[obol] California Gull Migration -- and my last report from Portland Airport

[Helzer, Dave]

OBOL,

This is my 3rd summer here at Portland Airport and each July there has
been a noticeable push of CALIFORNIA GULLS in July.  After being mostly
absent in May and June, they start moving through in July headed
downstream (westward) in small groups (5-15).  This morning a bigger
group of 110 was cruising down the Columbia River.  The only foraging I
have seen during this season is occasional aerial hawking of insects,
they generally are just cruising on by.

On a side note for Multnomah County birders, this will probably be my
last OBOL post from *inside the fence* at PDX.  I have taken a new job,
but I will miss birding this 2000 acre *prairie* in the heart of
Portland and sharing my sightings with all the local birders.  I expect
to keep getting reports of odd stuff out here from the wildlife staff
and will pass along local RBAs to OBOL in future.
