There are six types of boobies, that have been seen on the oceans surrounding North America's southern waters, not including the Northern Gannet, which is part of their family. Boobies are large seabirds, known for their high dives from extreme heights into the waters below, shaping their bodies into dart-like forms in order to capture fish.
The boobies seen, are the Red-footed Booby, Blue-footed Booby, Brown Booby, Masked Booby, Nazca Booby and the Cocos Booby. The Masked Booby can be seen on its nesting grounds on the Dry Tortugas Islands, which are sand formed islands off the coast of the Florida Keys. Whereas the Cocos Booby, which has been separated from the Brown Booby as a sub-species in 2024, is found along the southwestern coastlines of the US, and southward into the waters of Mexico and Central America. The Nazca Booby has been separated from the Masked Booby, and is seen on the Galapagos Islands. All these seabirds can possibily be seen on the Pacific Ocean side, along the coast of Mexico, where they sometimes show up along the shores of the most southern states next to the seas.
ABA - American Birding Association This site represents an organization that maintains official records of all birds species that have been proven to have been seen inside the perimeters of the North American Continent and the surrounding bodies of water. Regular revised versions are posted to keep the bird list current at all times. This is the list used by all serious birders over their lifetime. You may be aware of the movie called the "Big Year". It was with this list that all the competing birders used in an attempt to set a new record as to how many bird species that could be seen by an individual birder in one calendar year.
