Why is this so interesting?

Nature photographer Stan Mills also got footage of the family in early June.

His video shows the adult bear looking right at him while her cubs roll around playing.

Still, it’s possible that this mama bear may have a blended family.

That’s because it’s not uncommon for grizzlies to adopt cubs abandoned by their mothers.

Van Manen notes that two females with cubs have been recently observed near one another.

However, without genetic testing, it’s impossible to know whether all five cubs are related.

It’s unclear if they’re all related or if some cubs were adopted.
