Happens frequently on Ned's Declassified School Survival Guide to characters following a head injury. At times, only the bird sound effects play, but other times animated birds and other objects circle the victims' heads. Recipients of the trope in the show include Ned, Billy Loomer, Cookie and Faymon Phorchin.
Fittingly, Spike TV's Knockout Sportsworld often appends circling birds and stars around the heads of the athletes in its clips.
Nickelodeon's Roundhouse enjoyed playing with this trope. While injured actors usually only heard the bird sound effect, in the episode Disaster, a cast member spun a mobile of stars around Ivan Dudynsky's head after a fall, and a castmate remarks that she can tell he's injured because of the tweeting birdies. In another episode, Dudysky is clonked with an anvil and says that he sees "stars," as a castmate spins a mobile with cutouts of Cher, Whoopi Goldberg and other Hollywod big names around his head.
Jimmy of Out of Jimmy's Head sees circling birdies a couple of times after being bonked with a mallet.

Logan and Camille both hear birds in another epsisode, when they run towards each other in slow motion and crash hard. Logan, Carlos and James all hear birds in another episode, after dizzying themselves while spinning on a bat and falling. In the episode "Big Times Rides," James hears birds after crashing his motorcycle through a wall, and Logan and Carlos both hear birds when their wagon crashes into a car.
On this episode of his eponymous Nickelodeon series, Nick Cannon asks an animator to turn him into a cartoon. The animator obliges, drawing a sketch of Nick who gets hit with an Illogical Safe, resulting in the trope. Nick then rethinks the wisdom of wanting to be a cartoon character.
Happens to Nick in another episode, in which Nick gets knocked silly while trying to slide into home in a baseball game, leaving him on his back and hearing tweeting bird sound effects.

Alasdair, for one, hears tweeting birds after a hard fall from the ceiling in the Wildlife/Animals episode. In one of the later episodes, Christian hears birds after the coach hits him on the head with a baseball bat. Strangely, the show never used the sound during the caveman sketches, which usually centered on finding a way for the caveman dad to bash his kids in the head with a club.
Unfabulous uses bird sounds in the episode "The Toot." In a daydream sequence, Addie imagines herself passing gas with enough force to send her boyfriend Jake flying. He crashes into a soda machine and looks dazed as bird sounds play and soda cans clonk him on the head.

Saban Entertainment's live-action shows in the 90s frequently used bird sound effects to indicate head injuries, particularly on the original Power Rangers series. The comedy relief characters — primarily Bulk and Skull — were the chief recipients, although they occasionally were used with villains or even occasionally the heroes. Saban's Beetleborgs took it a step further and often added animated stars after head injuries, usually to Flabber, although one of the heroes, Roland, also saw stars a few times.

Happens to Dean twice in the Supernatural episode "Hunter Heroici." The plot centered around a comatose retirement home resident whose dreams of a cartoon world affected the reality around him. Dean first decides to test the theory by whacking himself on the head with a book, leaving him dazed and hearing tweeting birds. Later in the episode, the villain hits Dean with a frying pan several times, and he hears cuckoos. Additionally, in the episode "The Monster at the End of This Book," a meta-episode in which fanfaction is becoming reality, Dean experiences the stars variant in a somewhat lampshaded fashion. The fanfiction had a point that said "Dean saw stars." This became reality when Dean, having been hit by a car, comes to seeing stars before his eyes. He remarks on them, then it comes into focus revealing the stars actually are a pair of dangly star earrings worn by a lady helping him.
On the ANTFarm episode "Scavantger Hunt," Cameron sees miniature versions of Gibson circling his head after he's beaned with a bell. Disney used the episode as a sort of "Where's Waldo" game where viewers were supposed to count every appearance of Gibson, so the trope played into that.
In one episode of Lizzie McGuire, after Lizzie is knocked silly by her own locker door, the scene cuts to the cartoon version of Lizzie, who has stars and planets circling her head as seen here with some uh.. Cranial Eruption.
