Bird ringing is a basic tool used to find out about specific aspects on the ecology and biology of the different species which later could be applied to their conservation. The ringed birds, in this case the Barbary falcon (Falco peregrinus pelegrinoides), will provide valuable information on juvenile dispersal, philopatry, survival, mortality, etc., which will help to increase current knowledge that we have on this protected raptor in the Canarian archipelago. The program, authorized by Dirección General de Lucha contra el Cambio Climático y Medio Ambiente del Gobierno de Canarias, has already started in Lanzarote and Tenerife, and will probably be implemented on other islands in the coming years. We are grateful for the invaluable help of Gustavo Tejera (ornithologist from Lanzarote) and, as on previous occasions, the team of professional climbers, Javier Martín-Carbajal and Juan Zamora.

We implore ornithologists, birdwatchers and nature photographers to send us data referring to any observations of these ringed falcons. Please send all information (ring code, date, location, photographs if possible, etc.) to Manuel Siverio (msiverio@gohnic.org). Many thanks for your collaboration.
