What a throwback. I haven't thought about the movie Fly Away Home since I was a child. Really awesome to see people caring enough about animals to do stuff like this.

Hah, was just about to write about that movie too :D

Wow I haven't seen this movie in...about 30 years. We had it on VHS when I was a kid. Time flies.

With a population bottleneck of only 21 individuals, it sounds like their entire population is inbred. Even if it's hundreds of individuals now.

Same thing happened to Cheetahs and, to a greater extent, Florida panthers.

And possibly human ancestors (https://www.nhm.ac.uk/discover/news/2023/august/human-ancest...)

Seems you need more like thousands to ensure survivability, and it gets non-linearly worse as population gets smaller.
