Hab. — From Texas to North Carolina ; California coast. 



The brown pelican is a permanent resident of our southern coast and the shores of the Gulf 

 of Mexico, also of California. Their nests are placed on trees, and also on the ground. Its 

 general habits are much like those of the preceding species, but their mode of procuring food 

 is quite different ; they dart upon their prey from on wing, frequently immersing the whole 

 body, but immediately rising on wing, dart down again and again until hunger is allayed. 



According to Mr. Audubon, its ordinary food consists of fishes of rather a small size, not 

 often taking any longer than its bill ; attached to specimen No. 9959 is a note by Mr. Cassidy, 

 stating that he has seen a fish weighing 2^ pounds taken from the pouch of one of this species.
