A leshy can mimic the calls and voices of any creature it has heard. To use this ability, the leshy makes a Charisma (Deception) check. Listeners who succeed on an opposed Wisdom (Insight) or Intelligence (Nature)-GM's choice-realize that something is mimicking the sound. The leshy has advantage on the check if it's mimicking a general type of creature (a crow's call, a bear's roar) and not a specific individual's voice.
