Onychoprion fuscatus

[Draco]

I need some information about the physical and structural adaptations of the Onychoprion fuscatus.
common name: Sooty Tern.

I have already checked wikipedia but there is no information on what I want and the only text book I have is Biology 2.
Thanks in advanced.

Just to say that I have completed this peice of work now, although I chose a different animal to write about.

After this has been marked by my teacher I might post it here.
