Bothrops atrox - side view, La Isla Escondida, Colombia
What a day it was. Birds, frogs, endless moths and insects, a velvet worm and then another awesome break from mothing when our guide Manuel found this Fer-de-lance. It is considered the most dangerous viper of Colombia and surrounding countries for being both highly venomous and somewhat likely to live near human settlements.
This is likely a juvenile, as it was really small. It was found on a log and just sat there, it made no defensive or offensive moves at all. It was in the exact same position the morning after. I really wanted a tongue out shot, so waited for that.

"Bothrops atrox" — also known as the common lancehead, "fer-de-lance", "barba amarilla" and "mapepire balsain" — is a highly venomous pit viper species found in the tropical lowlands of northern South America east of the Andes. No subspecies are currently recognized.
