December 2, 2015 – Knobbed Hornbill or Sulawesi Red-Knobbed Hornbill (Aceros cassidix)

Requested by: @myfavoritecolorisbluh

These hornbills are endemic to Sulawesi and small nearby islands in Indonesia. They eat mostly fruit, including figs, as well as some invertebrates. Nesting in natural cavities, females seal themselves inside, leaving only a small slit which the males use to pass them food. They spend about a month incubating the eggs, then another three months brooding the chicks. Juveniles look similar to adult males with undeveloped casques (the ridges above their beaks). Around the age of 10 to 13 months, males develop larger, redder casques and females molt into their black head and neck plumage.
