  • Despite their large size, their bills are remarkably light, composed of a honeycomb-like matrix of bone and keratin.
  • While primarily fruit-eaters, they are opportunistic predators that consume insects, lizards, and the eggs of other birds.
  • They are secondary cavity nesters, utilizing hollows in tall trees formed by decay or abandoned woodpecker holes.
