The Smithsonian has maintained the island with as a scientific research facility since that time, and the flora and fauna there are among the most studied anywhere in the world. Hundreds of scientists conduct research projects on Barro Colorado Island every year.
The biodiversity of the island is incredible. They marked off a square mile at the top of the island and catalogued every tree over an inch in diameter. They remeasure every tree at five year intervals. It turns out that there are more species of trees in that square mile than in all of North America!

Our guide Irisol spoke good English and explained the sights along the trail.
Irisol pointed this flower out to us and told us it was called "Clitoria"
She even pulled out her guidebook to prove she wasn't making it up!
This little lizard was getting some sun |
No, this is not a green snake! It's a vine wrapped around the tree.

We came upon a group of howler monkeys, the same kind that we used to hear in Chepo. When they first heard us, they howled very loudly, and even tossed a few nuts in our general direction. After a few minutes, though, they calmed down and went back to eating leaves and playing in the trees. This was the best look we had gotten at howler monkeys in all of our time in Panama.

This is called a "Monkey Condom", though we suspect it has other uses. Of course we had to return it to the exact spot where we had found it.
After lunch, we stopped by the BCI museum. These croc heads caught our eye. Up until the end of 1999, the US controlled the Canal Zone, and they allowed crocodile hunting. Since then, however, hunting is prohibited, which means there are a lot more crocs than there used to be. There have been cases of people fishing from the banks of the canal being attacked by crocodiles. Evidently they are really good at sneaking up on their prey, human or otherwise!
During our first few months in Panama we were in our training community not far from Lake Gatún. We did go swimming in the lake a couple of times but didn't see any crocs!
We met a couple of scientists from Dartmouth who were studying katydids, which look like small grasshoppers. There are 145 species of katydids on the island! Katydids communicate using ultrasound, as do bats (only 74 species of bats on the island), and these scientists were testing to see if bats would hear the katydids and come to eat them, and also to see if the katydids could hear the bats and take cover to protect themselves. In any case they said they were going to protect the katydids with netting so they wouldn't get eaten. So thoughtful of them!
With that, we returned to the boat, leaving BCI behind. The next day we would fly home to the US. We had such a great time in Panama that we are already thinking about when our next visit should be!
We'll keep you posted here!
