Giant Gladiator Treefrog - head closeup, Uraba, Colombia After navigating the Cotton-top Tamarin for only 2 or 3 hours, we made a retreat. It&#039;s an absolutely gorgeous forest but our pace was too slow due to the conditions. It would have taken us another 6 hours of uphill deep mud where each step sucks you in 20 inches, in order to reach grounds where some birding was possible.<br />
<br />
A pity, I&#039;d gladly spent weeks navigating this forest, but we only had one daytime block assigned to this park, so it was the right thing to try to find a more productive use of our day. Retreating back to the park ranger&#039;s hut, we found this absolutely huge treefrog there.<br />
<br />
It&#039;s known as the Rusty Frog, but I prefer the cooler Giant Gladiator Treefrog name. Even to our local guide Carlos, an absolute herping fanatic, it was the first time he saw it in his life. Indeed, the range within Colombia is described as only occurring in the Amazon and Colombian lowlands, so it&#039;s not expected here.<br />

  1. Gorgeous. Again, another frog with absolutely incredible eyes. Amphibian eyes would make an awesome abstract collage...But, the mud - that’s crazy. Must have been exhausting to attempt to traverse that. Posted 7 years ago
    1. The mud was both fun and exhausting. I generally don't mind a little hardship like that. In fact, it kind of excites me, as usually it means you're going to an interesting place :)

      So it was not really an effort issue in this case, it was a time issue. This was another part of Uraba (we moved hotel for one day) where we had a single day to explore, and we couldn't use all daylight just to hike.

      Quite a pity, as it's one of the most incredible forests I've ever set foot in. I could spent weeks exploring just that park.

      1. Maybe you'll get back there next time! I agree that the most arduous places to get to are often the most worthwhile, and it's so much fun to muck through to the end :)
