Pallium of avian species tend to be relatively large, comprising ~75% of the telencephalic volume. Birds have a unique pallial structure known as the hyperpallium, once called the hyperstriatum.

A 2002 conference at Duke University established a standard nomenclature for describing the avian pallium as follows:

• Pallium
  • pyriform cortex
  • olfactory bulb
  • hippocampus
  • corticoid area
  • hyperpallium
    • apicale
    • intercalatum
    • densocellulare
  • mesopallium
    • dorsale
    • ventrale
  • nidopallium
    • field L2
    • entopallium
    • basorostralis
  • arcopallium
  • amygdaloid complex
    • posterior amygdala
    • nucleus taeniae
• Subpallium
  • striatum
    • lateral
    • medial
  • pallidum
    • globus pallidus or dorsal pallidum
    • ventral pallidum
