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. brewstert. We have examples of S. leucogastra from Half-Moon Cay, 
off the coast of Honduras !*, but none from Guatemala, and no doubt the bird recorded 
by Count Salvadori 16 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.
