The red-footed booby nests only on a couple of the smaller, more distant Galapagos Islands, and is therefore less observed by visitors (despite the fact that it’s actually more common than the blue-footed booby). And the largest, though least colorful of the three species is the masked booby, which is also common throughout the Galapagos Islands. A blackish, featherless “mask” surrounds its face and stands in contrast to the snow-white feathers on its body. The tips of its wings and tail are also black.
