    Alright, I was just reading through your page about Loons and I came
    across a question titled 'Question 4'. It asked how did Loons get
    mercury into their bodies. Well here's my answer:
    Loons obtain mercury form the fish they eat. The fish get it from
    smaller orgamisms they eat etc. There is also naturaly occouring mercury
    in the water already.
