During the release in which Pilar López Partida, major of Valdemorillo, and Carmen Villanueva, councillor of Environment participated.The 26th February a Red Kite was released. This individual entered the Hospital of GREFA on the 10th of June of 2007, because it was taken illegally from its nest in Villanueva de Perales, a village on the SouthEast of Madrid´s province. It was a surprise to see it in a cardboard box that was left by the people that took it at a petrol station of the M-501 road. It appeared together with its brother that, unfortunately, died in GREFA due to the severe lesions with which it came. The survival Kite has stayed a long period in a rehabilitation process.

After a period of recovery where different veterinary and rehabilitation treatments have been necessary, the Red Kite (Milvus milvus), a species declared "In danger of extinction" throughout the country, was released in the village of Valdemorillo. Sponsored by the Council of Valdemorillo and baptised with the name of BLAS (patron saint of this village) was released by the major Pilar López in an act in which the citizens were also implied in the conservation of biodiversity and protected species, at the same time, we denounce the behaviour of some people completely non-respectful with the conservation of our fauna.

Blas, the Kite sponsored by the Council of Valdemorillo, with a radio-transmitter, incorporates to the study the GREFA does with this species...In this way, the individual released has passed to be part of the program of study and monitoring of the species that is taking place as part of the measures destined to the conservation of the populations in Madrid, where it has suffered a severe descent during the last years. In order to monitor this individual, it has a radio-transmitter that will give us information of different aspects of its ecology and biology from the moment of its release, and so we can act quickly if any threat appears. With this, six individuals have been marked with radio-transmitters; five of which with GPS satellites. One of these individuals ended breeding at the Guadarrama Range, two of its descendants were also marked with GPS satellites.
