A funny video has emerged of a rhea stealing feed from a four-year-old girl's bucket at a farm.

The footage, shot in Walnut Creek, Ohio on June 17, shows Braelyn giggling as a rhea, which are related to the ostrich and emu, sticks its long neck through the car window to peck at the food.

"The rheas love sticking half of their bodies inside your car. It’s actually really comical and sometimes scary because they are so aggressive when they stick their heads in the bucket of feed," her parents wrote online.

"I thought it would scare her, but to my surprise she absolutely loved it."
