George,

Where and when did I come into this equation? I don't remember this 
conversation. Anyway, I found the following on the ABA website:

Rule 2: The bird must have been a species currently accepted by the ABA 
Checklist Committee for lists within its area, by the A.O.U. Check-list for 
lists outside the ABA area and within the A.O. U. area, or by Clements in 
general for all other areas.

    B. Currently accepted by the ABA Checklist Committee means:

            (iv) An indigenous species which is reintroduced into an 
historic range of the species may be counted when the population meets the 
ABA Checklist's definition of being established or when it is not possible 
to reasonably separate the reintroduced individuals from naturally occurring 
individuals.

Rule 3: The bird must have been alive, wild, and unrestrained when 
encountered:

       B. Wild means that the bird's occurrence at the time and place of 
observation is not because it, or its recent ancestors, has ever been 
transported or otherwise assisted by man.

            iii) Birds descendant from escapes or released birds are 
considered "wild" when they are part of a population which meets the ABA 
definition of an established introduced population.

What does this mean? Hell if I know. Actually, I believe that Matt was 
correct in his response. Since these birds are descendants of a reintroduced 
population to a historic range, I believe the guidelines in Rule 2 apply to 
this. I believe that every indication is that these birds are indeed from 
Ontario and they have been accepted by the authorities there as established. 
If that is the case then the birds should be countable here as well. Even 
under Rule 3, established birds of introduced populations, would make these 
birds provided they are recognized as such.

As for the Whistling-Duck, well . . .
