Costa Rica March 12-14

I arrived in Costa Rica a couple days ago and we stayed in Alajuela for one night before traveling down to Piro Research Station on the Osa Peninsula. So far it's been a lot to take in and a lot to see, but the jungle is very cool and the food has been amazing.
Yesterday we stopped at a bridge and were told why we should never go swimming in rivers in the tropics (crocodiles). I also got a new hair stick (binyeo) that has a little iguana on it and says "Costa Rica." I've decided that since I'm so terrible with jewelery I'm going to collect hair sticks wherever I go.
We started out today with a morning birding session which included Red-lored Amazons (parrots) and Yellow-billed Caciques building their nests.
After breakfast we hiked to the beach through the jungle. We saw some cool birds, lots of buttresses, and other cool jungle stuff. Among other things, we saw a gnatcatcher in an interspecies flock which our professor was particularly excited about. On the beach we got to see some flocks of Brown Pelicans flying south along the shore. On the way back I snapped a picture of a really nice Passiflora flower.
Tonight some of us are headed down to the beach to see if we can see some turtles. We won't be back until about 1 am though, so I'll have to update tomorrow.
