How Many Kinds of Birds Are There and Why Does It Matter? Gifting at the American Museum of Natural History
For the new work, Joel Cracraft, George Barrowclough, and their colleagues at Nebraska University, Lincoln and Washington University examined a random sample of 200 bird species through the lens of morphology — the study of the physical characteristics like plumage pattern and color, which can be used to highlight birds with separate evolutionary histories. This method turned up, on average, nearly two different species for each of the 200 birds studied. This suggests that bird biodiversity is severely underestimated, and is likely closer to 18,000 species worldwide. more »

I gave up my car when moving downtown, so if you still drive, including "at night," you're my hero. Sorry if you're down in the dumps, but I'm looking for someone upbeat. You should be able to text. Please have a smart phone and know how to send messages. I love quality TV. If you haven't heard of Netflix, we're likely not a match. And if you don't have a sense of humor, we have nothing in common." more »

"Polluters would clearly be the ones who benefit from Pruitt being the Environmental Protection Agency Administrator. Regular Americans would be the losers. The head of the Environmental Protection Agency should be making sure that our air is clean to breathe and our water is safe to drink, not working to make sure polluters make more money." more »
