Humane Behavior or Subverting Natural Selection?

Is this a smart way to spend "tens of thousands of dollars"? I realize that manatees are an endangered species but isn't the fact that a manatee is swimming off Cape Cod in October and apparently has no way of figuring out how to get back to its home waters an example of natural selection? When we give individual wild animals names, we're pretty much acknowledging that we don't really think it's wild anymore.
