• Resumen

  • Results of the fourth year of the Balearic Common Birds Survey (SAC programme) are presented. 34 participants following 160 routes recorded a total of 79,108 birds of 147 species. These results are presented in tables, one for each period, with indices for making comparisons between years.

    We also present lists of more common species, in spring and in winter, with annual variation rates in the four years of the programme.
