Similar species
At close range, the blue legs and feet are diagnostic. Immature boobies of other species are very similar to Blue-footed Boobies. Brown and Red-footed boobies have darker bellies. Masked Booby lacks the pale rump patch and has a more U-shaped demarcation between the dark upper breast and the white belly. Northern Gannets tend to lack the white patches on the nape and rump but at a distance may be inseparable.
