Hi Tweeters,
I am new to this, so forgive the format ...
Where I live we are overlooking the south central part of lake Sammamish.
(My condo faces north.) And all this month I have seen on sunny days
hundreds of medium sized gulls swimming in the lake in a certain area maybe
the size of a football field or larger. They arrive in the morning and leave
in the afternoon. While there, they seem to swim forward about 50 yards then
fly up, circle back, land and repeat the pattern. Endlessly. They dont seem
to be feeding, at least not that I can see with my binoculars. So I am
wondering who they are and what they are doing...?

Then one day, while this was going on, a flock of a hundred or more HUGE
gulls or large bent wing birds similar to osprey, appeared, swirling and
circling in a slow motion tornado ABOVE the gulls on the water. They seemed
to be interested in the smaller birds on the water, but I never saw an
attack or skirmish between the two communities as long as I was watching
them (about an hour). So I am also wondering who they are and what they
were doing.

This was a fascinating and unforgettable scene; I hope someone can shed some
light on what was going on.
Thanks,
Bill Austin
