Diatryma – Diatryma gigantia R., ten foot tall, flightless birds, members of the Thunderbird (Adar Taranus) Dynasty which originally escaped extinction by the Mwyaf Fawr Llosg or Greatest Burning, when the rest of the Dynasty was exterminated, only to mysteriously become extinct a few million years later. They were accidentally revived from fine Eocene shales by the wizard Razzorbauch when he penetrated the Earth’s crust while forming the magma chamber for the Fudge Volcano. They are omnivorous, opportunistic feeders that are capable of downing and dismembering small ungulates. They are covered with deep iridescent green plumage. Their tail feathers and primary flight feathers have brilliant red and yellow patches on each feather’s trailing blade that remain completely hidden unless the bird is displaying. Their bony tails are not entirely fused into a pygostyle as in modern birds, but rather consist of a pygostylic terminus at the end of ten un-fused vertebrae, giving the birds a fan of feathers that can be waved about on the end of a flexible tail. There is nearly no sexual dimorphism, though males tend to be a few percent heavier and have deeper voices than the females. They are exceptionally intelligent, having a brain cavity of about 650cc, or roughly half the volume of modern humans. However, being far less fatty than a mammalian brain, this is a very respectable computer. Possibly due to natural selection pressures favoring the keeping track of stashes of food morsels, diatrymas seem to have little or no barrier between the conscious and subconscious minds and have instantaneous recall of all the details that they once observed during any previous experience.
Mary the White Witch’s mounts and closest friends are Ceidwad the female diatryma, who is the wife of Lladdwr and the mother of Arwr, their cockerel. Razzmorten describes these three as the most intelligent beings he has ever been in the presence of, and they become key characters in the tale of The Heart of the Staff, (books three through six, Stone Heart, The Burgeoning, Reaper Witch and Doom). Ceidwad and Lladder were brought back to life by accident by the evil Wizard Razzorbauch and were raised by the Fairy sisters in Mount Bed before their association with Mary. Perhaps their most stunning talent is being able to listen to a language for a short while and then suddenly start speaking it fluently.
What sorts of birds tower in your imagination? Do they play a role in your dreams?
