THE OCCURRENCES OF FOUR SPECIES OF PELECANIFORMES IN THE SOUTHWESTERN UNITED STATES

Abstract

The Brown Pelican Pelecanus occidentalis, Blue-footed Booby Sula nebouxii, Brown Booby Sula leucogaster, and Magnificent Frigatebird Fregata magnificens have all occurred in the interior portions of the southwestern United States. The frequency of occurrences, and the times of the year these birds appear is far from clear in the current literature.
