|Behind the Scenes|
A Brutornis ("Heavy Bird") is the most massive of the Skull Island Terror Birds.
Standing five to six feet tall at the hip, and around nine feet at the top of the skull, Brutornis weighs in at around 500 kg. Equipped with powerful legs and large claws, Brutornis runs down prey in the open grasslands, dispatching its target with a single strike of its massive beak. Female Brutornis will nest on the edges of the grasslands and are highly protective of their eggs, often forgoing food for a month or so until the chicks hatch. Lycaesaurus will often entice a Brutornis female to leave her nest with other members of the pack dashing in and snatching up eggs. Those chicks who do hatch will follow their mother around until large enough to hunt for themselves.
- As stated by Peter Jackson during the commentary of the extended edition of King Kong, the Brutornis was based on a moa bird, an extinct bird native to New Zealand.
- The terror bird, also stated by Peter Jackson seems to be a mixture between a dodo bird and a moa.
- The Brutornis that appeared in the extended cut of the 2005 remake is the only creature to be an animatronic rather than CGI.
