What they're saying, for what it's worth (from the wired article): "The three dire wolves are now living in a 2,000-acre secure ecologic preserve, which is in a different location than the small enclosure that WIRED visited. Shapiro says that Colossal is not considering rewilding the dire wolves."

This helped. Thanks.

Those are some huge spots! Is that common for whatever region this is from?

I've seen this too and guessed it was raccoons.
