Wherever possible, please check any Willow Tits for colour rings, as there are 11 registered projects colour ringing Willow Tits across the country. To make full use of the information from colour ringing we need also need records of birds that were checked and turned out not to be ringed.
Please summarise all colour ring records on the Survey form.
Although they are not thought to travel far it is always worth checking the legs of any birds seen for colour rings. To be able to attribute a bird to a particular individual you will need to record what rings are present on each leg and the order they occur, e.g. left leg – blue ring above BTO ring and right leg – red ring only.
The numbers of rings on each leg vary between projects, and are detailed at the end of the methods.
