RICHARDSON’S JAGER. 125 Jagers breed in the cold regions, nesting on rocks, or on the sand of the shore. They will fight bravely in defence of their young, no odds being sufficient to dampen their courage. The Cataract Jager is considered as formidable as the eagle. The Jager discovered by Dr. Richardson is one of the largest and most active of the family. It is about twenty-two inches in length. The plumage is of a brownish color. These Jagers breed in great numbers at the Barren Grounds, and may sometimes be seen in the vicinity of Boston. They harass the Gulls in the same way as others of the tribe.
