A Bird in the Hand…


Isn’t nearly as cool as lots of birds in the hand!  At Cuerici, our Faculty Led Project was to examine heterothermy (facultative hypothermia) in highland tropical birds.  After 3 days of mist-netting we had quite a collection of species.

In case you were wondering, we did find that 8 out of the 11 species we measured lowered their body temperatures at night, demonstrating that heterothermy is much more prevalent in high-elevation tropical bird communities than previously thought.
