Noddies are members of the tern family Sternidae in the genera ''Anous'', ''Procelsterna'', and ''Gygis''. They are a tropical group, characterised by the notch-wedge shaped (not forked) tail; coastal and pelagic oceanic. Studies of mtDNA sequences (Bridge, 2005) have shown that the noddies are at least 2 groups that split off early from the ancestral terns at different points of time; the relationships of ''Procelsterna'' were not researched for lack of samples. It seems to represent either a third lineage linking the noddies and the marsh terns, or is closely related to ''Gygis''. Genus ''Anous'' * Brown noddy or common noddy, ''Anous stolidus'' * Black noddy, ''Anous minutus'' * Lesser noddy, ''Anous tenuirostris'' Genus ''Procelsterna'' * Blue noddy, ''Procelsterna cerulea'' * Grey noddy, ''Procelsterna albivitta'' Genus ''Gygis'' * White tern, ''Gygis alba'' * Little white tern, ''Gygis microrhyncha'' Noddies are reportedly a dietary staple on the island of Nauru. ==References== *Bridge, E.
