Olive Tree Runner (Plica umbra ochrocollaris)
I never did see any of these diurnal lizards during the day, but I saw a couple sleeping at night. This one was resting in plain sight about five feet off the ground. We took a few photos until it started to get nervous, then caught it and brought it back to the field station to take photos the next day. Unfortunately for me, it ended up getting released before I got any daytime photos.

Here is a complete list of the herps I saw in the wild on my 2013 MT Amazon Expeditions trip.

Olive Tree Runner (Plica umbra ochrocollaris)
This individual, of nearly identical size to the one from Madre Selva, was resting vertically and obscured by foliage. My bet is on this one for surviving to adulthood.

Olive Tree Runner (Plica umbra ochrocollaris)
This Plica umbra sleeping in plain sight from the trail on the first night of this year's trip to Peru was a good omen. I saw several more on this trip.

Olive Tree Runner (Plica umbra ochrocollaris)
This lizard, hanging upside down from a tree trunk that was leaning over a creek, was the first Plica umbra that I've seen during the day.

Olive Tree Runner (Plica umbra ochrocollaris)
On my 2016 trip I only got a couple glimpses of this species, and only this one terrible photo. I'm not even completely sure that I've identified this lizard correctly, but I couldn't come up with any other candidates.
