buitre leonado
El buitre leonado es una de las aves voladoras más grandes de Europa y un carroñero fundamental en los ecosistemas mediterráneos. Estas aves sociales anidan en grandes colonias sobre acantilados y pueden planear durante horas aprovechando las térmicas sin apenas batir las alas. Las poblaciones de buitres sufrieron una crisis por el fármaco veterinario diclofenaco, que resultó letal al consumirse a través de cadáveres contaminados.
