Red-footed boobies can be trickier to identify because they come in several different colors, known as "morphs". All red-footed booby adults have red feet, though! Pictured here is a white morph.

This bird has red feet and a white body, but it has more brown on
the wings than the first bird;
it is an intermediate morph
red-footed booby.
Even though this bird is very brown, it isn't a brown booby (no line across the chest and no white underbelly)! Look at those red feet and colorful bill; this is a dark morph red-footed booby.

Face coloration can vary among individuals! Red-footed booby sex can be hard to tell, but often males have more colorful faces during breeding. Pictured here is a male.
Notice the color in this bird is a bit more muted; it is most likely a female.
