• Resumen

  • This is the sixth report published by the Grup Catala d'Anellament which covers the period 1991-93. A grand total of 96, 494 birds of 219 species have been ringed. During this period the GCA has been steadily increasing the number of birds ringed with a maximum in 1993 with 41, 848 birds marked. This trend is mainly due to the growth of the group with new ringers and the establishment of new campaigns and the collaboration in international projects like Progetto Piccole lsole and MRI-Program. This report summarizes all these activities and a selected list of controls and the most interesting recoveries
