Why do pigeons bob their heads?
The pigeon has side mounted eyes unlike humans and owls which have forward facing eyes. As a pigeons have monocular vision rather than binocular vision they bob their heads for depth of perception. The pigeon’s eyes work much better with stationary images and therefore, as the pigeon takes a step forward the head is temporarily left behind. The next step jerks the head forward again and so on. This allows the bird to correctly orient itself.
How do pigeons navigate?
There are many theories about how pigeons manage to return ‘home’ when released 100’s of miles from their loft. A champion racing pigeon can be released 400-600 miles away from its home and still return within the day. This amazing feat does not just apply to ‘racing’ or ‘homing’ pigeons, all pigeons have the ability to return to their roost. A 10-year study carried out by Oxford University concluded that pigeons use roads and freeways to navigate, in some cases even changing direction at freeway junctions. Other theories include navigation by use of the earth’s magnetic field, visual clues such as landmarks, the sun and even infrasounds (low frequency seismic waves). Whatever the truth, this unique ability makes the pigeon a very special bird.
A great read, really interesting (and surprising).
