The males supply the females with food, starting at daybreak to procure fish, often 

 at a distance of thirty miles from the breeding-place, and returning with it early in 

 the afternoon.

This Gannet is well-known and breeds on both coasts of Central America, but does 

 not extend to the shores of Mexico, where its place is taken by other forms. Salvin 

 captured a bird that flew on board the steamer off the coast of Salvador ^^, which 

 he believed to belong to this species ; it was not preserved, and may have belonged to 

 the allied S. brewsteri. We have examples of S. leucogastra from Half-Moon Cay, 

 off the coast of Honduras i*, but none irom Guatemala, and no doubt the bird recorded 

 by Count Salvador! ^^ from the Pacific coast of Panama is referable to it. 



The nesting-habits and eggs are similar to those of the other members of the genus 

 Sula.
