# Pigeons Are GPS Drones

## Summary

The video explains how pigeons, bred by humans for their homing ability, served as a wireless communication network in history. It details their navigation methods: using smells to build a map, checking the sun's position with their internal clock, and sensing Earth's magnetic field through electric currents in their inner ears. The video concludes that modern city pigeons are descendants of this living network.

### Key Points

- **Pigeons as a communication network** [00:03] — Pigeons were selectively bred by humans to enhance their natural homing ability, turning them into a wireless communication network.
- **Navigation methods** [00:15] — Pigeons navigate using a map of sights and smells, cross-checking the sun's position with their internal clock, and sensing Earth's magnetic field through electric currents in their inner ears.
- **Legacy** [01:04] — Modern city pigeons are descendants of this historical living network.

## Transcript

hundreds of kilometers from their roost and navigate home autonomously. Humans selectively bred them to supercharge this natural homing ability until they functioned as a wireless communication
network. They announced the winner of the Olympic Games and carried life-saving messages in war zones. But how do they do it? [music] Pigeons build up a map of their environment from sights and especially smells. They begin
to learn wind-borne odors around their lofts as checks, so even if they're blown off course, they can still sniff their way home. Cross-checking the sun's position with their internal clock gives them an onboard compass. But that's not
their only trick. As a pigeon travels through Earth's magnetic field, the motion induces electric currents in fluid-filled loops in their inner ears. Proteins sensitive enough to detect the signals can give them coordinates and
directional cues similar to how sharks sense their prey. Though we slowly replaced pigeons with wires, they didn't disappear. The birds cleaning up crumbs in cities today are descendants of a living network whose story is
living network whose story is inseparable from our own.
