Similar species:

The Red-footed Booby is smaller and faster-flying than the other boobies. Adults have diagnostic red feet and pink-based bills. When flying, adults of the white phase are similar to the Masked Booby but have white tails (usually) and white inner secondaries. The combination of the brown body plumage and the white rump and tail is characteristic of the dark phase Red-footed Booby. Immature Red-footed Boobies are obviously darker than all but the immature Brown Booby but lack the underwing pattern and breast demarcation line.
