Combination of 3 colour-rings and metal ring.

note 1 : between years 2002 and 2008 :
left tibia : white ring. 
left tarsus : metal ring.
right tibia : two c-rings (dark-blue, white, black, dark-green, red, yellow, orange). 
right tarsus : nihil.

note 2 : between years 2008 to Feb. 2012 :
left tibia : dark-blue ring.
left tarsus : metal ring.
right tibia : two c-rings (dark-blue, white, black, dark-green, red, yellow, orange).

note 3 : after 2013 :

right tibia : two c-rings (dark-blue, white, black, dark-green, light-green, red, yellow, orange).
right tarsus : nihil.

note 4 : after 2018 :
left tibia : red ring.
left tarsus : metal ring.
right tibia : two c-rings (dark-blue, white, black, dark-green, light-green, red, yellow, orange).
right tarsus : nihil.

note 5 : After August 2023 :
left tibia : dark-green.

right tibia : two c-rings (dark-blue, white, black, dark-green, light-green, red, yellow, orange).

note 6 : violet/mauve/purple (V) colour that I think is distinct enough to be included as part of the combinations in order to increase the number of combinations with the latest GREEN code ring.

note 7 : some birds are fitted with geolocators. The first results are hopefull and we have discovered the breeding locations for six birds – two in Norway, three in Sweden and one in Finland close to the Russian border.
