Bird anatomy (The Angry Birds Movie)

In The Angry Birds Movie, the characters of the Angry Birds franchise are depicted with limbs for the first time. This article explains the variety of limbs that exist in the film and how this new aesthetic affects the original appearances of the Birds.

Overview
Birds are winged creatures with legs that end in talons. As Hatchlings, Birds are born with small wings and legs, and a fat, round body. However, as they grow, birds can develop unique body shapes, wings and legs.

Wingspan
In The Angry Birds Movie, the Birds have wings, which function exactly like human arms, instead of actual bird wings. Most Birds have a moderate wingspan, although there are some Birds who have short and small wings, such as Hal, and a few others with long ones, such as Stella. However, the colossal Mighty Eagle has proper wings which help him fly. A statue depicts this, carrying hundreds of eggs while several birds look up in awe at his heroism.

Leg length
Birds typically stand on legs that are not too long, although some variations of the length exist, as with wingspan. Stella and Gale have longer legs to appear tall, exhibiting a sense of athleticism.

Leg type
Birds are covered in feathers, which may also cover their legs as well, down to the talons. However, there are also birds who do not have fully feathered legs. In such cases, the unfeathered portion of the legs are covered with scales, like the talons. The color of the scales and talons usually match the color of the beak, although there are exceptions, such as Bubbles. Birds may have half-feathered legs, such as Chuck, or unfeathered, scaly legs, such as Stella.

Eye size
Hatchlings have abnormally huge eyes, which cover the middle-top of their face, but these progress into smaller eyes during adolescence. An example is clearly detailed by looking at the three blue birds, Jay, Jake and Jim. However, examining adolescent birds such as Chuck and Bomb shows their eyes being smaller than their body.
