Frog Weather

Ask any field biologist who has worked with frogs: there is such a thing as frog weather. I have been on easily over 100 night surveys in the rainforest in search of frogs and it doesn’t take long to notice a pattern emerge uniting the weather with your success in the night’s excursion.

Frogs, especially here in the rainforest, require moisture for activity and flock temporary pools/swamps of water to reproduce and lay eggs. I was last here in Tambopata during the dry season when there were very few temporary pools, so many of the frogs were hard to spot and likely hanging out up in the canopy rather than being more visible closer the dry ground. But now, it is the rainy season. Frog season.

The perfect weather scenario for frogs based upon my observations: No rain for two to three days. Then, moderate to heavy rain that day, clear weather for a couple of hours as the sun sets, and no rain to light drizzle at night. I often look at the leaves to tell me how many frogs will be out-do the leaves look dry and dusty or dewy and glistening? If it’s the latter, you have a pretty good chance of spotting a frog- or dozens of frogs- that night.

If the rain is too heavy at night, there will be few frogs visible. The males come down closer to the ground at night and call to females to reproduce- what’s the point in calling for a mate if they can’t hear you through the rain? This also helps researchers- you can identify frogs and their activity based upon the amount of calling.

So why should you go look for frogs? For one, they are quite photogenic, typically sit still, and make for great rainforest wildlife photos. Secondly, consider one of the reasons biologists go looking for them: frogs can be bioindicators. Meaning, a healthy frog population typically means a healthy environment. Many frogs breathe at least partially through their highly permeable skin, so if there are a lot of pollutants in the water the frog populations may be the first to be affected.

Also, many species of frogs are in decline due the chytrid fungus. Thus, the sad reality is that the frog extinction rate is much higher than many other animals, so you may not have long to photograph some of the more unique or rare species. Tambopata has been tested recently and no chytrid fungus was detected, so you’ll be sure to encounter some spectacular hopping frogs during your visit.

That being said, it is starting to rain here, so let’s hope for another night of frog weather. Happy frogging!

If you want to know what it is like in the jungle, this is the place to come. Amazing scenery, wildlife, and knowledgeable guides. To get the most out of the experience prepare for some early starts and early bedtimes. A fantastic few days which I won't forget in a hurry. Read all

The excursions were the best part of the trip and how the guides were so knowledgeable and welcoming. We were lucky to have seen all different kinds of animals including capybara, giant river otter, spider monkey, red howler monkey, scarlet macaw, hoatzin. Read all

It gives a great insight into the jungle. We had a great visit. I recommend going during the dry season. Our guide Luis M. was excellent! Knowledgeable, enthusiastic, kind and a gentleman. Bear in mind it's going to be hot and humid with some mosquitos. It's a jungle out there! Read all

A spectacular experience—Juan Carlos and Carmen, we’d like to sincerely thank you for our stay at your lodge on the banks of the Tambopata River. This part of our two-month trip through Peru and Bolivia left an indelible impression on us. The transfer itself was a testament to the professionalism of your team: the journey from Puerto Maldonado to the lodge—with a very tight schedule to arrive before dark, a guide waiting for us, and a smooth trip by bus and boat—went off without a hitch despite our tight flight connections. Everything about the lodge won us over: comfortable accommodations in the heart of the jungle, good food, and a comprehensive, well-structured excursion program with morning, afternoon, and evening tours. We were thrilled every time we saw something new. We’d especially like to highlight our guide, Jordi: his knowledge of the flora and fauna, combined with his patience in spotting wildlife, made our stay truly special. Equally impressive was the condition of the jungle: pristine, clean, and home to an intact ecosystem ranging from big cats to macaws. The care and responsibility devoted to maintaining this place are evident. Incredible guides. And the entire staff was very attentive. Highly recommended Read all

It was a wonderful experience and a pleasant surprise. The staff and guides at the Rainforest Expeditions lodge were fantastic and always went out of their way to ensure we had the best possible experience. Thank you to Juan Carlos and Carmen for their care and dedication to the group. Read all

We had an excellent 5 night stay at TRC with two couples. The remote Lodge and accommodation are unique especially with the open walls to the jungle in the rooms. The guides were first rate with superb knowledge and their ability to spot fauna in the dense jungle was incredible. We saw many species of monkeys; macaws, parrots, tapirs, etc.. even lucky enough to spot a jaguar. Food and service was really good. While not cheap it was I think very good value for money. We really enjoyed all the hikes and citizen science activities as well, he trips on the river and the clay licks. Overall amazing experience! As it’s the jungle not a zoo, you can’t guarantee that you’ll see everything all the time so allow enough days to properly explore. Read all

A once-in-a-lifetime experience in the middle of the rainforest. From airport pickup in Puerto Maldonado to the lodge and back, everything was exceptionally well organised. Communication was clear throughout, with the team always explaining what would happen, where to be and what to take care of. The staff at both HQ and the lodge were incredibly attentive, making the entire stay feel completely carefree. At this price point, this is the level of service you expect, but it is still impressive to experience it in such a remote setting. The food was another highlight: very well curated and balanced, with plenty of options at every buffet and, surprisingly, we never had the same dish twice. Read all

This was an excellent experience!! Highly recommend if you’re interested in visiting the Amazon Rainforest and Tambopata region. Especially happy with our guide Miguel, who was highly professional, informative, and organized. It was an immersive adventure and we got to see so many unique plants and animals. 10/10! Read all

Amazing experience at Refugio Amazonas. Rooms were comfortable and clean. Great buffet spread every day. Staff were friendly and attentive. Our guide Alan was very informative. Overall would definitely recommend a visit! Read all

We stayed 3 nights at Posada Amazonas during our summer trip to Peru, and it was definitely one of the biggest highlights of the whole journey. The staff were incredibly warm and welcoming. Our guide, Joss, was professional, friendly and amazingly knowledgeable. Sometimes it honestly felt like he could communicate with the animals — he could spot black caimans or giant river otters from hundreds of metres away! The excursions were unforgettable. We saw beautiful macaws, giant river otters, capybaras, sloths, tarantulas, an anaconda, different species of monkeys, toucans and so much more. I especially loved the rainforest walks and joined both the daytime and night walks. Every walk felt completely different, and you never knew what you might find. What also made the stay special was the lodge’s involvement in scientific and environmental projects. There was a talk every evening, and we learned a lot about the rainforest and its wildlife. We also joined the “Discover New Species” activity and helped search for possible new species of tiger moths — such a fun and memorable experience. The lodge itself is definitely rustic luxury rather than a city-style 5-star hotel. There is no air conditioning or hair dryer, but the hot shower, fan and hammock in the room were all very comfortable and suited the rainforest setting perfectly. And surprisingly, the internet connection was excellent — even the boats had Starlink! One of the things I appreciated most is that Posada Amazonas is a collaboration between Rainforest Expeditions and the local Indigenous community that owns the land. Many community members are directly involved in running the lodge, and you can really feel how much the staff care about and are connected to this rainforest, which is part of their ancestral home. If you are looking for an authentic, educational and truly memorable Amazon rainforest experience, I highly recommend Posada Amazonas. We absolutely loved our stay. Read all

The Tambopata Research Center (TRC) offers a well-organized immersive rainforest experience within the Tambopata National Reserve. The TRC and its accommodations put a spin on the term creature comforts by keeping guests comfortable while they commune among the creatures within the rainforest. I appreciated, through what I observed and the interactions I had, the attentiveness of the TRC team members. They knew their guests and seamlessly organized a lot for our benefit. The center assigns guests to a small group with a dedicated guide. In my case, Erick Arguedas was a superb ambassador for all things living in the rainforest, in part because it was the environment in which he grew up. His role was to ensure we got the most out of our visit. Being a long-term TRC guide gave him the expertise he needed to easily fulfill this role. Read all
