Pigeons with a deficient sun compass use the magnetic compass



Pigeons with a deficient sun compass use the magnetic compass



Science 214(4518): 343-345



Homing pigeons that had never seen in the sun before noon could not use the sun compass in the morning; nevertheless they were homeward oriented. When such birds carried magnets they were disoriented, suggesting they were using a magnetic compass. Apparently the magnetic compass is available to pigeons whether or not the sun compass has been established, and the magnetic compass is apparently the 1st source of compass information.
