Homing pigeon
The homing pigeon is a variety of domesticated dove that has been selectively bred to be able to find their way home over extremely long distances. Because any pigeon generally returns to its own nest and its own mate, it was relatively easy to selectively breed the birds that found their ways home over repeated long flights. The birds carry messages (frequently written on cigarette paper) in small tubes that are attached to one leg. Flights at least as long as 1689 miles have been made by exceptional birds in a pigeon racing competition. Their average flying speed over moderate distances is around 30 miles per hour, and they can achieve bursts of speed up to 60 mph.
These birds should be distinguished from carrier pigeons, another breed entirely.
