 Annobón is home to the endemic Annobón white-eye ("Zosterops griseovirescens") and Annobón paradise-flycatcher, ("Terpsiphone smithii").An additional four endemic species inhabit two or more of the islands, including the Príncipe speirops ("Speirops leucophoeus") and velvet-mantled drongo ("Dicrurus modestus"), which inhabit both São Tomé and Príncipe, and the São Tomé bronze-naped pigeon ("Columba malherbii") which inhabits both São Tomé and Annobón.The Tinhosas islands are home to the largest seabird colonies in the Gulf of Guinea, with breeding colonies of sooty terns ("Onychoprion fuscatus", 100,000 breeding pairs), black noddies ("Anous minutus", 10,000–20,000 breeding pairs), brown noddies ("Anous stolidus", 4,000–8,000 breeding pairs), brown boobies
("Sula leucogaster," 1,500–3,000 breeding pairs) and small numbers of white-tailed tropicbirds ("Phaethon lepturus").
