Sumario:[EN]: The Bearded Vulture’s long breeding cycle requires that, in the Pyrenees, egg-laying must occur during the period from the last week of December to the first week of February. Fledging takes place during the second half of June or the first week of July. This note documents a case of late egg-laying and fledging in a polyandrous trio of Bearded Vultures. In 2002, a clutch of one egg, was laid between February 13th and 16th. Hatching occurred between April 6th and 10th, and the chick left the nest between August 18th and 20th, at 130-134 days of age. This case is one of the latest successful clutches observed and the latest documented fledging on the southern side of the Pyrenees.
