Red-throated Loon juvenile 11/24/18

Red-throated Loons are more common than you might think, but you have to distinguish them from the larger Common Loon. They are both smaller and sleeker, and tend to ride lower in the water. Note especially the thinner bills with a slightly upturned and more pointy appearance. Juveniles like this one are told by their overall dull gray and indistinct field marks, while winter adults have bright white throats, necks, and undersides but with dark gray uppers. The red throat is seen in both sexes, but only in the breeding season.
