Old Brown is a brown owl who sometimes wears eyeglasses.
Old Brown lives on an island called Owl Island in his tree. Hazelnuts also grow in Owl Island. The squirrels of the forest love hazelnuts, but Old Brown is always lurking around the island, so they have to watch out! Old Brown also hates being woken up from his naps by rabbits or squirrels, and hates when his eyeglasses are stolen! One of his skills is swooping down on the Squirrel Camp when they least expect it. He's also known for shouting, "Tailfeathers!" when he's annoyed.
A short-tempered owl who wants nothing but silence. Thus he would attack anyone who makes a sound within his vicinity. He constantly chases after Nutkin for disrupting the peace.
- He is a reason Squirrel Nutkin does not have a tail anymore.
