Typically, when we see thousands of dead birds scattered across a natural space, our first thought is an oil spill, something like the recent Deepwater Horizon spill in the Gulf (the second anniversary of which we recognized this week). But another kind of man-made disaster is taking place in Northern California right now, and it’s having the same kind of impact on birds. The big difference is that this is one we can stop anytime we want. In an opinion piece a couple weeks ago, Audubon California Executive Director Dan Taylor urged the Bureau of Reclamation to send more water to avert disaster. It’s time they heeded his warning.
