Red-footed booby

Description

The red-footed booby (Sula sula) is a large seabird of the booby family,Sulidae.As suggested by the name,adults always have red feet,but the colour of the plumage varies.They are powerful and agile fliers,but they are clumsy in takeoffs and landings.They are found widely in the tropics,and breed colonially in coastal regions,especially islands.The red-footed booby is the smallest member of the booby and gannet family at about 70 cm (28 in) in length and with a wingspan of up to 1 m (3.3 ft).The average weight of 490 adults from Christmas Island was 837 g (1.845 lb).It has red legs,and its bill and throat pouch are coloured pink and blue.This species has several morphs.In the white morph the plumage is mostly white (the head often tinged yellowish) and the flight feathers are black.The black-tailed white morph is similar,but with a black tail,and can easily be confused with the Nazca and masked boobies.The brown morph is overall brown.The white-tailed brown morph is similar,but has a white belly,rump,and tail.The white-headed and white-tailed brown morph has a mostly white body,tail and head,and brown wings and back.The morphs commonly breed together,but in most regions one or two morphs predominates;e.g.at the Galápagos Islands,most belong to the brown morph,though the white morph also occurs.The sexes are similar,and juveniles are brownish with darker wings,and pale pinkish legs,while chicks are covered in dense white down.The species has been recorded three times from Sri Lanka.In September 2016,a male red-footed booby was inexplicably found washed up on a beach in East Sussex,UK,5,000 miles from its nearest usual habitat.It was the first of its species ever recorded in the UK.The bird,later named Norman,was said by some to be exhausted and malnourished,though it flew onto the beach freely and was of normal weight when checked.He was brought back to health before being transported by plane to an environmental center in the Cayman Islands in December 2016,where it subsequently died before ever being released into the wild.In January 2017,a red-footed booby was sighted on the New Zealand mainland for the first time.
