Immature Cooper's Hawk or ?? in Help Me Identify a North American Bird Posted June 5, 2019 1 minute ago, hbvol50 said: Thanks. After going over the guides and my old photos, I came to the same conclusion. Not often that they are seen soaring. Perhaps not so often during the breeding season (though they still do soar), but I very often see Cooper's Hawks soaring, most often during migration and winter. I'd say 90% or more of my Cooper's Hawk sightings are soaring birds.
