    Default Penguin poo seen from space

    When penguins get a call of nature, they're generally not too fussy where they go.
    And as they may stay in the same area for up to eight months at a time, the ice under their feet can lose its pure white lustre by the time they move on.
    Luckily, scientists have a reason to be excited over the excrement, using the reddish-brown areas of guano (sea bird poo) to plot the movements of emperor penguin breeding colonies.


    Emperor penguins, among the largest in the world, are hard to track during Antarctica's harsh winters - but now scientists can now track by satellite
    The 'reddish-brown' spot helped to identify the colony of penguins

    Experts used satellite images to survey sea ice around 90per cent of Antarctica's coast, and were able to identify a total of 38 colonies, including 10 that were new, by looking for the tell-tale patches.
    Of the previously known colonies, six had re-located and six were not found.
    Experts need to track the movements of emperor penguins to monitor their response to climate change.
    Mapping expert Peter Fretwell, from the British Antarctic Survey (BAS), said: 'We can't see actual penguins on the satellite maps because the resolution isn't good enough.
    'But during the breeding season the birds stay at a colony for eight months. The ice gets pretty dirty and it's the guano stains that we can see.'

    Emperor penguins, identifiable by gold patches around their ears and chest, spend a large part of their lives at sea.

    During the Antarctic winter when temperatures drop to minus 50C they return to their colonies to breed on sea-ice, but this is the time they are most difficult to monitor.
    BAS penguin ecologist Dr Phil Trathan said: 'This is a very exciting development. Now we know exactly where the penguins are, the next step will be to count each colony so we can get a much better picture of population size.
    Using satellite images combined with counts of penguin numbers puts us in a much better position to monitor future population changes over time.'
    This research, reported in the journal Global Ecology and Biogeography, builds on work by French scientists who extensively studied one penguin colony and found the population was at significant risk from climate change.
    The six colonies not found in the new study were at a similar latitude, suggesting emperor penguins may be at risk around the whole of Antarctica.

    LOL, they you woud love my friend! She's loves penguins and they are all over her house. She started collected penguin stuff and then everyone she knows started buying penguin stuff for her so now it's overwhelming. It's cute though, I wish I had a favorite animal so I could collect stuff.

    lol i love them but i don't collect any animal stuff. unless you count my smoking rabbits.
    i recently saw penguins in their natural habitat for the first time. i'd seen them before at the zoo but it's another thing altogether to see them in their natural habitat. i was jumping up and down like an idiot. sea lions too. they're so fucking adorable it hurts.

    That's really cute! I would be excited too. It's cool you got to experience that, hope you took some pictures!
