The brown booby (Sula leucogaster) is a large seabird in the booby and gannet family Sulidae, of which it is one of the most common and widespread species. It has a pantropical range, which overlaps with that of other booby species. The gregarious brown booby commutes and forages at low height over inshore waters. Flocks plunge-dive to take small fish, especially when these are driven near the surface by their predators. They nest only on the ground, and roost on solid objects rather than the water surface.
The brown booby was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1781. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Buffon did not include a scientific name with his description but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Pelecanus leucogaster in his catalogue of the Planches Enluminées. The type locality is Cayenne in French Guiana.

Rare
Under 5% of wildlife watchers report a Brown Booby sighting in New York City on a given day, based on 61 verified sightings from GBIF citizen-science data. It is the 319th most-seen of the 359 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 Brown Booby in New York City 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 Brown 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.
17th of 17
Of the 17 cities where we can rate Brown Booby sightings, New York City ranks 17th at under 5%. The best odds are in Dakar (Senegal, about 20%), Rio de Janeiro (Brazil, about 10%) and Vitória (Brazil, about 10%).
GBIF citizen-science records
It is estimated from how often the Brown Booby is recorded against all the birds logged in New York City (61 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.
