Cogswell 1949 Larus occidentalis July 17. OT. Lobos, Monterey Co., Calif. - many 3/5 to 3/4 grown young roaming about the upper slopes of the nearer bird islands off the south shore of the peninsula. Several of them pecked at the bills of adult gulls near them, but I saw none actually being fed. The short tail of even the 3/4 grown ones gives them a dumpy appearance. The general tone of their plumage is decidedly darker, especially about the head & breast, than that of the "immature" (probably 1yr. old) gulls now frequenting Monterey Bay. Several of the juvenile gulls here today were trying their wings, but none were seen to fly.
