Rare hawk disappearing from Everglades

A graceful bird is disappearing from the place that gave it name, a victim of both nature and human meddling with the water flow in the Everglades. It's never a good sign when an animal disappears from the place that gave it its name. That's what is happening to the Everglades snail kite, an endangered hawk whose numbers are in free fall from the compounded impacts of back-to-back droughts and a long-controversial water management scheme intended to protect another equally at-risk bird.
