After 7 months of hard work Julio Roldan and Walo Moreno (and co-workers) have ended the fieldwork by ringing the last chick in August. With a record number 60 occupied territories and 36 fledged young on Fuerteventura alone, 2016 was the most productive breeding season since the monitoring started in 1998 (60% of nest successful…
