Thanks to the hard working volunteers at a Louisiana rehab center, there have been many happy endings – dozens of creatures ready to be released back into the wild. The director of the center says about 90 birds came in on Sunday alone, by far the biggest single day rescue of this disaster.

He joined us on Friday's American Morning to give us his assessment.
