PAS – How they work
Farmers and breeders in the area provide the land for the PAS and contribute towards the provision of the carrion by providing, for example, animals that have died on their farms. These meat products not destined for human consumption are fed to the birds together with those from local abattoirs.
The technicians from TRENCA and Rural Nature, together with Endesa, coordinate the entire process, monitoring the species and arranging the bird feeder maintenance and cleaning tasks.
The technique for providing food has improved over the years. Currently focus on small and somewhat hidden pieces, which is what the cinereous vulture, the bearded vulture and the Egyptian vulture prefer. This ensures that it is not eaten by other carrion species that do not have population problems in the area, such as the griffon vulture, which eats large pieces in a group.
Environmental education and dissemination
The project for the implementation of Supplementary Food Points for necrophagous birds in the Pyrenees is related to environmental education. Throughout 2019, it has been disseminated in the schools and colleges in the area through workshops and teaching sessions. Furthermore, each year, visits are arranged for those interested in the project in order to learn more about necrophagous birds.
This project has become significantly relevant and has been published in important scientific magazines like the 'Journal of Applied Ecology' and 'Nature'.
The future aim is for these birds not to need the PAS for food and to be able to develop naturally. The PAS will continue to provide significant support for managing cattle or other dead animals, which is beneficial both environmentally and economically.
