A golden eagle can detect movement from 10,000 feet in the air, and odds are it can also swoop in and kill it... It just flat out walks up to an animal protecting its cubs or stash and grabs them from under it... the golden eagles flat out ignore the rules of one of the most important games on the planet: don't mess with the bear. They can send full-grown grizzlies off in full sprint, presumably into the woods so that they could shit themselves in peace. They even kill honey badger!
Baby tortoises that have just hatched. We've had 29 tortoises hatch from eggs that were laid by one of the two female tortoises laid. Very intense care to raise them up to being one year old. But, we've had up to twenty-nine hatched and nineteen survive.
