Darwin’s Frogs in the Field / Ranas de Darwin en el Campo

January 14, 20103 Comments

Our team has been busy working in the field.  Among our objectives, we want to visit historical localities for Darwin’s Frogs and determine if they are still there.  If we find frogs, we take skin swabs and see if amphibian chytrid fungus is present.

      Hi Jim,

      We raise our baby frogs individually in small containers. We do this to make sure that each individual gets an appropriate amount of food. As the frogs get older, we begin to accommodate them in small groups. Our newly “born” frogs eat small invertebrates called collembola and aphids.

      Cheers & Thanks!!

    My son recently found a small frog that I think might be a Darwin frog though he’s not green. Is there a way I could get a picture of it to you all to find out.
    Thanks!
