Procelsterna

' Procelsterna ' is a genus of birds in the tern family. It consists of two species, which are sometimes considered to be conspecific.

  • Blue noddy, Procelsterna cerulea
  • Grey noddy, Procelsterna albivitta

The grey noddy is sometimes considered to be a morph of the blue noddy.

These are grey-plumaged terns of tropical oceans, which nest colonially. They feed on small fish picked from the surface.
