We catch and ring birds on behalf of the British Trust for Ornithology (BTO) and all data generated is submitted to their National Database to study aspects such as breeding success, winter survival rates, population changes etc.
We carry out the ringing sessions at 8 sites located in NE Hertfordshire, South Cambridgeshire and NW Essex (situated between Royston and Saffron Walden).
We meet at dawn on any day of the week when the weather is suitable (low winds and no rain) and run the sessions for 4 - 6 hours. We try to do 2 - 3 sessions per week as weather conditions allow.
