Fig. 1.

Distribution and abundance of the red kite breeding population per 10 × 10-km square in Spain. Data were obtained from the species censuses in 1994 (15) (A) and 2014 (16) (B). Changes in occupancy and abundance per square were obtained by combining both censuses (C). Red kite populations in the Balearic Islands and Doñana (within dashed circles) were excluded from the analyses (see Materials and Methods). The global distribution of the species according to the IUCN (24) is shown in the map at the top right. (Red kite image credit: Public Domain Pictures/George Hodan.)
