Birdwatching of carrion birds. Depending on the time of year you may see one or more of the four European vultures: the Eurasian griffon vulture, the Eurasian black vulture, the Egyptian vulture and the bearded vulture, coinciding with feeding day, with the chance to spend 3-4 hours observing them. If you have time, there are also routes through the surroundings of the Buseu where an expert guide will take you to see other birds typical of the Pyrenees.
