Hermit Thrush. Note the brownish back with rufous tail.

Yellow-rumped Warbler. Note the yellow rump, white throat, and thin warbler bill.

Double-crested Cormorants, typically fly in loose flocks. Note their black forms with long necks.

Common Loon. Its head is to the top of the picture. A common view at area hawk watches, but bottom-side view not so common elsewhere.

Osprey, the flying M.

Also a Red-shouldered Hawk. From below, see the crescents on the outer edge of wings. It is also slimmer than the other buteos.

Sharp-shinned Hawk. Note the rounded wings and squared-off tail.

Northern Harrier. Note the white rump, long tail, and slightly-upturned wings

Broad-winged Hawk. You might think that the translucent patches are the crescents of a Red-shouldered Hawk. However, it has the broad bands and squat appearance of a broad-wing. I think that the translucence is due to molt. You don't see this in the fall.

Red-tailed Hawk. Note the broad wings, belly band, and reddish tail.
