Yeah, it is absolutely great news when we consider how several other populations are having huge problems these days.

Your suggestion about relocation problems are interesting. I know many species of birds have this preprogrammed home destination when they travel, but I honestly have no idea if this applies to the Adélie penguins.

who would have thought that you would have been able to count the number of penguins on a remote island by drones 10-15 years ago!!

That's true. Drones are turning out to be really useful these days, and I think they will just keep on increasing their usefulness as the technology increases their range, image resolution etc.
