You found a Pidgeotto!
Pidgeotto (ピジョン Pijon, Pigeon), known as the Bird Pokémon, is a larger and stronger form that Pidgey takes when it gains enough experience. It is a large raptor-like bird. While its primary color is brown, its plumage is much more elaborate than its pre-evolution, Pidgey. Its head-crest is much longer than Pidgey’s and is a reddish color. The plumage of its tail is also quite colorful, alternating between red and yellow. Other than its ornamental plumage, its basic coloration is similar to Pidgey, with pinkish-gray feet and black markings around its eyes. Pidgeotto is extremely territorial, generally claiming a large area with its nest built in the center. Full of vitality, it constantly patrols its territory, mercilessly attacking intruders. They fly about in circular patterns while hunting, and can spot the movements of their prey on the ground no matter how high they fly. Pidgeotto attacks with its wickedly sharp talons and carries its prey, including Exeggcute and Magikarp, back to its nest from as far as 60 miles away or more. Pidgeotto appeared in the Pokémon anime as one of series star Ash Ketchum’s first Pokémon. It eventually evolved into Pidgeot.
