Migration is the regular seasonal movement, often north and south, undertaken by many species of birds. Migration is marked by its annual seasonality and movement between breeding and non-breeding areas. [16] Nonmigratory bird movements include those made in response to environmental changes including in food availability, habitat, or weather.
Before crossing the Sahara on its migration, thrush nightingales build up their fat reserves. It has been found experimentally that magnetic cues may stimulate the birds to do this. A simulation of the magnetic field found in northern Egypt encouraged birds preparing to migrate from Sweden to further build up their body fat.
The mechanism responsible for the ability to distinguish song types has not yet been fully characterized by researchers in the field of neuroethology, but it has been demonstrated that at least five different structures within the auditory pathway contain neurons that preferentially respond to conspecific song.
