Birds, along with chimps, elephants and dolphins are the few nonhumans that can recognize themselves in a mirror. (Helmut Prior)
Add a bird to the short list of animals that recognize themselves in a mirror. Only a few nonhumans have passed that intelligence test, including chimps, elephants and dolphins. Researchers in Germany say European magpies also have self-awareness: two birds were marked with a colored dot, which they ignored until placed in front of a mirror; then they tried to remove it.

Only the ones that get too near a wind farm die from barotrauma. The bats dying from the fungus is a different problem. You probably heard of this recently because a USGS scientist (see http://www.usgs.gov/newsroom/article.asp?ID=2058) identified the fungus and published the news a few weeks ago.

Are all bats dying from "barotrauma"? I had heard that it was a fungus killing them. We saw very few bats this past summer.
