Bicolored Antbird

Bicolored Antbird

Here’s a catch made during my recent research trip to Costa Rica. Not a neotropical migrant this time, but a local resident species. This unusual-looking fellow is a Bicolored Antbird (Gymnopithys leucaspis), one of several so-called “ant-birds” that are usually found only in the vicinity of army ant swarms. All day long these birds follow the ants -at a safe distance- and expertly capture insects that are flushed, but not caught, by the invading...

RTPI in the Rainforest – Conservation, Education and Inspiration

RTPI provides innovative programs that bring nature back into people’s lives. RTPI researchers work with school and college students to give them a chance to study natural history first-hand, and open their eyes and minds to the workings of the natural world. Whether in our own backyard, or in a remote corner of Costa Rica, RTPI works to increase understanding of the natural connections between species, habitats, and people that are critical to effective conservation. Learn more in this outstanding video created by Nicholas Gunner of...

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

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...
