SEO-Birdlife
En la línea de la serie de monografías sobre censos específicos de la avifauna española que está llevando a cabo SEO/BirdLife, el presente documento representa una valiosa contribución al conocimiento y ulterior gestión de este grupo de aves, al recopilar de forma sistemáica y detallada la información más actualizada de las poblaciones de cinco de las ocho especies de gaviotas que se reproducen en España. También se recoge información sobre la evolución histórica de las poblaciones. Para cada especie estudiada se detalla la metodología de censo, la distribución, el tamaño de la población, la evolución demográfica, los parámetros reproductores y el estado de conservación.
