I have not confirmed a successful Red-shouldered Hawk (RSHA) nest in Multnomah County but I observed an adult working on a nest along NE 33rd Ave west of PDX in ~2010 in the days before leaves obscured the view of the nest. Although I made repeated visits to the area I was unable to determine if the nest was used. I have banded two hatch-year RSHA near PDX - one in mid-August 2015 and one in early September 2005. I keep looking but haven't found an active nest yet.
