If you missed the rawstory report on the CBC news, here's a link:

CBC’s The National reports that tens of millions of birds are disappearing across North America. The video is from CBC’s The National, broadcast on December 28, 2007

Interesting. But is it just another scare story?

But I went to the Audubon site and made a graph for a search on "Moorhen". The table showed a drop about 1980 to 0. Then I did a search on "American Coot". The table showed that the count for Coots had risen from 318 in 1980 to 634 in 2006. The bird she was pointing at in the video was a Coot and the Moorhen would be a rare bird in Ontario in any time period, as is the coot.

Near the end of the video, one of the ladies mentions Hermit Thrush in Nova Scotia. The Audubon site shows a count of 0 in 1980 and a count of 87 in 2006 in the province of Nova Scotia.

I wonder what the empirical data supports the claims made in the video. The historical data at Audubon indicates species are increasing in numbers overall.

Try some yourself at:

Also the trends here are mostly positive:

There was a huge study in 2004 that projected a large increase in the loss of species and the increase in the numbers of threatened species. Perhaps, the basis for the video was a misinterpretation of that work. You can read about it at: http://www.sciencedaily.com/releases/20 ... 023334.htm

Cheers,
Dennis

I missed this and just wanted to say thanks. Otherwise I would have not seen it and really wanted too. I found it very interesting and sad that so many don't know whats really happening in our world. We all go along untill there is a crisis then we go into action trying to fix what we've done. And some people don't relate that the changes in our world effect all things living and non.Thanks again for posting.

My bad!!. The sentence should read,
"Audubon indicates birds are increasing in numbers".

Other resear4ch indicates the number of species is declining.

How confident can we be that its birds increasing rather than bird counters?
