Agreed Steve. I don't think I ever suggested that every strange sighting
should be ticked. Clearly some discretion is required - and I think it's
up to the individual to decide what they tick and what they don't. As
for level playing fields and a standard list? Well, a person also has
the discretion to decide to play the competitive game or not. I know a
few people, who shall of course remain un-named here, maintain that they
adhere strictly to C&B and BARC decisions, yet have (as yet)
"unofficial birds" on their lists. I claim no such illusory rigour, I
tick what I've seen.
Tony.

For my part, I think that this bird is tickable (and indeed I did tick
the one I saw in the Melbourne Botanic Gardens about 4 years ago).
A house crow is hardly a common aviary bird; but it is known to stow
away on ships, of its own volition. I think in a port town like Sydney
it is reasonable to say that the most likely circumstance is that it is
a ship assisted arrival, not an aviary/cage escapee.
Is the debate that ship assisted arrivals are/are not tickable?
As far as the argument that we need a "self sustaining breeding
population" to tick a bird, this is clearly not true in all cases.
Single vagrant birds are ticked all the time.

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.
Regards,
Chris
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.
