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.

Living quarters
 |
 |
| We stayed at what I think is the old Sirena station for a few days. The roof and bed pads were great luxury, but the mice created a bit of stress. The station was set back a bit from the new station, which was filled with tourist coming in and out. The three of us were on our own for most of our stay, but another researcher, whom we had incidentally met in Palo Verde, shared the station the last couple of nights. |  |
White-eyes
| Ojos Blancos (Oxyzygonectes dovii – Family Anablepidae) look a bit like gigantic mollies. We discovered and caught some as the tide raised Rio Sirena. |  |
Tons of spiders
| A nest of recently hatched spiderlings disperesed from a small, stream-side plant in Rio Camarone, Sirena. |  |

Orb weaver wraps up a fly
While sampling Rio Camarone near the Sirena field station, I wandered upstream and noticed an orb weaver’s web. As I moved passed it, I bumped a leaf with a perched fly and the fly flew right into the spider’s web. Thus, it’s psuedo-unnatural, but from the look of the third picture, similar prey items are usually encountered by this spider species anyway. I had seen a number of flies from this family perched on leaves adjacent to streams many times in the past, and I hope one that I’ve collected for Dr. Foote will provide an identification.

Foraging Brown Pelicans

On the hike back from Rio Claro, Helena and I stopped to watch several Brown Pelicans feed on fish as the waves crashed into a small cove.
