You would think different systems in different species would make for different vocal cords? Not true when it comes to songbirds.
If you didnt know, the song birds have the same vocals as us, it just works in a different way.
What makes it different is how we take in air.
The lung placement is different too! How our lungs are openned are down and out, like a balloon.
But birds are just out. How that affects is our muscles inbetween our ribs, also known as the 'Intercostal Muscles', are not used to functioning like that.
As your lungs take in air, they expand and open your ribs up.
At the same time, they are pushing down on your stomach and intestines and all of that stuff, so that in turn is pushing it out due to lack of room for movement to go anywhere else anyways.
Songbirds have the lungs that just expand. Thats why in movies, and in real life, the song bird takes a breath before singing.
We do have a lot in common with animals!
