Hi Tony,

I think Evan's point isn't that you left them out of your discussion, but
more do you have a reliable way of telling which is which?  For example, how
do you know someone didn't have a pet House Crow that escaped?  Bad example
probably but if I told you there was a Blue and Yellow Macaw flying around
in my back yard would you come and tick it?  What about a Java Sparrow?  Or
something really contentious like a Blue Rock Thrush?

I think it's important for each odd bird that is found to have the potential
that it's a caged bird that has been released or escaped assessed.  Which as
I understand is pretty much what we already do.


ps. while I agree with Evan about putting what you want on your list, that
only works if you're not competing with other twitchers.  If you are you
need to use the same rules or it's not fair.
