Keeping Lists

["Greg" <>]

Evan,

You must have a great memory if you can keep all of those lists in your 
head.  I envy you. As the number of lists grow and the numbers of birds on 
those lists grow you might find it necessary to have a written copy.  There 
is nothing more valuable than a written record of an interesting sighting 
from many years back.
Re. the call of the Ringtail Possum.  I have only heard a Ringtail call once 
and it was not a very conspicuous call.  This might be because they are in 
low numbers near my home.  Can you describe the call of the Ringtail?  We 
frequently have Common Brushtails 'coughing' here.
