Sandwich Tern

White ring with a black three alpha code -starting letter 'C'- (on left tibia or tarsus) and metal ring (on right tibia or tarsus).

note 1 : 16 birds ringed during 2012 in the Languedoc, France.

Dark blue ring with a white 3 alpha code (3 letters) and metal ring (on other tarsus).

note 1 : Always letter 'N' on first position; followed by one letter and one numeric (e.g. NV2 or N2V); or one numeric and one numeric (e.g. N12); or one letter and one letter (e.g. NVT)

note 2 : Always letter ‘H’ on first position; followed by one letter and one numeric (e.g. HV2 or H2V); or one numeric and one numeric (e.g. H12); or one letter and one letter (e.g. HVT)

note 3 : Always letter ‘J' on first position, followed by one numeric and one numeric (e.g. J12); or one letter and one numeric and a ‘.' [dot] in the code in a random position (either between first and second digit, or between second and third) (e.g. J.2T or J2.V); or one letter and one letter (e.g. JVT)

note 4 : a joint project of the Research Institute for Nature and Forest/INBO, Bureau Waardenburg and Ringgroup Delta. This project started in 2010 and each year (except in 2011) both adults and juveniles have been colourringed.

note 5 : we use colour-rings in order to gain information on migration, habitat use, juvenile dispersal, age of return and recruitment to the breeding colonies in the southwest of The Netherlands or beyond.

note 6 : used letters are : A, C, F, H, K, L, N, P, R, S, T, V, X, Z.

note 7 :

Yellow flag with a two alpha-numeric code.

note 1 : project starts during summer 2012. The aim is to study the sandwich terns that appear in the south western Sweden in late June and then spend the summer.

note 36 : 

Combination of a white 3 alpha code ring and a combination of two c-rings and metal ring. 

* 2010.
left leg tarsus : orange/dark-blue.
left leg tibia : nihil.
right leg tarsus : white ring with a black three alpha code (first letter A or B).
right leg tibia : metal. 

* 2010.
left leg tarsus : dark-green/red.
left leg tibia : nihil.
right leg tarsus : white ring with a black three alpha code (first letter A or B).
right leg tibia : metal ring. 

* 2011 :
left leg tarsus : white ring with a black three alpha code (first letter B or C).
left leg tibia : nihil.
right leg tarsus : white/metal.
right leg tibia : nihil. 

Combination of 3 rings : a yellow ring over the metal ring (on right leg) and

1 ring (on left leg).

note 1 : one aim of this project is to study the moult of the Sandwich Tern and the use of the moulting stages for ageing. Another aim is to find out from where the resting birds at Falsterbo originate. During the period 1997-2002 some 400 adult birds have been caught.

note 2 : during 2001 following codes were used: right tarsus : yellow ring over metal ring and left tarsus : red ring.

remark : during 2001 two birds were ringed with a dark-blue ring (instead of red) outside the Falsterbo peninsula.

note 3 : during 2002 following codes are used : right tarsus : yellow over metal ring and left tarsus : white ring.

remark : some birds can be ringed during 2002 with a third ring on the left tarsus.

Blue ring with a white 3 alpha code (starting letter 'I').

note 1 : used letters are A,B,C,D,F,H,J,K,L,N,P,S,T,V,Z.

note 2 : only adult birds are ringed near the Saline di Comacchio, Po-delta by Adriano Talamelli.
