Griffember day 7 (#84) - black-and-white-casqued hornbill (LC) [rough reference]

Took two days on this because I had to do these birds justice; they're definitely my favourite hornbill and just one of my favourite birds overall. Very dinosaur.

For the helmeted hornbill, safety always comes first-- that's why these birds have their own 'helmets'! Males compete for females by headbutting each other in mid-air, and their heads are protected by large, bony structures called casques that protrude from the beak. In most hornbills the casque is hollow, but for the helmeted hornbill it's completely solid, making up 11% of the bird's total weight!

Male and female birds can easily be told apart by their eyes. Males have red eyes with black rims, while females have white eyes with reddish rims.
