Mr. Scott(1891) says: The birds appear every morning just after the sun is up and are then to beseen in the greatest numbers. By 10 oclock they have either gone far out to seato continue feeding or have retired to their roosting places in the cliffs. Theirabsence is noticeable from about the time in the morning indicated until justbefore sundown, when a few, not nearly so many as may be observed in themorning, are to be observed flying along outside of the cliffs. The native fish-ermen say that most of the birds return to their roosting places when it isalmost too dark to see. U. S. NATIONAL MUSEUM BULLETIN 121 PL. 27. Isabella Island, Mexico. H. H. Bailey.
