  • One of my favorite frogs from the Darien! The glassfrog with a super sloped snout: <i>Cochranella euknemos</i>! We were hiking through the forest one night when we passed a dried seepage. I stopped the group and quietly headed into the seepage; minutes later we heard the two note buzz of this species... We managed to collect high quality recording of this species, and photograph its cloudy egg mass. This species deposits its eggs over dried seepages in hopes that when they hatch a heavy rain will wash the tadpoles into the stream below. A risky strategy, but a great way to avoid competition for oviposition sites. <i>Cochranella euknemos</i> Darien, Panama May 2013
  • This little glassfrog (<i>Hyalinobatrachium colymbiphyllum</i>) was encountered at both sites during the most recent Panama expedition. Once the call is learned, their presence can be reliably detected without needing to have a visual of the animal. Though, finding their hiding spots on the undersides of leaves is half of the fun!
