– This tropicbird moults once every year as an adult, following a complex basic strategy. This prebasic moult is completed before courtship and lasts between 19 and 29 weeks, with most being completed in 24 weeks. Birds gain their adult plumage at two to three years of age.

– The red-billed tropicbird can reach speeds of 44 kilometers per hour when flying out at sea, cruising a minimum of 30 meters above the sea.

– Although it is a poor swimmer, the red-billed tropicbird feeds on fish and squid. The fish are usually small, between about 10 and 20 cm, although some caught are up to 30 cm.
