Yesterday early afternoon investigated what was upsetting the crows near where I work, three crows very vocal in trees on NE 3rd ave. near Wasco (Convention center nearby). Found was a Barred Owl being harrassed, sometimes he flew from branch to branch, crows very vocal. Later, approaching 5pm, there were a whole lot of crows mobbing the owl, more than could be counted, who had moved to trees across Wasco, large mob who perhaps were gathering for roost later, highly agitated. First time saw an owl this location, is usually Red tailed Hawk that gets there attention. Bonnie Comegys blcomegys at gmail.com
