Noddies (seabirds - terns

Body
Terns

Grey-backed Tern, Onychoprion lunatus

 

Nesting Grey-backed Tern Noddies are members of the tern family Sternidae in the genera Anous, Procelsterna, and Gygis.

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.

 

Description

They are a tropical group, characterised by the notch-wedge shaped (not forked) tail; coastal and pelagic oceanic.
