RFI re 4 letter alphabetical codes for birds

["Greg" <>]

Hi Ian,

Some years ago I was part of a team carrying out bird surveys for NSW State 
Forests  in northern NSW.  We used a four letter code for birds devised, I 
think, by State Forests.  It was interesting because there were records of 
Grey Falcons in the north coast forests, and quite a few of them.  The code 
for Grey Falcon was GRFA and the code for Grey Fantail was GRFT!
