starting a cr-project : colours and codes have te be agreed with him , together
with “European colour-ring Birding”.

special note :
In June 2001 a Lesser Crested Tern (female) and a Sandwich Tern (male)
were ringed in the Banc d'Arguin nature reserve in France [44°35' N / 1°15' W].
The hybrid chick of the pair was also ringed in July 2001.
Since 2001 we study hybridization between sandwich tern and orange
billed tern on the Natural Reserve of Banc d’Arguin-Gironde-France. Are
ringed the breeding orange billed terns, the sandwich terns of the mixed
couples and hybrid chicks.
-
2001: 1 colour-ring on the left leg
(red or yellow), 1 metal ring on the right leg.
-
2002: no birds ringed.
-
since 2003: new ringing code:
o
left leg (exceptionally on the
right) : 2 colour-rings on the tarsus.
o
Right leg (exceptionally on the
left) : 1 metal ring on the tibia, 1 white ring on the tarsus.
Ringed birds - in 2001: 1 lesser
crested, 1 sandwich tern, 1 hybrid ; in 2003 : 1 unidentified orange billed
tern, 2 sandwich terns, 1 hybrid chick ; in 2004 : 1 hybrid chick.
note: one of the objectives of this study is the identification of the
hybrids, it is thus very significant that the observers of ringed birds make
the most precise possible description and if possible pictures.

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.
-----
2 rings (without code) on left tarsus and metal ring
on right tarsus.
