"Birds [...] are the last of the dinosaurs. Tiny velociraptors with wings. Devouring defenseless wiggly things and, and nuts, and fish, and, and other birds. They get the early worms. And have you ever watched a chicken eat? They may look innocent, but birds are, well, they're vicious."
Everybody knows that birds are some of the least scary animals ever, right? After all, they're small, they're pretty, they sing, they have sharp claws and pointy beaks, they fly around in huge flocks, they hang out in battlefields and pick the flesh off of the corpses...
Monstrous birds aren't that ridiculous, if you think about it. After all, they're the dinosaurs that survived. As mentioned above, even the cutest birds have pointy beaks and claws, and some birds (such as starlings) fly in flocks of thousands, making them seem like hordes ofavianlocusts. Many of them are voracious predators, and airborne to boot - just imagine if they were big enough to swoop down on humans and carry them off. (It might be worth noting that the extinct Haast's eagle could have occasionally preyed on humans, although it wouldn't have been able to carry them. The giant teratorn could theoretically have carried off a person weighing up to approximately 95 kg/200 lbs, had humans actually been around when it was alive.) One should not forget the TERROR BIRDS, that once roamed (and likely terrorized) the earth.
Feathered Fiends can be divided into four catagories:
Parodies and Subversions. Much like other cute and seemingly harmless animals, some birds are portrayed as evil or dangerous to subvert common expectations. Killer chickens and villainous ducks are probably the most popular variation. When this one is played completely straight, it frequently results in Narm.
Wolfs Rain: While looking for a way out of the Forest of Death, the wolves get freaked out by a creepy talking owl that might be a ghost. One of its cryptic pronouncements does does turn out to be a clue to the escape route, though.
Confirmed. After the gang discover the bones stripped bare by the bugs, if you watch the next shot of the owl you can see the trees through it as it flies away.
The evil Raven from Princess Tutu, and to an extent his daughter Princess Kraehe (Crow), and the flock of carrion birds that are associated with them.
The first episode of Pokémon had a rock throwing incident lead to Ash and Pikachu being chased by a flock of Spearow (whose Japanese name means "demon sparrow").
The same Spearow returns at the end of that season, evolved and looking for payback...
Also, the Taillow, which are also very aggressive if their food sources are threatened. Furthermore, they are able to resist electric attacks (which should be super effective against them) by sheer willpower.
Even Pidgey, which is said to be mild mannered, can generate winds strong enough to blow a ten-year-old into the sky.
All Murkrows in the series are a species of Jerkasses as their hat. Pun not intended.
In Chrono Crusade, Aion first appears by channeling his voice through his familiar—a bald eagle with glowing red eyes. Probably meant to be creepily symbolic, considering Aion constantly cites his motivations as "freedom".
Dio Brando's pet falcon Pet Shop is just as sadistic as his master, and even has a Stand (Horus, appropriately enough). He's even capable of flashing a Psychotic Smirk, which even Team Pet Iggy notes is impossible.
Most Bird-type Digimon are heroic or neutral, but the massive Ultimate-level Parrotmon is definitely a fiend, especially in the first movie.
Noise, the real Big Bad from Suite Pretty Cure ♪ is a giant black bird with a dragon head and dragon tail. He's able to brainwash people with the Noise of Evil, controlling all other villains. After absorbing Trio the Minor, he gets a humanoid form, but he's still a Feathered Fiend.
If Gaston La Gaffe's seagull is in a bad mood, the whole office runs for cover.
Savage Dragon features a villain named Powerhouse who is an avatar of a nature-god. He looks like a humanoid chicken but despite his ridiculous appearance, the hero of the series soon finds that he is a Not-So-Harmless Villain.
This was, of course, carried over into Stephen Sondheim's Into the Woods.
Two fire-breathing turkeys appear in Madame d'Aulnoy's The Yellow Dwarf.
A Growing Affection has the Shadow Roc, a giant demon bird large enough that all nine Bijuu could fit on its wings, but still not quite as powerful as the One-Tails. It's still a pretty nasty piece of work, brokering a deal with Orochimaru to Mind Screw its six-year old host so it can take over her body.
Films — Animated
Lord Shen, the Big Bad of Kung Fu Panda 2, is a villainous peacock with the blood of apparently the Panda species on his feathers, making him a Type D. However, he is largely no joke in battle considering he is genuinely threatening with his blades when he fights hand to hand.
H. G. Wells wrote a short short called Aepyornis Island, where the titular bird is quite a nasty beastie. The real Aepyornis was herbivorous, but since their still living cousins like the cassowary are among the most lethal birds alive...
Whippoorwills often appear in Lovecraft's stories as omens of impending doom. They don't actually do much, but you know something ugly is about to go down when a bunch of whippoorwills decide to perch near your house in Lovecraft Country.
The Chimes of Death from the Sword of Truth series, AKA the infamous "Chicken That Was Not A Chicken". Aims for Type A by being a demon that takes the form of a seemingly-ordinary chicken, but regarded by many readers as an unintentional example of Type D.
The birdwoman from Anansi Boys (quote featured above) serves as a secondary antagonist, using birds to attack Fat Charlie and Spider.
There's a children's book called "SQUAAAAWK" in which, if you open a magical book, you allow the Roc magically bound inside to get out and terrorize your town.
The later Animorphs books have several instances of flocks of homicidal bird-morphed controllers attacking the protagonists.
And the natural version: Tobias hates crows because they mob hawks. And eagles—a group made Rachel slam into a tree and lose her memory.
In Redwall, birds are generally on the side of good, if often wild and untamed. There are exceptions, however—an army of rooks led by a raven attacks Redwall in Mattimeo and St. Ninian's is home to vicious jackdaws in Pearls of Lutra. And, of course, there's the heron of Martin the Warrior, the Warden. "I am the law!" * GULP*
Swans are (somewhat justifiably) treated as giant monsters in one book, where the heroes trick some henchmen into getting close to a swan's nest. Death ensues.
The Old Kingdom Trilogy has flocks of Gore Crows, evil and dangerous in large numbers (especially when in a Paperwing); a flock of crows animated by a single Dead spirit.
The enormous flocks of sparrows of Stephen King's The Dark Half. "Evil" might be putting it a bit strong, since their ultimate purpose is to put the main character's Evil Twin back where he belongs; then again, "creepy" might not do them justice.
In Dragaera, the issola is a sort of crane-like which appears really elegant and graceful, but is also a very competent hunter. This is noted as a metaphor for how the House of Issola has the hat of politeness and grace, but you shouldn't think they are pushovers.
His Dark Materials has the tualapi, white swan like birds that are flightless but use their wings as sails...and are carnivorous. Perhaps a subversion however, since they may not actually be birds, but organisms that evolved to resemble them, since they belong to a world were vertebrates aren't the dominant animals, and their wings are positioned one in front of the other instead of alongside each other.
Some of the Dark One's servants in The Wheel of Time can use crows as spies and messengers, and occasionally use huge flocks of crows to attack people. Crows are regularly included in scenes to give the impression that characters are being watched.
Both played straight and averted in Lord of the Rings; while crows are viewed as an ill omen, and a malicious variety called "crebain" serve Saruman as spies and messengers, ravens are noted to be dwarf-friends. And the Eagles are downright Always Lawful Good.
In the Warrior Cats series, ordinary birds of prey such as hawks, eagles, and owls. Justified, since they're cats, after all, and the birds are very large to them - large enough to carry off a kit, or, with an eagle at least, a full-grown cat.
Inverted in The Twits . Roly-Poly Bird and the other birds are instrumental to the escape of the monkey family and the turning of the Twits upside down.
While Walking With Beasts focused mostly on prehistoric mammals, the horse-munching Gastornis in the first episode was one of the scariest animals on the show. Although a bit of Badass Decay occurs when its unhatched chick is eaten by giant ants. Also of note are the Phorusrhacos in another episode, though they don't present any real threat to the Smilodon we're following. Because nothing - except climate change and the giant ground sloth Megatherium - present much threat to a Smilodon.
The titular character of The Avengers episode "The Winged Avenger". A cartoonist who disguises himself as his own bird of prey-like comic superhero and lacerates Corrupt Corporate Executives to death, using magnetized boots to climb walls.
The Tales from the Crypt episode "Carrion Death" has the protagonist, a con attempting to escape through the desert, being stalked by a hungry vulture who eventually makes a meal out of him... while he's still alive.
While vampires were later associated with wolves and bats, Roman legends portray them as shapeshifting, blood-drinking owls. Several East European words for "vampire" (strigoi, shtriga, strzyga) are derived from "strix", the Latin word for "screech owl."
Vampire: The Requiem uses them with the strix, spirits that take the form of owls who brought down the Roman Empire (and with it, the largest body of vampiric government in history) because of an ancient betrayal. They can possess humans as well as sleeping vampires, and the clan books hint they're returning for some reason...
Harpies, which are usually portrayed as vulture-like.
Sirens also originally were depicted as birdlike rather than mermaid-like.
Quite few other mix-and-match mythical monsters are at least part bird, although whether or not they're scary of evil tends to vary.
One of Hercules's tasks was to kill the Stymphalian birds, which had sharp, metallic feathers and a taste for human flesh.
Averted (mostly) in Norse Mythology with Odin's two ravens, Huginn and Munnin.
Do you know that stereotypical image of hundreds of hapless slaves being dragged up an Aztec pyramid to have their hearts torn out? That was the festival of the Aztec god of war Huitzilopochtli, the Left-Handed Hummingbird.
The thunderbird of Native American mythology.
The boobrie from Scottish folklore was a monstrous, shapeshifting water bird that was large enough to kill and eat sheep.
The Kroot of Warhammer 40,000, while not feathered anymore, are a sentient humanoid race descended from avians. They have a mane of quills instead of hair or feathers, but retain their ancestors' slender yet powerful build, language of clicks and whistles, sharp vision, and beaks. The Kroot are notable for consuming the flesh of defeated enemies in search of specific evolutionary upgrades - in the 41st millenium you get eaten by chickens.
In Gamma World, there are a few including the Gallus Gallus, chickens that were being bred for meat, but after the apocalypse the computer breeding them screwed up and now they're sentient and humanoid. There's also the Carrin, cruel psychic vulture people with nasty quills.
Speaking of nasty bird poeple, the word "Blackwings" comes to mind.
And don't forget the RAPECROW!!! (Alright, it's called Depraven, but the idea is there).
GURPS Technomancer, of course, has the magic-using penguin socialist collective of Antarctica, transformed by a Hellstorm into a vicious hivemind that has driven human scientists from the continent and is building up for the next clash.
Werewolf: The Apocalypse has the Corax, wereravens. While not evil as a rule and actually relatively pleasant compared to the title lycanthropes, they still have a very disturbing half-human, half-raven war form. It's made all the worse by the fact that they know how gross they look in this form so if they are forced to use it they are usually very, very angry.
In Borderlands, Mordecai's pet Bloodwing can be used as an attack on enemies.
Chocobos in Final Fantasy games. There are few enemies nastier than a flock of them.
The Yagudo are one such enemy. I mean honestly, some of them can be called katana-wieldingSamuraibirdmen. The fact that many Yagudo are religious fanatics doesn't help matters, although they at least have a 'peace' agreement with Windurst (read: give us offerings or we'll overrun the city).
There is also the Zuu, ugly, featherless Giant Flyers that tend to do more damage to the party then any other monsters on the map.
In Final Fantasy VII birds/flying enemies approach Demonic Spiders territory at times, due to high-damaging skills (the penguin things around Cosmo Canyon early in the game) or the fact that you cannot hit flying enemies without long-range equipment or materia (like the Unknown in the sunken carrier.)
The Curse of Monkey Island has "El Pollo Diablo", a demonic chicken that pirate/restaurateur Blondebeard is convinced ran off with all his chickens. Part of a solution to a puzzle involves getting Guybrush to disguise himself as El Pollo Diablo.
Also, the folk legends of unsuspecting (and supposedly quite powerful) feather hunters being killed by regular chickens, on which the Evil Chicken was based.
There's also the Baby Roc and its mother, the Roc in the My Arm's Big Adventure quest, who have to be defeated in order to help a troll fulfill his dream of being a gardener.
Averted with Armadyl, his Aviantese followers, and the Saradominist Icyenes, all winged humanoid warriors. They are/follow the self-professed "good gods" of Gielinor, although evidence suggests that the Icyene may not have had much choice in the matter.
Vulcan Raven's rather disturbing death in Metal Gear Solid A flock of his namesake birds descend on his body, and when they leave, nothing is left but his weapon.
Swarms of small flying creatures have been in Metroid games ever since the first, althogh they are most prevalent in the 3D installments, where they tend to appear as very large flocks, often flying around in circles in large rooms.
In Heretic II multiplayer, there is a 10% chance that hitting somebody with a Morph Ovum (90% into a small pathetic chicken) will turn them into 10 ft tall, 999 hp demonic chicken who's steps shake the ground, and who's peck causes instant death.
In Halo, it has been strongly hinted that the Kig-Yar (or, to humans, 'Jackals') of Halo are of avian ancestry, with several characters directly comparing them to birds. The novels describe them as vicious Space Pirates and Prophet-employed mercenaries who will do anything for money or spoils of war.
In fact, their chicks are covered in down, while the Skirmisher subspecies develop all-out plumage as adults.
One of the Dead Apostle Ancestors in Tsukihime is half bird, half vampire and has numerous bird minions and a Reality Marble having something to do with black feathers that kill people. Even the other DAAs don't like him.
Evil birds show up quite frequently in the Sly Cooper series. The most prominent is Big Bad Clockwerk (an owl), but the second game also gives us sinister parrot Arpeggio, and the third has an evil chicken (General Tsao) and another nasty parrot, the pirate captain LeFwee.
EarthBound has a number of avian enemies, like the Spiteful Crow and the Mad Duck.
Bobo in Wario Land 1 is type C (although the latter games show it as closer to a pterodactyl/dragon than any bird), as is the true form (after the first half of the boss battle is won) of Cuckoo Condor in the fourth game.
Summoner 2 lampshades this; there's a corvid sitting by a fire in an ominous-looking jungle filled with ruins, where a bloody battle had taken place in ages past... however, his name is Matthew, and he's a rather nice fellow. He even loans you his boat.
Baten Kaitos Origins has the Holo Holo Bird, a giant, jungle-dwelling That One Boss whose difficulty is exacerbated by its minions, adorable babies who have the obnoxious habit of constantly healing their mother for thousands of damage points.
Mystia Lorelei of the Touhou Project qualifies on one angle, being a night sparrow youkai who hunts humans and can strike them blind with her singing. However, she also averts this trope, as The Chew Toy of many a poultry joke in both canon and fanon.
There's two in Donkey Kong Country Returns, Savory Stu and Colonel Pluck. The former is a giant bird whose body is in a giant cauldron filled with bombs and the latter is an anthropomorphic chicken piloting a giant robot. The latter's stage name and theme is even called "Feather Fiend"!
Archeops from Pokémon Black and White (a prehistoric semi-flightless bird based on the Archeopteryx) has beastly attack and good speed. Unfortunately, it's a Glass Cannon, and its attack and Special Attack are halved if its health gets below half.
Braviary (based on a bald eagle and using a misplaced hawk scream) is capable of carrying away cars, and it won't stop fighting even if injured, for the sake of its friends. It also has a red, white, and blue color scheme. Hmmm...
Going as far back as the second generation (IE: Gold, Silver, Crystal), we have Lugia. A giant-sized bird monster that resembles a dragon-esque monstrosity. Not only was it worshipped as a god in ancient times within the games mythos, but it was said to be so powerful that it could create storms by a single flap of its wings. It was also responsible for (accidentally) causing the storm that destroyed the Brass Tower and killing the three Pokemon inside that would later become Raikou, Entei, and Suicune. Luckily, though, Lugia isn't malevolent and would prefer to dwell peacefully at the bottom of the sea.
Shadow Lugia is basically the result of what happens when one forceably turns an otherwise peaceful dragon-bird monster evil. In the first cutscene alone, it aids the villains in hijacking an entire ship leaving several innocent people stranded in the ocean.
Lugia is also the master of the Legendary Bird Trio, Arcticuno, Zapdos and Moltres, who nearly destroy the world in the second movie because of a greedy human's meddling.
Pokemon X/Y gives us Yveltal, a Pokemon that looks like a giant horned vulture. To make matters worse, it is known as the "Destruction Pokemon" and it can resurrect itself from death by forming a cocoon and draining the life out of everything nearby.
The Babylon Rogues of Sonic Riders are a ruthless gang of thieves made up of Jet the Hawk (who looks more like a parrot), Storm the Albatross, and Wave the Swallow.
Which is really odd when you realize that Real Life Albatrosses are endangered and swallows and martins have adapted well with humans.
This is played as Type D in Dragon Age: Origins. Shale hates all forms of bird because she had to live as an immobilized statue for many years, conscious the whole time, and pigeons would frequently sit and crap all over her. She's now made it her life goal to drive all the birds in the world to extinction, starting with the pigeons.
The giant two-headed roc from King's Quest V. Also subverted in that the only way to escape from said bird is with the aid of another bird whose life you saved earlier in the game.
In addition, Tomb Raider II features the Guardian of the Talion, a huge, hulking creature with a bird's head and talons and a humanoid torso and limbs. The Golden Mask add-on features a similar creature, the Guardian of the Kingdom.
Pigeon: Impossible stars a rather...persistent pigeon who demands a CIA agent's bagel, and in doing so nearly causes a nuclear holocaust.
In Worm, one of the Endbringers (three gigantic, incredibly powerful, seemingly invincible creatures that appear to be on a mission to destroy humanity) is a fifteen-foot-tall bird-woman with multiple wings called the Simurgh. She is described as the most intelligent, subtle and manipulative of the Endbringers, with a variety of Psychic Powers that she uses to trick people into eventually ruining their own lives as well as the lives of everyone around them.
The Batman: The Animated Series version of the Penguin had a collection of deadly birds ranging from poison-billed hummingbirds to trained attack-cassowaries.
Buzz Buzzard from the Woody Woodpecker cartoons was usually shown as genuinley evil and sinister, as opposed to Woody who was just an obnoxious Screwy Squirrel type.
Count Duckula began as a show-biz addicted ditz on Danger Mouse before becoming an actual villain. He became Flanderized on his own show (a hapless show-biz addicted vegetarian) and had to deal with a common foe, vampire hunter Dr. Von Goosewing. Duckula's manservant, Igor, may count as sinister as he prods Duckula into being the evil bloodsucker he was intended to be.
Roosters have spurs on their legs. Roosters are apparently territorial. There is a reason why Cockfighting used to be so common. Sometimes their natural spurs would replaced with razors.
The vampire finch (Geospiza difficilis septentrionalis) is known for pecking at other birds and giant tortoises until it draws blood, and then drinking it.
You know oxpeckers, those cute little birds that perch on animals in Africa and do useful things like eat their hosts' parasites? What they're actually after is blood. They mostly get it from the ticks they eat off their hosts, but sometimes they try to get it from the hosts themselves.
It wears a black mask. Don't say you haven't been warned.
Geese can be very vicious if their brood is threatened. They're sometimes used to guard other poultry from predators.
A lot of birds are very protective of their nests. While their protective instinct is entirely understandable, getting swooped at by alternately furious and desperate parents and helpers for walking near the wrong tree is alarming.
Seagulls are likable when it's not the nesting season. When it is, seagulls turn into divebombing feathered fiends from hell.
The aptly namedterror birds took over the role of giant bipedal predators in the Cenozoic, long after non-bird dinosaurs were extinct.
Also, Gastornis, which filled a similar role somewhat earlier than the terror birds.
The Cassowary, native to Australia and New Guinea is a large ostrich like bird. The avian equivalent of a Bear, a Cassowary is dangerous for all the same reasons. They've killed people on more than one occasion. They are extremely territorial and agressive (even more so when it's a Father Cassowary with chicks because it's actually the males that care for and protect the eggs and chicks). Their back legs kick with enough force to colaspe a human rib cage, or crush a human skull, and has a dinosaurian killing claw on the end. Their omnivorous diet means they love to go into human residental areas and eat trash, because it's loaded with the rotting fruit, bugs, and small mammals it loves to eat. Unfortunately, this means they're more likely to encounter humans, and attack them for invading what they consider to be "their" territory. They've also been known to kill dingos, crocodiles, and even horses and cattle that get to close.
Steamer ducks. They attack and kill other waterfowl for no clear reason.
Great tits prey on hibernating bats by ripping their heads off. These birds are definitely not just seed and insect eaters.
Whether or not they count as birds is up to you, but the predatory dromaeosaurids and caenagnathoid oviraptorosaurs definitely bore bona fide feathers. Among the dromaeosaurids were Deinonychus and Velociraptor, but the largest of them was Utahraptor, which was at least the size of a grizzly bear and, based on rumored undescribed remains, may have been even larger. Grizzly-bear sized raptors. That might have hunted in packs. The largest oviraptorid was Gigantoraptor, which was almost nine meters long and weighed over a ton, comparable to some tyrannosaurids like Albertosaurus. It would have been the largest feathered fiend known to science if you only count dinosaurs with pennaceous feathers. If you throw protofeathers into the equation things get muchmorecomplicated.
They were also very tenacious when defending their nests (which was probably done by themales, by the way). It appears that they would even try to shield their eggs from a sandstorm, as many oviraptorid fossils are found crouching over their nests.
There's this new theory about how dromaeosaurids went about "preparing" their prey: They used their sickle claws to pin their prey down while flapping their wings for balance. Now put yourself in the prey's shoes: You're lying on your back with raptor claws hooked in your skin, and huge wings flapping in your face, while a raptor eats your guts out. The point is... you are alive when they start to eat you.
If you count protofeathers (primitive hair-like feathers), the amount of Fiends grows even higher (and it includes TYRANNOSAURS
An ostrich once nearly killed Johnny Cash by gutting him with a kick (he was running a farm of them at the time).
There are stories - unconfirmed - of massive eagles carrying off dogs and even in one case a small child (who survived, was found in the mountains miles from where she disappeared, and is the source of the story).
African Crowned Eagles have been known to launch predatory attacks on children (Up to seven years old!). Also, skulls of human infants have been found in African Crowned Eagle nests. This is also the same species of eagle that killed our hominid ancestors as mentioned by the troper above, and because of their fiercesness and fondness for primate meat they are known as the "leopards of the air" by certain African peoples.
While hummingbirds are largely harmless to humans, they're viciously territorial, due to the fact that they need to eat so much to keep flying. If a hummingbird isn't eating, it's probably fighting. The Aztec example above may have been the result of good observation.
