Birds are on the move
After the US Airways Flight 1549 which I discussed on 2/7/09, the New York Times reports that we are tracking birds by putting lightweight "backpacks" on them. In a separate article, we are finding out that because of global warming, birds are moving further north: "The boreal chickadee has moved 280 miles north, almost out of the range of the lower 48 states. The marbled murrelet, a seabird that breeds inland, has moved 360 miles north. The wild turkey has gone about 400." Such shifts in biotopes makes evident the nomadic character of the Animal Revolution.
