Re: Caspian Gull colony at Lelystad, The Netherlands
May 1st I visited the colony again and found 10 nest locations of pairs of seemingly pure Caspians. At 6 of it, I was able to have a quick look in the nest. They all contained 3 eggs, of which one clutch was already hatched. Concluding from that, the Caspians are at least 3 weeks earlier breeding th...

Ringed l.michahellis x l.a. argenteus
Hi all, Yesterday we got this offspring of a known breeding pair michahellis x argenteus from 2013. This bird was ringed as a chick in the colony near Amerongen, Utrecht, The Netherlands on June 14, 2013 by Roland-Jan Buijs. He ringed it with black-yellow MT on the tibia. See also pair VI: http://bi...

Re: Breeding numbers of cachinnans in Germany
Thank you very much, Ronald! Sounds like an ongoing, fast expansion from Poland into Germany.

Breeding numbers of cachinnans in Germany
Hello,
I am curious for the most recent number of breeding pairs of cachinnans in Germany. I couldn't find any up to date information on the web so far. Anybody?
Thanks in advance!

North Sea - pelagic
Apperently, the larus cachinnans could be a marine bird in winter. During a pelagic boattrip not far from the coastline of Texel, we found up to 14 different birds! One of it was ringed as PLVE [yellow], a well-known bird that has spent its first winter in Amsterdam. The table of today: Caspian Gull...

Re: Limburg 28 03 2013
Theo, what about the unmoulted secondaries? They have quite clean blackish centres in my opninion. (cf. http://www.lou.bertalan.de/gulls/m_phi.php?bid=148&grp=cachinnans%204-5cy%20january-june ) I would expect it more mottled or streaked for 4cy argentatus. Also, the tibia looks quite long and the b...

Re: Argentatus with clipring - tayeri pattern
Thanks Peter and Theo. Our first impression was cachinnans either. But I only had my binoculars and camera, since my scoop is in repair. I dind't know the p5 thing and was confused by the pattern. I guess it must have been Poland again. Nevertheless, it was the first time I saw a pair of cachinnans ...

Argentatus with clipring - tayeri pattern
Today me and Frank Majoor observed a pair of most likely argentatus Herrings on the dump of Barneveld. The male was wearing a clipring at the left tarsus. We were not able to read it due to the distance. While approaching the birds, they flew off. Interestingly, the male was showing a tayeri-patter ...
