Currently, it is generally assumed that migratory birds are oriented in the appropriate migratory direction under UV, blue and green light (short-wavelength) and are unable to use their magnetic compass in total darkness and under yellow and red light (long-wavelength). However, it has also been suggested that the magnetic compass has two sensitivi...

У птиц, мигрирующих ночью, функционируют звёздный и магнитный компасы. Звёздный компас птиц не является врождённым, поэтому, чтобы иметь возможность им пользоваться, молодые птицы должны научиться распознавать центр небесного вращения — Полярную звезду, указывающую на географический север в Северном полушарии. Предполагают, что чувствительный перио...

Previously it has been shown that migratory birds were oriented in the appropriate migratory direction under UV, blue and green monochromatic lights (short-wavelength) and were unable to use their magnetic compass in total darkness and under yellow and red lights (long-wavelength). Currently, it is generally assumed that the magnetic compass of bir...

The star compass of birds, as well as the sun compass, is not innate. To possess either of them, the birds have to observe the rotating sky and determine its' center of rotation (in the star compass case) or the sun's movement (in the sun compass). Young birds are believed to learn how to use the star compass before their first migration, even thou...
