Brown Booby: Seasonal Occurrence & Geographic Distribution

*Brown Booby Sula leucogaster

Lower Coast Status: Very rare (six records) in coastal South Texas. Most likely in summer and fall, but has occurred in all seasons.

TX Status: Very rare visitor to offshore waters and along the coast and accidental inland. There are 37 documented records prior to 2014.

Habitat: along the immediate coast, including Port Isabel, South Padre Island, and Boca Chica and Laguna Madre. This species has been found perched on rock jetties, channel markers, and on spoil islands; may occur on occasion in offshore and pelagic waters off the Lower Texas Coast.

Similar Species: Brown Booby can be distinguished from both Northern Gannet and Masked Booby by its browner plumage (dark brown breast and all dark back and rump) and yellow feet. Both Northern Gannet and Masked Booby show variable amounts of white in rump or uppertail coverts. Masked Booby always shows white breast.
