Predation attempt and abnormal coat coloration of the tayra (Eira barbara) in the Brazilian Central Amazon

Predation is one of the most important interactions between species and a major selection pressure in wild mammal populations. Camouflage is a common pattern of colorations resulting from predation pressure, however, atypical coloration may appear in the wild. Both predation and atypical coloration in mammal species are difficult to observe in a natural setting but contain important biological information. Here we describe a leucistic tayra (Eira barbara) attempting to prey on a sloth (Bradypus tridactylus). The event occurred in Brazilian Central Amazon as a tayra unsuccessfully tried to kill an adult sloth in the mid-canopy of a secondary forest.
