Thanks for sending this to us all, Larry.

The number that really got my attention was for the Global estimate of Spotted owls : 16,000.

Not sure if anything about this has been posted before but Partners in Flight has put together a very nice display of their official population estimates for all the land birds that breed in North America. A lot of work has gone into this. You should check it out. http://rmbo.org/pifpopestimates/Database.aspx

Was wondering how many of these species are more numerous than our species is in the United States. I didn't use North America because I didn't know what to do with Mexico. With 312 million of us, and using the bird's total global population estimate, there are only two species that even come close. The American Robin is 310 million and you will NEVER guess what species on the list has the largest global population (860 million).

I know! Lets make a contest out of it! Send me your three best guesses without looking at the list, and anyone who gets it right will get a free pass to the Monroe Swift night out Community Celebration on Sept. 14.
