ABSTRACT Aim We expand here previous own biogeographic work on the determinants of avian colonisation a major land‐bridge Mediterranean island. So far we have explained mechanistically high current rate island which proceeds by overflow mainland species with growing population trends and prior experience as winter visitors. However, focus historical factors that led to such rate. Location Majorca Island nearby Iberian coastal region equivalent characteristics (Alicante province). Time Period Twenty‐five years (1991–2015). Major Taxa Studied Birds. Methods compared pattern gain loss in Alicante during study period. Results found while only gained eight new lost one, none 21 breeders (odds ratio 2.6). The process gains 5‐year periods since 1991 showed nonlinear both regions, an abrupt decline starting 2006–2010 final stagnation 2011–2015, but just smooth recent slowdown (2011–2015 on). Taxonomic diversity colonising at family level, well habitat colonisation, were quite similar between larger body size more common Majorca. Main Conclusions conclude differential rates regions are consistent intense past defaunation resource‐poor (Majorca) modern rural flight happened simultaneously regions. While could be approaching theoretical carrying capacity number species, is farther from it. predict will continue gaining next few decades. Worldwide, further research comparing wildlife recovery intensity badly needed understand biodiversity processes.
