Dear David Trently:
Your credibility among the birding world
would be greatly enhanced
if you would refrain from posting to TN-Birds on
April Fools day. For that matter, mine would
also. There was a better report than your
"McDonald's" Weaver-Finch going around
last April 1. :-)

Subject: [tn-bird] Interesting magazine article
>
> On Saturday, I received my May issue of "Avian Nomenclature" magazine and
> read a very interesting article. I had been wondering about this
> possibility, and it had been discussed a couple years ago on the BirdChat
> listserve - we didn't know someone was actually researching it. The
article
> is titled, "A New Split of an Old Species". It was authored by R. Warren
> McDonald and Brooks Jameson, researchers at the College of Trenton.
> Over a two year period, they studied the House Sparrow, Passer domesticus.
> The question they wanted to answer was, "Since this species has been
> separated from its original stock for over 100 years, is it possible it
has
> evolved far enough away from its parent strain to have become a separate
> species?"
> The researchers isolated pairs of these Old World finches in cages, 37
male
> American House Sparrows and 37 female European ones...and 42 pairs with
> European males and American females. Not one of the 79 pairs produced any
> offspring!! Only two pairs showed an interest in mating. (3 individuals
> died prematurely)
> They also did DNA studies to compare the genetics of the two groups. They
> found a significant difference in the DNA, enough for them to declare that
> these were now two separate species!
> Birders who travel to Europe and see the House Sparrow there can now add a
> new species to their lists!! The European bird will remain House Sparrow,
> Passer domesticus, while our American bird will tentatively become
> McDonald's Weaver-Finch, reverting to the 'finch' name, as that is more
> correct than 'sparrow', with the scientific name Passer oroarchicus.
> So, does that mean we now have on eless exotic bird out there?
>
> Remember, if you read it on the internet, it has to be true!
