Study area: Spain, Central and Eastern Pyrenees
Beginning of ringing and monitoring activities: winter 2005 (Eastern Pyrenees), summer 2012 (Central Pyrenees)
Ringing and field work activity: winter ringing and monitoring (Eastern Pyrenees; November-March), summer ringing (Central Pyrenees; July)
Main goals of the activities:
• Long-term population yearly monitoring to estimate demographic parameters and dispersion/connectivity among European populations;
• Site fidelity by using capture-recapture methodologies
• Genetic analysis

Ringing activity results:
More than 1000 ringed individuals in a wintering population of the Eastern Pyrenees
Ringing of few breeding individuals in the Central Pyrenees
Colour ring project:
2005-2009: colour rings in the Eastern Pyrenees at winter
Start 2013: PVC alphanumeric (3 digits) colour rings (yellow = breeding Central Pyrenees)
Start 2016: PVC alphanumeric (3 digits) colour rings (green = wintering Eastern Pyrenees)
European coordination of colour rings:
