Breakfast, Las Alturas, New Year's Day 2018.
The bird team got off to an early start, netting and measuring birds.
Measuring bill width. Back in BIO-101, the students had learned about Peter and Rosemary Grant's famous study of the evolution of bill size and shape in Galapagos finches. Now they are making the same measurements themselves.
While Jonathan and Ashely measure the bird, Caroline works to identify it.
A white-ruffed manakin. Male manakins, under sexual selection, are much more colorful than females.
A purple-throated mountin gem.
Meanwhile, the butterfly team captured a blue morpho.
A view of the ventral surface of the wings of the same morpho, just before it was released.
That afternoon we hiked down the road from the bunkhouse. Las Alturas, in addition to protected primary forest, has working pastures for cattle and horses.
We picked some oranges along the road, of the original sour type used in cooking. (Sweet oranges are a recent innovation.)
An epiphytic bromeliad, in flower.
A . parrot, high in a tree. Enlarged at upper right.
A view of the vast Amistad National Park, shared by Costa Rica and Panama. (Amistad translates as "friendship.")
Amistad National Park.The blue flowering plants in the foreground look very much like purple mist flower (a species in the mint family) back home.
A view of the cloud forest (enshrouded in clouds) atop the mountain that we climbed yesterday. Yesterday we were up in those clouds!
Returning to the bunkhouse at Las Alturas.
The final night at each biological station is celebrated with a quiz on animal and plant ID. This New Year's Day quiz focused on arthropods and birds.
At lerast one student enjoyed it.
