''Coo-coo! Coo-coo!''

When a character in fiction makes an animal call, which is typically that of a bird. When used by a character makes a bird call, expect it to be for one of two purposes, neither of which are for animal reasons:
# As a signal.
# To pass it off as an animal.

Seldom played straight anymore, as it's very easy to [[PlayedForLaughs use for humor]]; typically, it will be either be for parody (the caller definitely does not sound like a bird, but it works anyway) or deconstruction (the bird call is out of place for the time or location, and the position is given away).

[[folder: Film ]]

* ''KungPow'': One of Evil Betty's henchmen calling out in a bird noise. Betty himself calls out a second later with, "I'm just a birdie too!" This may also be Type 2.
* In ''Film/ThreeAmigos'', Steve Martin's character calls in very badly done bird calls to get his co-stars' attention. Still, they assume it's a real bird. He eventually gets to "Lookuphere! Lookuphere! Lookuphere!" and finally resorts to just yelling, "Hey, you guys!"
* Parodied in ''Film/GalaxyQuest'': [[PluckyComicRelief Guy]] and [[TokenMinority Tommy]] stay behind to watch over the scene when the rest goes out to get fuel. The signal for something going wrong is a bird call, but, when they notice something ''really'' bad about to happen, they run out into the open screaming "Caw, Jason!" and frantically flailing their arms.
** What makes it funny is that Jason tells them they don't have to do bird calls since they have working communicators, but Guy and Tommy still do it anyway out of sheer panic.
*** [[FridgeBrilliance Jason did not have a working communicator at that time.]]
* [[PlayingWithATrope Played with]] in ''Film/DesertHeat'': [[JeanClaudeVanDamme Eddie Lomax]] and [[Creator/DannyTrejo Johnny Sixtoes]] perform coyote calls to alert each other. The calls are very clearly recordings looped in, though.
* In ''Film/InTime'', Phillipe Weis has a massive, bank-grade vault in his office. Contained within is a single capsule holding his collective personal wealth.

[[folder: Literature ]]

* Lampshaded in ''Discworld/MonstrousRegiment''. Polly, who knows something about birds, is exasperated by her squadmates' incredibly unrealistic bird calls.
** Similarly lampshaded in Discworld/GoingPostal. "Moist made a sound like an owl. Since he was no ornithologist, he did this by saying 'woo-woo.'"
* Played straight in Frank Herbert's ''{{Dune}}''. The Fremen use bird calls to communicate with each other: "Jessica heard... the distant bird calls that Stilgar had said were the signals of his watchmen."
** ...Birds... on ''[[DeathWorld Arrakis]]''?!
*** Presumably some variety of buzzard.
*** Perhaps you forget Paul's Freman name is Muad'Dib, which is a kangaroo mouse. Birds hunt mice. And a big scene takes place at a location called the Cave of the Birds.
* ''SwallowsAndAmazons'':
-->"Now, I haven't seen your allies and I'd rather not, but just you tell them from me if you ''should'' happen to meet them, that if they want to give a signal right bang in the middle of the day, it wouldn't be so hard on their friends if they'd choose blackbirds or jays instead of owls. Your Aunt Maria wants to write to the Natural History Museum about it. She says she's never heard one at mid-day before."
* {{Defied|Trope}} in ''Literature/ASongOfIceAndFire''. A character is told to make a bird call if she needs help. Her reply:
--> That's stupid. If I need help, I'll shout "Help".
** Gendry tells Arya Stark to hoot like an owl when she's taken care of a sentry. She replies that she's a wolf (the sigil of House Stark) not an owl, so she'll howl instead. But after [[TroublingUnchildlikeBehavior cutting the sentry's throat]] it's not her that howls, but a real wolf outside the castle. As Arya has the ability to bond with her direwolf which is roaming the Riverlands nearby with a large wolf pack, this may not be a coincidence.
* In ''Literature/TheHobbit'', Bilbo is sent to scout for danger, and told to hoot like a particular type of owl if he finds any. He's not given a chance to explain that he doesn't know how to, which becomes a problem when he does discover something.
* The heroes in ''Literature/TheWheelOfTime'' use a lot of bird calls as signals. Rand even makes a magic shield use a bird call as an alarm. They intentionally use ones out of place for the location to avoid getting confused by actual birds.
* Is played for laughs in ''Literature/BaptismOfFire''. Zoltan Chivay tells the gang he'll signal them by making a sparrowhawk's call. When they call him on not even knowing how a sparrowhawk sounds, he points out that if they hear a weird, unidentifiable noise, they'll know it's him.
* PeterPan's famous crow, often used as a signal to alert the Lost Boys to his presence. Additionally, the Indians use coyote cries as signals.
* For [[TheAdventuresOfTomSawyer Tom Sawyer]] and [[TheAdventuresOfHuckleberryFinn Huckleberry Finn]], the signal is a cat cry. Huck's apparently so good at it that on one occasion [[CatConcerto a man started throwing rocks at him through a window]].
* Used in ''Literature/TheHungerGames'' as a signal between Katniss and Rue. In a play on this trope, the girls sing or whistle four particular notes -- and then they rely on the mockingjays present in the arena to carry the song to where the other girl can hear it.
* Spenser Chapman mentions in ''The Jungle is Neutral'' how he used English bird calls in the Malaysian jungle in WW2, as to Japanese soldiers it was just another strange jungle noise.

[[folder: Live Action TV ]]

* Happens in an ''Series/ICarly'' episode where they have Freddy sneak into detention with them.
-->'''Carly:''' ''(like a bird)'' Caw-caw!\\
'''Freddy:''' ''(unconvincingly)'' Caw-caw...\\
'''Carly:''' Do it like a bird!
* Played for laughs on ''Series/StargateSG1''. A pair of bumbling scientists have decided to rescue the titular team, and one of them uses a bird call to attract their attention... on a spaceship.
--> '''Jonas Quinn''': Is that... a bird?
* One episode of ''TheWonderYears'' has a group of middle school kids plotting to sneak alcohol from their house late at night and use this to signal when the alcohol is recovered. When the kid acquires the alcohol, everyone else repeats the call over and over in unison and inadvertently wakes up kid's parents.
* Used in the ''UnnaturalHistory'' episode, "Maximum Insecurity" to lure the VillainOfTheWeek.
* On an episode of ''GomerPyleUSMC'', Sgt. Carter tells Gomer to signal him by hooting like an owl. When the time comes, Gomer says "Hoody-hoo, Sergeant Carter! Hoody-Hoo!"
* Done by GenreSavvy Abed in ''Series/{{Community}}'' episode [[Recap/CommunityS1E23ModernWarfare Modern Warfare]].
** Peirce also does this, to make people think birds are stealing Abed's food, not him. Except they're inside. And sitting right in front of him as he does it. They're all too stunned to do anything but stare.

[[folder: Video Games ]]

* ''VideoGame/{{Thief}} II'' has Garret use a bird whistle in the first mission. It's used to get your NPC companion to start his run to rescue his lover.
* Played straight in ''VideoGame/StarWarsTheOldRepublic'', where Republic players on Belsavis can be sent on a quest to find out how Rattataki convicts are repeatedly outmaneuvering Republic prison guards despite having no radios or other visible signals. One simple EscortMission later, the survey droid reports that there are always an increase in avian calls before an ambush, and closer inspection with advanced sensors reveals the calls are outside the range of the local fauna, finally explaining how the Rattataki operate. Future patrols are then sent out with devices that detect those artificial calls.

* In ''WesternAnimation/SouthParkBiggerLongerAndUncut'', Christophe the mole instructs Stan and Kyle that if anything goes wrong, to make a sound like a dying giraffe.
