D.A. Good 1987 Journal Ulcán Cacao, Prov. Guanacaste, Costa Rica 31 August down the roots came out of the bank, I fell into the streambed with the tree on top of me and CF, who happened to be standing exactly opposite looking at the frog I had given him got clouted on the head by the tree. While recovering from this mishap we heard another Centrolenella on the same bank + managed to reach the small sapling it was in with a potato stake. I pulled the whole sapling out of the ground+ down the bank far enough to reach the frog. Also collected along stream was a baby Bottineps lateralis. Return to Casa Mengo ca. 1000 PM. At approx. the summit of the trail (1270 m elev.), (F, who was walking in front along the trail saw a cat on the trail ahead, ca. 10 m away. A margay. It looked at us for a while and, obviously not recognizing us until our headlights on its eyes as people, it came closer. And closer. And closer. Eventually, when it was ca. 1½ m away (i.e., almost standing on CF’s feet), I said “what should we do?” The Margay then ran off about 2 meters + sat + watched us some more. Eventually it walked off the trail + disappeared downhill. 1-5 Sept: Ulcán Cacao to San José, Costa Rica Notes written 6 September. Not much worthy of writing notes on for the last few days (this in part being an excuse for laziness on my part). Spent 1 September packing up our equipment for leaving Casa Mengo — did no collecting that day. On 2 Sept. we left Casa Mengo
