Observation of the Lammergeier and Training Events in the Monte Perdido Biological Station (Ordesa y Monte Perdido National Park)

The “Monte Perdido Biological Station” in Revilla (Huesca), is located in the restored house “Juan Bernad” (16th century), an ancient construction of typical Pyrenean architecture managed jointly by the Foundation for the Conservation of the Lammergeier (FCQ) and the Dutch Foundation LammerGier Fonds (LGF). The purpose of the same is the development of training programs, technical seminars and residential courses, mainly related to birds and the conservation of their habitats. The EBMP is also used as accommodation for researchers and environmental professionals who devote their work to the monitoring of processes related to the study of the physical environment and the ecology of the Pyrenean mountain ecosystems, understanding as such the biological, geographical, geological and ethnographic aspects. As an “open-air classroom”, its use is also contemplated for other aspects related to environmental education, rural development, extensive livestock farming, and nature photography and painting, all of these being the FCQ and LGF’s social goals. It is therefore an eminently social action without a spirit of profit, consisting of the realisation of a centre for the promotion of activities of a technical nature, which will develop, in a responsible and altruistic manner, direct tasks of study, training, diffusion and environmental management in the Pyrenean area.

Revilla, in the heart of the Aragonese Pyrenees

The village of Revilla is located on the southern slope of the Sierra de las Sucas, at an altitude of 1200 m. It is situated in the municipality of Tella-Sin (Huesca), between the Mirabal-Escuaín gorges and the cited sierra. The uniqueness of its location, in an area of high natural value, i.e. the Ordesa y Monte Perdido National Park and the Sobrarbe region, which has a large part of its area included in the Natura 2000 network, make this place a point of extraordinary interest for groups interested in the conservation and study of the area´s natural heritage. The house is located in the heart of the Pyrenean population of Lammergeier, being one of the best observation points of this species in Europe.


The house can accommodate groups of between 15 and 20 people in shared rooms, each with a bathroom. It has a living room, dining room, kitchen, library, and conference room equipped with audiovisual media. It is, without doubt, an unbeatable place for residential stays for groups providing training of an environmental character since many of the activities can be done on foot from the house, thus reducing the need to make long journeys by vehicle. In line with the current programs to combat climate change, the house has solar photovoltaic energy for both electrical installations and domestic hot water.

The mechanics of meals, breakfasts, lunches, and dinners is guaranteed by a nearby local restaurant where we usually hire a “catering” service.
