Not my photos! I won't insult you with the potato quality image I managed to get of this bird. All credit to our guide Bjorn for these.
We saw this little feller flapping around by a waterfall in Snaefellsness, in eastern Iceland, last week, and we had trouble figuring out what it is. Bjorn thought most likely a hawk but I would love to know what kind exactly, especially as I don't find many hawks on lists of birds to see in Iceland.
I would say it was about as big as a pigeon, possibly a little larger, but definitely smaller than a gull. But assume some margin for error in my judgement.
(We weren't there for bird-watching, but we found an embarrassment of avian riches. Excluding this unidentified guy, a couple that I think I glimpsed but couldn't confirm, and several that our group definitely bagged but I didn't personally spot, I got at least 29 species, 20 of which were new to me!)
