Caterpillar-like baby hummingbird
Potential caterpillar mimicry in White-necked Jacobin chicks discovered in Panama.
March 18, 2025
A baby hummingbird hatches. But it has fluffy feathers on its back, looking just like a dangerous caterpillar. Could this be something unusual among hummingbirds?
Living Small in a Big City
Túngara frog tadpoles that grew up in the city developed faster but ended up being smaller.
June 30, 2025
Have you ever wondered how city life affects animals like frogs? A new study reveals that urban Túngara frog tadpoles develop faster —but end up being smaller — than tadpoles from forests, probably resulting in smaller adults. This might be an adaptation to warmer urban puddles with fewer predators or to constantly changing environmental conditions in the city.
How do bats handle unnatural noise?
Frog-hunting bats overcome noisy environments by switching sensory channels
September 15, 2016
A discovery by a Smithsonian intern in Panama is published by the journal Science.
Scientist
David Roubik
I’ve gotten used to performing long-term studies, and shorter-term field experiments, but most of all try to mix and match what is both interesting and useful. Many studies have come to fruition, and those I continue to expand consider 1) ecology and taxonomy of stingless bees and orchid bees, 2...
Maya Dog Mystery
First Evidence of Live-traded Dogs for Maya Ceremonies
March 21, 2018
At one of the oldest Maya sites, STRI staff archaeologist, Ashley Sharpe, discovered dog bones from the Guatemalan highlands deep within two pyramids.
Learning from other species
Predators learn to identify prey from other predators
March 21, 2018
It is much faster to learn to recognize a new prey item from a neighboring species, than to learn by trial and error.

Lessons From Amphibian Die-off in Panama
March 30, 2018
What slows or stops a disease epidemic if the pathogen is still present? It appears that wild frogs are becoming increasingly resistant to the chytrid fungal disease that has decimated amphibian populations around the world.
