Michael -
I'm not sure if your post actually made it to tweeters. It was *not* on the
digests posted on the web, which is how I read it usually, so I am quoting
it here in its entirety.
Anyway, now that you mention it, the only definite Herring gulls I have
seen have been along more coastal areas and Greenlake. However, I don't do
much inland birding, especially in the winter, so most of my winter birding
is closer to the coast.
The NG bird guide shows the Herring gull wintering across Washington from
the northern coastal areas and then inland across the southern half of the
state. In a brief foray into the library I ran across a book summerizing
Christmas Bird Count data on most North American species. I only had a few
minutes and did not get a full reference, but it listed the Herring Gulls
across most of Southeastern Washington. It also listed their western
abundance at about 20% of the areas of greatest abundance (mainly the East
Coast). It made mention of them being found in the area of the Snake and
Columbia river. I'll try to get more complete info.
I noticed a couple of more recent posts listed many California or
Ring-bills, but onlu a couple of Herrings.
Anyone care to share a more first-hand view?
Gulls are a bear to identify, and I certainly meant no criticism by raising
the question. I'm just very interested in gulls, so the counts stood out. I
*try* to identify the juveniles, but don't claim much success.
And thank you for posting your weekly counts.
