Jeff Gibson is so pleased that no bird savant came forward with the correct guesses, because, unknown to Larry, the only case of anything I have, is a case of No Dinero - maybe you've tried it. The only bird I even guessed right was Flammulated owl, so I suppose I don't even have to buy myself a beer, thus saving money I don't have.



Jeff Gibson,

beerless, but not birdless, in

Port Townsend Wa.

See how many of these ten species you can correctly match with its population estimate. If you have no fear of humiliation post your list to the entire group.
