In the case of Extremadura, although there are pre-2008 records of individuals of presumed Pyrenean origin, not a single satellite-tracked individual from this population has arrived in our region. On the other hand, there is a regular presence of Cazorla birds in the Gredos Mountains (La Vera, Jerte and Ambroz in Cáceres) and the north-east of Badajoz. Other parts of Extremadura visited by Lammergeiers include Las Hurdes, Villuercas and the river system of Tajo-Monfragüe, the central ranges of Badajoz and the Sierra Morena in Badajoz.
