For several years I have watched crows congregate near the Bath House
Theatre at Green Lake, late every afternoon, then fly in a large crowd
towards the Arboretum.

Have recently noticed a similar daily commute along the West shore of
Lake Washington. I see them coming from the Matthews Beach area, then
continuing North; pretty much above the Burke Gilman Trail. It can take
several minutes for them to pass, some in groups of a dozen or more while
others are almost solitary.

I have been asked where they spend the night, but can only speculate. Any
info will be most appreciated.
