Well, these pictures don't do this bird justice, but because Baltimore Orioles (Icterus glabula) are rare in Sonoma County (there are only ~7 records), and because this is the first one I've seen on Bodega Head, it seemed worthwhile to post a couple of pictures.
And, if you're interested in seeing this bird, it might still be possible. It seemed drawn to the eucalyptus flowers (see below), so perhaps it will stick around for a little while.
Photographed in Owl Canyon on 27 May 2015.
P.S. Madrone Audubon has a map showing Owl Canyon. And Colin Talcroft has provided an aerial view with a written description.
