The red-footed booby (Sula sula) is a large seabird of the booby family, Sulidae. Adults always have red feet, but the colour of the plumage varies.

They forage by catching flying fish from above the ocean's surface and by performing shallow dives. They are found widely in the tropics, and breed colonially in coastal regions, especially isolated islands such as St. Brandon, Mauritius (Cargados Carajos shoals), and the Chagos Archipelago. Although its population is declining, it is considered to be a least-concern species by the International Union for Conservation of Nature (IUCN). It faces threats from climate change, competition with fisheries, human disturbance, and invasive species.
The red-footed booby was formally described by the Swedish naturalist Carl Linnaeus in 1766, in the twelfth edition of his Systema Naturae. He gave it the binomial name Pelecanus sula and described it based on a specimen from Barbados. The present genus Sula was introduced by the French scientist Mathurin Jacques Brisson in 1760. The word Sula is Norwegian for a gannet... Wikipedia →

Rare
Under 5% of wildlife watchers report a Red-footed Booby sighting in Singapore on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 238th most-seen of the 298 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Red-footed Booby in Singapore on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Red-footed Booby sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 cities where we can rate Red-footed Booby sightings, Singapore has the highest daily chance: under 5%. Next come San Diego (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Red-footed Booby is recorded against all the birds logged in Singapore (33 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
