Noctowl, the Owl Pokémon. The evolved form of Hoothoot. This highly intelligent Pokémon often twists its head 180 degrees when it is thinking. Noctowl is a nocturnal Pokémon.
– Ash’s Pokedex
Noctowl is Gen II’s normal bird. It’s a two-stage evolution, evoluting from Hoothoot at level 20.
In the anime, Ash had a shiny Noctowl. It’s Ash’s only shiny Pokemon. It’s also different from Ash’s other Normal birds because he caught it as a Noctowl instead of evolving into it like his other normal birds.
Stat-wise, it has high HP, good Sp Defense, and unlike the other normal birds, it has higher Sp Attack than Attack. It learns some Psychic moves by level-up, like Confusion and Extrasensory. It also learns many status moves like Hypnosis and Reflect.
