The red-footed booby eats mainly fish, especially flying fish, it spots from the air before diving to catch it but also squids it catches at night by diving among school of squids.

The red-footed booby is well suited to diving thanks to its elongated bill, streamlined body and long wings which it wraps around its body before entering the water.

Reproduction

During the breeding season, the male attracts the female with a courtship display called « sky-pointing » where the male throws his head back until his bill points toward the sky.

The female lays only one egg every 15 months which is incubated by both parents for around 45 days. After hatching, the young chicks will fledge at around three months old.
