Dino Birds (Ice Age: Collision Course)

The Dino-Birds are the main antagonists of Ice Age: Collision Course. They consist of three characters named Gavin, Gertie, and Roger who were trained to steal eggs.

Why They Need To Go Extinct

 * 1) Compared to many of the Ice Age antagonists, the Dino-Birds are by far the worst antagonists to ever be put in an Ice Age movie all because of their role as the villains in Ice Age: Collision Course which will be discussed further.
 * 2) Their motives are lame which only consist of them flying out of range as high as possible in the atmosphere just because an asteroid will hit Earth. That is so unrealistic because even if they fly away as high as possible, they can still die. Even if they managed to survive somehow, the food supply would be hard to obtain. What's worse is that Gavin stated that the Earth could be a paradise when the asteroid is deadly.
 * 3) Gavin is supposed to be the dad dino-bird, but there are instances where he is so ruthless that he only cares about getting revenge for Buck instead of stopping the asteroid. Did he not realize what would happen if the asteroid would hit Earth.
 * 4) Both Gavin and Gertie keep treating Roger like trash just because of how rational he is compared to the rest of the family. That is basically neglecting their own relative due to different views. As a result, Gavin is biased towards Gertie due to Roger's character.
 * 5) They are one of the new characters in Collision Course that never got a proper introduction as to how they came into the other characters' lives thus only to a random start for them from the start to finish thinking that they could just appear in a snap.
 * 6) Gertie at one point of the film acted spoiled towards Gavin just because Roger kidnapped a mammal (though he was assigned to get Buck and got Granny instead, still) thus getting rewarded. It's like she is being an attention hog in that scene.
 * 7) Their redemption arc, when they team up with the main herd, feels cliche and forced.
 * 8) Gavin has some ego in him during the film. He seems to see himself as a smart and capable dino-bird when the story states otherwise.
 * 9) Overall, they don't really qualify as villains who don't really do justice to the plot as the asteroid is the main villain of the film. Yes, the asteroid is not a character, but antagonists don't need to be a living thing to qualify as a villain. It's basically character vs. nature conflict instead yet Collision Course expects us to root against them (though they redeem themselves).

Redeeming Qualities

 * 1) Gavin does treat Gertie with respect despite favoritism. Even if he treated Roger like crap, he reconciles with him during the climax. And let's not forget to mention that Gavin does protect them.
 * 2) Gavin stopped trying to get revenge on Buck just to help the herd divert the asteroid. If it weren't for Roger, Gertie, and Buck, then none of this would've happened.
 * 3) Roger is more rational compared to Gavin and Gertie.
 * 4) Their voices sound decent. Thanks to Nick Offerman, Stephanie Beatriz, and Max Greenfield voicing them.

Trivia

 * The Dino-birds are the first species of dinosaurs to be shown fully speaking like the mammals in the franchise.
 * The Dino-birds were probably Dakotaraptors, which were discovered in 2015 and lived alongside Tyrannosaurus Rex. This can be noticed especially in the large 'killing claw' on the Dino-Birds, which were present on raptors and raptor-like dinosaurs in the past.
 * Real Dakotaraptors and other Dromaeosaurs could not fly, unlike the Dino-Birds portrayed in the movie. However, one genus of crow-sized Dromaeosaur, Microraptor, was capable of limited flight due to the presence of well-developed pennaceous feathers on both its arms and its legs.
 * Unlike other dromaeosaurs in pop culture, the dino-birds were given both scales and feathers, including wings and a tail fan, which they had in real life. However, in dromaeosaurs the feather covering would have been similar to that of extant birds, covering almost all of the body, minus the bottom of the feet, the tip of the nose, and possibly the shin. This difference can be explained in the same way as the previous one.
