Blue-footed Booby Sula nebouxii excisa Galapagos Islands, Ecuador. A mated pair. The female is on the left with the larger pupil (actually a dark pigmented area around the pupil, not a larger opening).

Nazca Booby Sula granti Galapagos Islands, Ecuador. Nazca Booby was split from Masked Booby (S. dactylatra) based on its orange (not yellow) bill and white (not black) central tail feathers. Both of these features are visible in this photo. On a few islands they nest together without interbreeding. Reference: Pitman, R. L.; Jehl, J. R.
