Rio San Pedrillo

Today, Mike and I leave San Jose for Cleveland. We successfully trekked Peninsula de Osa and collected some solid data for Mike’s dissertation at 14 beautiful, tropical streams, the first of which, Rio San Pedrillo, is pictured below.  A great start to a great trip.

On the road to Volcan Irazu sits a small restaurant with several pictures of well dressed men… plus some guy in a truckers hat.

This is what likely stings us while in the ocean in front of Campanario, according to Helena Molina.  In that part of the Pacific coast of Costa Rica, they don’t get much larger than this (about the size of a silver dollar), so they aren’t very dangerous.  They still hurt…

A caterpillar

I first though this glob on the underside of a leaf was an egg mass from a frog, maybe a centrolenid.  I took a picture, and it appears that there is a caterpillar in the center.  Is it alive?

A Leptodactylidae

I didn’t have a chance to key this frog out using Savage, but my best guess is Pristimantis (formally Eleutherodactylus) caryophyllaceus.  We encounter it at San Ramon. 

We also encountered and keyed a tadpole from Duellmanohyla rufioculis, a beautiful red-eyed hylid.

Right, Mark?

This little bird was caught at Campanario and died as we attempted to release it from the mist net.  Only two other bird species were caught in the mist net: Black-cheeked ant-tanagers and tawny-backed woodcreepers.
