Why Have so Many Birds Disappeared From a Tropical Island in Panama?

The bird in the box is a Slaty Antshrike, deciding whether to make its cross-water flight back to Barro Colorado Island during our translocation experiment designed to figure out which species move on and off of BCI.

Remarkably, some species will not traverse 100 m over open water.

Two species never flew more than 30 m. D. Robinson
