Abstract:  [eng] Regression of the House Sparrow (Passer domesticus) at the Dragonera's island. After the six consecutive ringing campaigns durin g the post-nuptial migration to the Dragonera's island (Balearics) it has been observed a progressive reduction of the captures of House Sparrow (Passer domesticus) up to the extinction of its colony in 1992.
