The sensitivity of the pigeons to those bodily properties permits them to find out their directional heading and altitude by utilizing Earth’s magnetic area. The identification of the bodily construction throughout the pigeon’s physique that collects this magnetic area info and sends it to the mind stays unknown, however, some scientists suspect that it could lie throughout the interior ear.
