  hi cake364den,
  hmm it depends on which species you are talking about. For example, a grey squirrel’s brain size is similar to a walnut but a parrot like great green macaws definitely have large brain size than a grey squirrel brain 🙂 it would be fancinating to compare the brain size in squirrel with parrot family
