can now be seen in cities like Barcelona and Madrid and is gradually being reintroduced peregrine falcons in our cities as the last link in the food chains of large cities. The reintroduction is a slow and complex and not always provide satisfactory results in biology there is always a random component that escapes us. As I say it is an arduous and expensive as each pilgrim chicken can cost in the order of € 600-800, and unfortunately, sometimes just the effort of weeks raising chicken to die in their first flights hit or victims of disease.
peregrine falcon (Falco peregrinus) soaring through the air. The hacking technique today is the most effective method for reintroduction of captive-bred individuals in nature.
This technique has several phases: Keep chickens indoors but where they can see what surrounds them. A probation when they are feathered, where they can leave the premises but they are still feeding inside the cage, so as to maintain a link with the precinct in which they develop. And finally the food is reduced once they are capable of short flights that will become increasingly independent.
The Hacking has been used successfully in other cities and in recent years has taken place in Valencia in order to observe the flight of the stranger in the sky in Valencia.
The introduction of a super-predator such as the peregrine falcon will bring a better balance in the ecological systems of the city and contributing to biological control of some species from a time now they are becoming true public health problems that make the control of their populations by the municipality of Valencia is a real headache.
