M Johnston 1948 Bonaparte Gull 19 Aug. Holkham Bay - Alaska. Beach just E of Point Coke. The B. gulls in the same size flock (50) as yesterday, were standing on the small point, or in the water such as they were yesterday. By 1/2 hr after high water they were gone. This is twice they have been congregated in the same place during the same activity during the same phase of the tide. Some did feed in the swrles that appear just off this beach on the incoming tide. On the outgoing tide the swrles appear 1/2 of a mile farther west. 20 Aug. Same - Swerls between Point Coke & Dumm Pen. The mammoth flock was feeding in a confined area 1/2 mi N of the swerls. They were massed so densely that the spot looked solid white. Most were floating + feeding, some flying. I shot a couple a few minutes later. The stomach was full of needle fish. Birds were floating in a flock when shot.
