Decidueye is a Grass/Ghost-type Pokémon of the seventh generation.
It evolves from Rowlet at level 17 and then from Dartrix at level 34.
Decidueye is a tall, avian Pokémon that resembles an owl. The upper portion of its face is dark green with a thin, orange mask-like marking encircling its eyes. Its eyes are reddish-orange and it has a hooked dark green beak. The feathers covering its wings and back are brown, while its body is primarily white. The three feathers at the tip of each wing are structured similar to fingers and have lighter tips. The backs of its wings and torso are dotted with many white spots, there are six on each wing. The inside of each wing has a line of upside-down, reddish-orange triangles across the top. It has long legs, feet with two toes facing forward and two backward, and short dark green talons. Its tail consists of three long, green leaves.
A leafy hood covers its head and shoulders, and partially covers its face. The hood is smoothly draped across the shoulders and back, but has uneven edges. Around the head, the hood forms many pointed projections that extend over its face. A single white feather with a red base extends from the top of its hood. In the center of its chest is a reddish-orange x-shaped formed by dead leaves with two thin green vines extending from it. Pulling on the vines closes the hood further over Decidueye's face and improves its focus.
