Geophagy involves the consumption of soil to supplement diets and to facilitate digestive processes. We used camera traps to document the use of a salt lick by Linnaeus's two-toed sloth Choloepus didactylus (Linnaeus, 1758) from December 2014 to November 2015 in a lowland Ecuadorian forest. We obtained 201 videos of sloths and analyzed if rain or lunar-phase influenced these visits. Visits were positively correlated with monthly rainfall and negatively correlated with lunar illumination, but correlations were not significant. We consider three hypotheses for visiting licks: (a) to supplement their diet, (b) to help digestion, and (c) to obtain water.
