The third species of Porthidium I’ve encounter, P. porrasi is found on the Osa Peninsula. I discovered P. nasutum in La Selva a few years ago, and P. ophryomegas in Palo Verde last June. I’ve yet to see P. volcanicum though…

Finally
First time sighting one of the classic frogs of Costa Rica: the red-eyed leaf frog, Agalychnis callidryas. Absolutely beautiful.

This little anole seems to the the most common around the Proyecto Campanario, on the Osa Peninsula. Their patterning and colors vary on their body, but the dew-lap is mostly orange.
Diasporus defends territory

My best guess for these dwellers is Diasporus diastema in the family Eleutherodactylidae. It was formally Eleutherodactylus diastema in Leptodactylidae… so maybe it’s a new family sighting for me!
Norops capito

A new anole for me… but Oscar caught it.
Yellow-headed gecko
Hello Thamnophis
There were several ribbon snakes (Thamnophis proximus) around to greet us upon arrival in the wetland. They are fairly aggressive and difficult to catch because they quickly slide underneath the vegetation.
Boa constrictor
A juvenile boa caught at Palo Verde that I would have loved to take home…
Unknown Leptodactylid
My herp count did not include amphibians or reptiles that I wasn’t completely certain on their identification (or at least, fairly certain), like this Leptodactylid (rain frog). It’s certainly a different species from those that were included in the count, but I can’t provide a definite identification, and therefore I cannot enter it in my herp database.
The perch this frog is using in a small leaf’s petiole, just to give some scale.
