Hi all,

I'm ornithologist from Czech republic [far away from you] and
also leader of our national Group for research of Lari. Could anyone
sent me a short info about status of jaegers, gulls and terns in
Washington state [if possible also in Oregon]? I'm just interested
about notes like "common spring and autumn migrant" or "irregular
breeding bird in south" etc.
In our republic I study ecology of wintering Common [or
Mew] Gulls [Larus canus]. So I want to ask you to some more detailed
information about it from your state:
* is it also breeding bird as in British Columbia, Canada?
* is it common wintering in large numbers [how many?]
* does it prefer natural food resources or feed in garbage dumps and
behind fishing boats etc.
* what about relation to other gull species [in our republic it
feed and roost with Black-headed Gulls [Larus ridibundus] but
doesn't do so with "great" gulls like Herring or Yellow-legged.
* do you now something about its roosting sites [in CR it use great
water pools untill they froze].
* how is adult : second-winter : first-winter ratio [in our republic
changed from about 16 percent of adults up to about 80 - 95
percent].
* and finally, are there some changes in numbers [in CR great increase
from early 80s]
That's all, I hope somebody can help me with this.

Good luck
Martin
