Geese As Guard Dogs: Security Systems Through the Ages

by | Jun 19, 2014 | Blog, Uncategorized

The desire to protect our property is not new by any means. Ancient civilizations utilized a variety of methods to keep intruders out. From the specially bred dogs of Imperial China, to the wooden lock systems of ancient Egypt, mankind has been trying to keep wannabe thieves out for centuries. We’ve gathered three examples to show just how security systems have changed through the ages.



Typically one of the last lines of defense (after a watch tower, outer wall, catapults, and more), moats were a staple of a castle’s defense system. Whether filled with water and flesh-eating creatures, or left dry and lined with spikes, moats did well to slow down attackers after the drawbridge was raised.

What happened if an intruder made it past the moat? Well, they were in for more nasty surprises. Murder holes often lined the ceiling above the passageway intruders needed to go through in order to make their way into the main grounds of the castle. Through these holes came any number of horrible things, including scalding water, tar, arrows, rocks and even boiling oil. Talk about home security!

Geese as security

Guard Geese

We’ve all heard of—and may even consider our own dogs to be—guard dogs. If an intruder is near our home, the guard dogs leaps into action with an unbroken chain of barks. We wake up and handle the situation. Or perhaps Fido goes on the attack.

But our ancestors discovered a different animal made an even better guard: geese.

For starters, these winged creatures are quite territorial. They recognize that those who live within the area they’re protecting are members of their flock. Any newcomer will cause them to sound their (alarmingly loud) honk alarm. And being able to see a much broader spectrum of color wavelengths than humans, geese’s sight is quite impressive.

Today, geese are used all over the world in tandem with modern security systems. In China’s Xinjiang Province, geese watch over the police stations at night. And guess what? It’s working like a charm.

Ancient Japan had its fair share of home invaders. As an alert system, the Japanese used an ingenious form of security: intentionally squeaky floors.Nija

Sometimes referred to as cricket floors, nightingale floors had nails inserted beneath the boards. When someone walked over the boards, the nail rubbed against the wood, causing a chirping sound. Anyone, from a run-of-the-mill intruder to a trained ninja, was at the mercy of this subtle security system.
