Jan 17 high up in same tree that Fedor climbed and got 9 B. engelhardtii; released 3 girls. Continued up path; around 2000m, the trees began to get shorter and bromeliads became scarce. The trail was extremely steep and seemed to follow a ridge. We got 2 more B. engelhardtii out of 13 bromeliads, including a huge adult that I found in an isolated bromeliad. We spent almost no time looking under logs, as the forest was completely dry and there wasn't any moisture under or even inside most logs. The forest continued to get scrublier and shorter; Fedor told me that this area had burned ~10 years ago. Around 2500m, we began to see some pine trees. I opened a medium-sized bromeliad and got a small black Bolitoglossa that I don't think is B. engelhardtii (although it could be); yet less well fed and coloration is totally different. We opened 10 more bromeliads here and got 2 more subadult Bolitoglossa, at least one of which looks like B. engelhardtii. Carlos + Fedor saw 2 horned guans while I was opening bromeliads. We continued up to 2675m elev., where we opened ~4 more bromeliads, but the habitat seemed very disturbed, although Fedor said we were getting toward the upper edge of the forest, so it may have been like this naturally. More pine trees + bamboo here. Turned back at 17:25; saw a male horned guan at same place where they had seen a pair. Nealization sounds like clicks followed by a warbling sound. Caught up w/ Fed, who had turned back at 2500m, and walked to the bottom, arriving at 19:30. Saw a Patas flavaus and several Bassariscus on the way down. The day was hot, perhaps around 35°C; clear in the morning + evening but cloudy in the afternoon.
