A mother bear was filmed earlier this week climbing up a tree to watch over her cubs as they fed.

The scene was filmed in the garden of a home near Pennsylvania on May 3.

"Why don't you get those babies up there first, what's she doing?" says a female voice in the video. "Babies aren't moving. She knows we're here, too. I'll guess she'll warn them."

A man can be heard saying: "She's getting a better view."
