May 2014 – Champoeg State Park, Oregon
This appears to be a Cooper’s Hawk, perhaps a year old – still with juvenile plumage. These hawks are a bit hard to identify, but this one was surely too big to be the similar Sharp-shinned Hawk. Cooper’s Hawks are Accipiters, whose primary prey are other birds. They are quick and nimble hunters, swooping through the trees to snag their prey.

I’m fairly certain this is a Cooper’s Hawk… a female, possibly young male? The Sharp-shinned hawk looks similar, but is a bit smaller. So, without much else to go on, I’m going by size… even though there isn’t much to get a good scale on. If you have any other opinions, I’d love to hear them. Anyway, it was a fun little encounter – it just hung out on the lawn for a bit, then flew off.
