Check out the webpages of Digimorph at UT Austin (under the all too aptly named "Deep Scaly Project") for some sobering craneal models and more information relating to this species.

This is the only individual of this species that Reinaldo has seen in his 20 some years of field work, and we hope that's how it will stay!

Back to the year 2002. I was pregnant with Nilo, so stayed home (at that time home was a very civilized second floor apartment in Santo Domingo de Heredia) whilst Reinaldo was in the field in Osa for 3 weeks. During that trip, whilst he was on the road for San Juan (arriba), he spotted Heliconia irrasa (a small, attractive understory forest species, which happens to be in flower currently in the LCO native plants garden and elsewhere on the peninsula). The red arrow in this image shows the position of the individual plant in question, on a steep roadside embankment ....
