    Celestial navigation in animals?
    From: Bill Lionheart

    Sorry if this topic has been raised before but I wonder if anyone
    knows the latest research in to animal celestial navigation. Obviously
    plenty of examples of use of a sun compass, or moon compass, and
    polarized light on cloudy days.
    For pigeons there is this for example where they messed with the birds
    body I clocks
    Wiltschko, R, Walker M, Wiltschko W,    Sun-Compass Orientation in
    Homing Pigeons: Compensation for Different Rates of Change in
    Azimuth?, The Journal of Experimental Biology 203, 889–894 (2000)
    I was wondering how accurate animal's body clocks could  and  if any
    actually have a good sense of longtitude. Maybe not, certainly birds
    and insects tend to migrate north and south I suppose.
    ..also any other evidence of more detailed knowledge of the night sky
    in animals.
    It struck me some whales travel a long way and not just North-South,
    and they have huge brains (so could remember al lot), wonder if they
    pop up to look at the sky for navigation? Maybe they cant see so well
    in air.
    Just a thought. Sorry if it is too far off topic.
