Subject: [obol] Crows over NE Portland
We counted 1,045 crows flying over our postage stamp yard a block north of
the Alameda ridge in NE Portland last night between 8:07 and 8:47 PM. We
can see less than a block's worth of sky with the buildings around us, so
this is a tiny fraction of the total crow commute. We don't often conduct a
thorough count of this daily commute, but the last high count I remember
was about 4 years ago when we counted 525. Not very scientific, but it
appears crow numbers are increasing in Portland.
