Lower falls
I’ve probably already posted this shot somewhere, but I like this place.
Rio Camarones Oraganic Matter input
I study decomposition in aquatic systems, and most research in this area focuses on leaves as the major source of outside input of organic matter into these systems. However, in tropical systems, flower and fruit material can make up a substantial portion of OM input in streams, as discuss in Tropical Steam Ecology and evidenced in this photograph.
While sampling, flower parts rained into Rio Camarones in Sirena, completely covering the surface. And, just like in Ohio, the stream was filled with abundant crustaceans, probably acting as shredders!

Black-throated Trogon
Both a male and female Black-throated Trogon perch quietly at the forest-beach ecotone.

Sirena Sunset
Sirena Canoe Trip
| Probably the best day in Osa was when we sampled two streams feeding Rio Sirena and traveled to the streams via this boat. We saw a tapir, we caught snapper, we saw squirrel monkeys, a bat falcon taking a Costa Rican Swallow, bull sharks, and American crocodiles – and, of course, successfully sampled two streams. |  |
Fishing hole
Brian caught two large snapper for dinner on our return trip from the canoe up Rio Sirena. Hundreds of fish swam about in the clear water river. If you’re an avid fisherman, use freshwater shrimp if you want to make catches like this.
