Red-footed Booby  |  

The Red-footed Booby is a slender bird with conspicuous red feet, long tail and a bill that can be blackish to pale blue. The eye is grey to grey-green and skin around the eye can vary from dark grey to blue to purplish in colour. Plumage colouring is extremely varied, with two main ‘morphs’ recognized: a white morph in which plumage is mainly white except the head area that is strongly tinged yellow, and black primary and secondary flight feathers; and an ash-brown morph in which feathers are pale to dark brown, except the tail which is usually white. A range of intermediate forms are also known and the two morphs intermix regularly. Males are approximately 15% smaller in body size than females with the approximate body length being 70–80 cm and an approximate wing span of 140–145 cm. At 1 kg the Red-footed Booby is the smallest and lightest of the Booby family.
