Peruvian Amazon January 2013 Part 1, Amphibians

Post by Matt Cage »

Hello
In January, I was a trip leader for MT Amazon Expeditions (formerly Margarita Tours) herp photography trip to the Peruvian Amazon. Their website is here: http://www.amazon-ecotours.com and it’s in the process of being updated.

We took a great group down, meeting in Iquitos. Iquitos is a town of half a million people, but only way in or out is to fly, boat or walk. No roads going in. Spending a day or two in town is part of the experience. Here are some photos of around Iquitos.

There are herp activities that can be done around Iquitos. There are some preserves just out of town, and you can view wild herps at the Iquitos Zoo. Sometimes we rent a car and go road cruising on the one road that leads out of town to a nearby town. That can be productive.

On the trip, we found a total of 122 species of herps. Plus, lots of other stuff. Kayaking with the pink river dolphins is an incredible experience.

We spent 7 days at the Madre Selva preserve and and 4 at Santa Cruz. In route there and in between, we spent a lot of time on boats. Here is some transportation photos:

The first stop is Madre Selva. It takes all day by house boat or 3-4 hours by speedboat to get there from Iquitos. It is downstream on the Amazon, on the Rio Orosa. It is a beautiful preserve and there is some incredible wildlife viewing. There is a canopy level tower which gave daily opportunities for view birds and monkeys. I have been to Madre Selva many, many times, and each time I go, I have an incredible time. Here is some views from around the Madre Selva facilities.

The classroom is now 2 stories!

This is the floating boathouse. Some years, when the water is low, the boathouse is a ways away from the facilities.
Image

This is my 4th trip to Santa Cruz. Santa Cruz is a newer preserve and some of the facilities are a bit more primitive. It is worth going there, as the herping is different than Madre Selva. Though closer to Iquitos, Santa Cruz is very wild. There are two places to stay, a house along the river and some tambos and a house up the hill a mile and a half away. Here is some of the photos around the facilities, including a new pond that is very near the top lodge area.

On to the herps. I’m going to start with the amphibians. We were in the height of the rainy season and the Amazon was very high. It was as high as I have seen it, though nowhere near where it crested in February of 2012. It rained most days and the small streams were all flowing and active with wildlife. These critters were found by participants, guides, or by locals that sometimes bring stuff in.
Image
Typhlonectes compressicauda
Common Aquatic Caecilian






Salamanders are not commonly found in the Amazon Basin. Personally, I usually find 1 or 2 per trip on leaves at night. As a group of experienced herpers, we found 4 this trip.
Image

Image
Bolitoglossa altamazonica
Amazon Climbing Salamander





I have never found these to be very common. They are huge and quite impressive.
Image
Image
Rhaebo guttatus
Smooth Sided Toad






These toads are extremely variable in colors.
Image
Image
Rhinella dapsilis
Sharp Nosed Toad






One of my favorite toads. Some specimens are simply spectacular. They are also fairly common, though most do not have the full crests and ridge.
Image
Image
Image
Image
Rhinella margaritifera
Crested Forest Toad






And the ever common Cane Toad. Always nice to find them where they are supposed to be.
Image
Rhinella marina
Cane Toad







These are one of the treats of going to the Amazon. There is still a stable population of these down there, if you know where to look.
Image
Image
Image
Atelopus spumarius
Amazon Harlequin Toad







On to the treefrogs:

Dendropsophus haraldschultzi
Many Striped Treefrog






Image
Dendropsophus marmoratus
Marbled Neotropical Treefrog






The always spectacular Clown Treefrogs
Image
Image
Dendropsophus leucophyllatus
Clown Treefrog







Finding these in abundance is always in incredible experience. We find normal phase, and all sorts of different phases. I spend hours looking at them!

Image
Image

Flat Headed Bromeliad Treefrog







Image
Osteocephalus taurinus
Giant Broad Headed Treefrog







Image
Phrynohyas venulosa
Common Milk Frog







The Phyllomedusa species are simply OUTSTANDING. When I first started going to the Amazon, I would be lucky to find them. I usually came across and individual here or there of one or two or two species a trip. It was always a great find. Well, now, at Santa Cruz, the habitat must be very good for them. They show up all the time. Walking around near the facilities and a nearby pond at night will usually get you 3 species, and sometimes lots of each of them. We started naming them this year as we would see the same ones night after night.

I believe this to be Bob (Mike can you confirm?)

Your pics are fantastic, you're a great photographer to be sure. The rest of your pic are likely just as amazing. I love seeing the Rhinella and Glass Frogs. So many others I haven't seen before. I'm glad you posted I haven't seen Mike's pics as I'm not on Facebook, but have been hearing about them. He's been busy he said and will post as soon as he finds time. Looks like you guys had a great group, I can't wait to get down there some day.

Matt,

Great set of amphibian photos. The frog diversity is so incredible at those field stations. I saw a number of familiar species but also a number that we missed a couple of years ago. I really liked the pattern and colours of Dendropsophus marmoratus ... great looking tree frog.

Have you been there on a June trip? How do those compare? I think that it must be drier at that time of year so maybe not as good for frogs but better for butterflies.

I am looking forward to the next posts!


Regards,
David

I have to chime in as I was on this trip (I'm the sexy bald guy). It was an amazing time. There were so many species you can get burned out. I have to encourage you all to consider trying this tour. I'm not a tour person (I like going off on my own), but the quality of herpers on this trip was off the chart. If Dick Bartlett isn't there to help out, I turn one way and Matt Cage is there or I turn to the others side and Mike Pingleton is there, or Jake Scott (those just a few I know to be on this forum). Killer time. I know why they have so many repeats. I want to go back already.

I've heard of Margarita Tours, and I didn't need a lot of selling, but consider me sold. As soon as my kids are old enough that I can dump them on my wife for a few weeks, I'm there!

Is the Rhinella margaritifera a mimic of Corytophanes or some other crested lizard, or is it convergence, or just coincidence that it looks so lizardlike?

Thanks to everybody for the replies! I'm hoping to find time to get part II up in the next day or two. Hopefully more participants will post soon.

Justin, hopefully Mike will post soon, he has some GREAT shots. We did have a great group of people.

Jake, it was great spending some time with you. We laughed, we cried, we scratched out bug bites! Thanks so much for coming!

Reptilist / Justin/ Dave/ Pete /RiR / Rags/ Zach/ Matt/ Michael/ Antonsrkn, thanks so much for the comments!

David, that marmoratus was quite incredible. It was a patchwork of colors. I have been in June and had a great time. There seemed to be an overall little bit less rain, it seemed slightly cooler at night, there was less amphibians seen, but the lizards and snakes seem to move just fine. The species found may be different from the January trip. Also, when I have been there in June, the water was much lower, but the small creeks were flowing and it still rained almost everyday. It would be a slightly different experience. I really hope to see you there soon (or anywhere for that matter). I did take a few butterfly shots for you, they are on my website. Thanks a lot for the words!


Jim, I have to say that it was great meeting you and getting to spend some time with you. I really hope you had a good experience. I'm not a "tour person" either, but this is really a self paced site. Once you learn your way around, you can go out by yourself or with anybody else going for a walk. You are welcome back anytime and remember, there are returning passenger rates! Sorry to cause you to join facebook to see the photos!! Hope to see some of your photos posted soon!

Cbernz, if you have any questions about the tour, please let me know. I'm not sure if the margaritifera are mimics of lizards or not. Hopefully somebody will advise what they think. Only about 10% of the adults that you find have the large crests and some have no crests. I'm guessing that it just makes them look bigger. They are spectacular. Thanks for the comments!

Matt, I'm glad you posted this -- I was half-planning to do a big Peru post but haven't gotten around to it. Not to continue to be as picky as always but I think your Hypsiboas lanciformis photo is really an Osteocephalus. We did see several Hypsiboas lanciformis but I think the snout on that frog is too rounded to be that species.

Everyone -- it really was an incredible trip. And I can vouch that Matt really is as nice a guy as you would guess from reading his posts.

This is great, Matt. I think you could make a full post out of the Hyla leucophyllata/sarayacuensis/triangulum/bifurca group alone. There's no experience quite like seeing these tiny choristers vocalizing from their spots on the floating vegetation. dick
