Why Birds Don't Fart

Publish date: 2024-05-02

To understand why birds don't fart, you have to understand a little about why any creature farts. Technically known as flatulence, farts are simply the expulsion of gas from the digestive system through the southern route, as it were. (Sometimes it's referred to as "a back-door burp.") Gas collects in the body as the result of breaking down food, or swallowing air via eating or drinking, according to Healthline.

Birds have shorter digestive tracts than many mammals, including humans, and that gives them the ability to digest food much faster, according to BirdFact. In fact, they digest food so quickly that some birds poop every 5 to 15 minutes. The speedy process from ingestion to exit essentially prevents the formation of gas. Birds also don't have the same type of bacteria in their digestive systems that humans and other animals do. It's that bacteria that aids in gas formation, according to Popular Science.
