Tits
Combination of :
* 2 c-rings on one leg and metal ring on the other (all ages).
OR
* one c-ring on one leg and metal ring on the other (pullus only and up to 2022).
note 1 : Since 2022 all birds have 2 c-rings on one tarsus in individual combinations, always on the opposite leg of the metal ring. Both legs are used to maximise combinations. None of our birds have a c-ring on the same tarsus as the metal ring. Before 2022 pullus were ringed differently (see note 2).
note 2 : Before 2022 all pullus ringed the same year got one and same c-ring. If returning as adult a second c-ring was added on the same tarsus (individually marked).
note 3 : used colours are : white, red, dark red (limited), yellow, light green, dark green (limited), light blue, dark blue, orange, lilac, black and 2-coloured blue/yellow and red/white.
