Tits

Combination of :
* one c-ring on one leg and metal ring on the other (pullus only)                    
OR
* 2 c-rings on the same leg and metal ring on the other (1st year and adults).

note 1 :  all pullus ringed the same year get the same c-ring. If returning as adult a second c-ring is added on the same leg (individually marked).
note 2 : all 1st year and adult birds have 2 c-rings in individual combinations, always on the opposite leg of the metal ring. None of our birds have a c-ring on the same leg as the metal ring.

note 3 : used colours are : white, red, yellow, light green, light blue, dark blue, orange, blue/yellow, black, red/white (note that two of the rings are 2-coloured!)
