Bye, Bye Birdy. Climate Change Pushes Migratory Birds North.

We recommend this article in Bloomberg press reflecting the impending effects of climate change on birds. A relevant comment by Mike Di Paola, the article's correspondent:

"My first reaction to the findings was, so what? It doesn’t necessarily mean that migratory ranges are shrinking or that bird numbers are dwindling. What we are witnessing, however, is symptomatic of much bigger problems.

The birds are reacting to global changes that ecologists believe presage chaos at the ecosystem level. A warmer climate will alter vegetation, the availability of prey and a thousand other habitat features too complicated to predict.

“Because species respond individually and in very complex ways, we expect that ecological communities will start to tear apart,” says Burger. “This is one of the things we’re worried about.”

Repeat: "...we expect the ecological communities will start to tear apart." This is a very profound issue.
