Next, I decided to look inside and find out what these birds are made of. The following is a skeletal drawing based off of my research. Like plenty of other animals, they're not too far off from the human skeleton. If you were to cut off everything past your ribs and attach smaller versions of your legs to your spine, you'd be pretty close to a bird!
I never knew this but birds have an enormous sternum called a Keeled Sternum covering most of its chest/belly area.
The femur(upper leg bone) is partially visible from the outside but is mostly hidden within the body.
The wings looks very similar to arms except their humerus is shorter, and their metacarpals and phalanges are extended.
