classification of birds as aquatic, marine or terrestrial [SEC=UNCLASSIFIED]

[Andrew Hobbs <>]

In addition to the suggestions of Philip Veerman you also need to be 
careful with your terms.  The word 'aquatic' is normally used to refer 
to any sort of water, and so for example, all marine animals are by 
definition also aquatic animals. The reverse is not true of course. I 
think you mean freshwater rather than aquatic.
Cheers
