Mother duck bravely protects her chicks from attacking goose

While walking by Lake Murray in San Diego, California, a couple spotted a group of ducklings being menaced by an aggressive goose, prompting their mother to fly into action to protect her chicks.

The incredible display of protection saw the mother block the goose's path and even flying directly at it to attack and drive it off, never backing down against the much larger bird.

This video was filmed in May 2015.
