A mother is pictured here with it's chick. Notice the mostly yellow bill with a black spot in front of the eye; that mark helps identify the bird as a female.
This bird has a mostly yellow bill, but is missing the black spot in front of the eye. Notice it has an almost blue mask closer to the eye; these clues identify it as a male!

This bird is also a brown booby! But it is a different subspecies, Brewster's brown booby, found generally around the Pacific coast of Mexico. Males in this subspecies have a gray/white head like this flying bird.
