Caroll Spinney, the actor and puppeteer behind Sesame Street's Big Bird, is saying goodbye to the role as the big yellow bird which he brought to life almost 50 years ago.

If you are reading this, chances are you grew up watching Spinney as Big Bird teach us about the big and little things in life: how to be a friend, how to count and sing and much more. Spinney, who is also leaving his role behind as Oscar the Grouch, says Big Bird taught him as much as he taught us.

"Before I came to 'Sesame Street', I didn't feel like what I was doing was very important," Spinney said in a statement. "Big Bird helped me find my purpose. Even as I step down from my roles, I feel like I will always be Big Bird. And even Oscar, once in a while!"

The puppeteer is widely respected and admired for being able to embody two of the world's most loved, but most different characters: from Big Bird's open, loving personality to Oscar's grumpy outlook on life. Spinney dabbed into puppeteering as a child and teen and even used his talent to pay his college tuition. He joined the Sesame Street Muppet cast as Big Bird during its first season in 1969. As Big Bird, Spinney traveled the world going to China with Bob Hope, and later Japan, German, France, Australia, United Kingdom and Canada.

To honor Spinney's run, here are some of the moments he shared with us as Big Bird:

There's no bigger cheerleader than Big Bird and in this scene, he helps cheer up the number 1, who's not feeling up to his reputation. 

How he taught us about emotions that aren't so easy to identify sometimes

It's not always easy figuring out how we feel, but Big Bird has been able to help us identify different emotions and feelings. 

But most of all, his adventurous spirit:
