The Brown Booby is a sexually dimorphic seabird usually observed near the Dry Tortugas of Florida, where it perches on navigational markers or in trees.
It is suspected that it once nested in the Florida Keys, but only nests in Hawaii presently in the US. It will sometimes wander into inland areas of the southwest from western Mexico, namely around the Colorado River or the Salton Sea.
Similar to the Northern Gannet, it will plunge headfirst into the water while diving at an angle. It practices kleptoparasitism and will pursue flying fish from the air.
The thick cone-shaped bill is to be reckoned with if one is in the opportunity to rehabilitate this bird, as it can deliver a vicious bite that will assuredly draw blood. It will also do the same with other birds that have the audacity to be near it while fishing, for it will peck at them until they release their quarry.
A juvenile Brown Booby visited Oklahoma on August 16, 2018 on the property of the Dolese Sandpit in Dover. This photo was obtained by workers at that location. A second report of most likely the same bird was seen a day later in Bristow, OK. It is believed to have arrived in the area under storm conditions as a reverse migrant, which will happen to single, usually inexperienced migrants.

Another strong flier like the Magnificent Frigatebird, it is also silent, unless on the breeding grounds, and the only time they are on dry land is for purposes of reproduction.
These birds are extremely graceful fliers, but they are the most clumsy when it comes to takeoffs and landings. They must use strong winds and high perches as an assist.
