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.
This little black-cheeked warbler was the first species we caught.
Sooty robins have some really cool eyes.
And a Yellow-thighed finch (a.k.a. bitey)
Just look at those yellow thighs!
Birds always look weird from head-on like this Ruddy-capped nightingale thrush
See, not so weird from profile…
A nice Sooty-capped bush tanager.
And a tuckered-out Fiery-throated hummingbird
Here he is again. Just another bird in the hand…
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.
