Warning: animal gore ahead.
Most researchers accept that modern birds belong to a specialized subgroup of theropods (the clade encompassing T. rex and Velociraptor), making them perhaps the only branch of dinosaurs to have survived the Cretaceous–Paleogene extinction event 65 million years ago.
In light of this kinship, it never ceases to amaze me how many people are reluctant to associate birds with dinosaurs. Here's a fun game: next time you're hanging out with a group of friends, casually mention that T. rex is now hypothesized to have sported feathers. Not a few plumes here and there— we're talking literally covered in feathers. Now keep a tally of how many childhoods you've just ruined. People loathe a feathered dinosaur. "Dinosaurs used to be cool," said our own Esther Inglis Arkell on the matter last year, "[then] feathers came in, and now it's like, they're going to ruffle their plumage when they come after me, and that is not scary."
Wrong. I've emphased that last bit because, much as I love her, Esther is wrong. Feathered dinosaurs probably looked scary as all hell. In some instances, feathers may even have served a functionally lethal purpose. And are you seriously going to argue that ruffled plumage isn't scary? That's basically saying that modern birds, themselves, aren't scary. Which is bullshit. Birds, even the ones who eat mostly seeds and nuts, can be terrifying, bloodthirsty killers — and I guarantee you they only look more terrifying, their bloodlust only more apparent, with their feathers afluff. Case in slaughterous point: the Great Tit, pictured here:



Rather less well known is that the Great tit sometimes uses its relatively large size and powerful bill to kill smaller passerines, and indeed Barnes (1975) noted that "A topic of some interest to earlier writers was the alleged murderous tendency of great tits" (p. 112). Barnes described two or three cases where Pied flycatchers Ficedula hypoleuca were "found dead with smashed skulls in nest-boxes taken over by great tits" (p. 112), and also referred to occasions when Great tits had attacked and killed birds that were caught in traps, nets or cages. Caris (1958) reported a case in which an English Great tit was seen flying away with a dead Goldcrest Regulus regulus (one of Europe's smallest passerines: it may weigh just 5g). It had been killed by a peck to the back of the head. Its eyes were pecked out and its skull mangled.The upshot? Trifle not with the Great Zombie Tit. Do not question its strong ancestral ties with the fearsome dinosaurs of ages past. And let this be a lesson to us all that "feathers" and "fear" should never be regarded as mutually exclusive.
