Ghost Glass Frogs!

Ghost Glass Frogs!

Researchers from the Roger Tory Peterson Institute of Natural History (RTPI) have been monitoring these Ghost Glass Frogs and other amphibian species for more than two decades – not only to keep these frogs from extinction, but also to learn how the recovering populations were able to survive such catastrophic declines. Hopefully this information will help us as we try to find ways to help other endangered species as well. Stay tuned for more footage from our adventures in the...

Golden-winged Warbler

Golden-winged Warbler

Without a doubt, one of the highlights of our recent work in Costa Rica was the recapture of this Golden-winged Warbler, which was banded last year in the same area it was caught this year, near Rara Avis Rainforest Lodge. Since we last saw it in March of 2016, it undoubtedly traveled back to its breeding grounds somewhere in North America and hopefully managed to find a mate of its own species. Golden-winged Warblers are suffering from dramatic declines throughout their range, and are increasingly hybridizing with closely-related Blue-winged Warblers. As a result, this species is at serious...

Gray Four-eyed Opossum

This is a young Gray Four-eyed Opossum (Philander opossum) caught in one of our mammal traps, as we were surveying for an unusual jungle rodent called Watson’s Climbing Rat (Tylomys watsoni) in Rara Avis Nature Reserve, Costa Rica. Believe it or not, the rat would have been bigger than this opossum (and particularly fond of chocolate and soap). Like it’s cousin, the Virginia Opossum, these guys show a remarkable resistance to venoms and poisons, including snake venom, and are relatively immune to dangerous snake bites. In North America, opossums have been credited with being a biological...

Opening Eyes, Minds, and Hearts to Earth’s Biodiversity

Roger Tory Peterson traveled the world to explore, discover, and document its flora and fauna. He applied his artistic talents to describe and illustrate plants and animals in far-away regions to make their existence known to a broad audience, while his biological observations and knowledge supported conservation efforts and helped elicit positive environmental change. Like Peterson, RTPI Director Twan Leenders likewise uses his artistic skills to increase awareness and appreciation for the organisms that he studies, both locally and abroad. Leenders is currently in Costa Rica conducting...

Treasures of the Tropics

In less than two weeks an RTPI crew will be headed to Costa Rica again, this time with students from the Forman School. Students will participate in a variety of research projects, including migratory bird banding and monitoring endangered and recovering amphibian populations, such as this Rufous-eyed Brook Tree Frog (Duellmanohyla rufioculis). Stay tuned for more information...
