high temperature at which the chicks are subjected together with the already mentioned trichomoniasis. S unattachable dead chick did not appear in the nest box, we thought it was the mother, continuing a pattern of hygienic behavior withdrew it from the box to prevent the arrival of insects that might endanger the rest of the brood.
