Loon; Great Northern Diver
7. Gavia immer. 31 to 35 inches.
In shape and motions the loons very much resemble the grebes, except in size, being much larger. The common loon is the most beautiful of them all, having a velvety black iridescent head with slashes of white on the throat and neck and spots of white on the wings and back.
Nest.—Usually built under some shelter of bushes or rushes on the edge of some of the larger ponds or lakes. The two eggs are a yellowish brown, with black spots (3.50 × 2.25).
