Crow brain

  • Brains body ratio:
    • Crow: 1:50, similar to chimpanzee
    • Pigeon: 1:150
  • Bird brain packs neurons more densely than mammals
  • NCL (nidopallium caudilaterale) in bird brain is similar to prefrontal cortex in mammal brain
  • Crow forebrain neuron number also similar to primates
  • Aesop’s fable: thirsty crow dropping stones into pitcher to get water level high. Repro’ed in modern experiments, crows had same success rate as 5b year olds
