Counting at distance

  • ioana_bilea by ioana_bilea

    Up to which distance is it scientifically ok to count? some penguins are really far,they could be easily mistaken for rocks,or rocks for penguins. In this case the result could have a lot of errors

    @ioana_bilea - Straight from our FAQs for your use:

    "4] Tiny / distant penguins / other birds

    If there are more animals on a distant hill who look very small and are probably penguins but they're too small to be marked, don't mark them. When you finish the classification, please, click on the 'Too many to count' button.
    If the image shows only distant penguins too small to mark accurately, please mark just one (or "at least one") before choosing the "Too many to count" option.
    Much more here: Please read the FAQs, everyone!

    Hello ioana and thank you for asking about distant penguins

    You should never mark something unless you are sure it is a penguin. So the very distant penguins you might never mark at all.

    Sometimes you can see that they are penguins, but they are too close to each other on the picture that you cannot mark them all so then it helps if you simply mark at least one of them. Whether you can mark one or not, please finish with 'too many to mark'.

    Over the last three seasons of PenguinWatch the scientists have assessed our marking, and the rules we use give a response which provides them with the information they need. It may help you to know that each picture is marked by about 10 people.

    We have some good advice on marking difficult pictures here: https://talk.penguinwatch.org/#/boards/BPZ0000007/discussions/DPZ0000aay

    Thank you for counting penguins 😄
