Information from the ringer.

Sanderling B3WWRR.
I ringed the bird in Greenland and I am very happy every time I hear from one of “our” birds.
As you can already see on the PDF Jeroen sent the bird was ringed as a chick this summer and
already seen once before you observed it. At the time we ringed this bird it was the only one
together with a so far unringed adult. First capture was July 7 and the bird weighting only 9 grams
we applied only a metal ring that day but put a geolocator on the attending adult bird).
Only four days later we recaptured the bird weighting already 20 grams and applied color-rings.
