Ceryle alcyon. Maine (Lake Umbagog). 1880. June 22. Set D=6. Fresh. Hole in side of sandy mound in pasture, penetrating horizontally about five feet; eggs laid on a bed of fine fish bones; the male caught on the nest; upon examining him I found that he was incu- bating. This nest was in Abbott's pasture. There was no bank proper, the birds having simply pierced a hole in the side of a little mound where the earth had crumbled somewhat. (Taken by Olga Endicott) 1882. Oct. 9-22 Common during our stay but their numbers diminished towards its close.
