Birds are smart. 

Birds are actually really smart. They can learn to speak our language, feel grief and depression. My own parakeet can open her cage door and enjoy freeeeedom!!!!!!!!!!!!!!! Crows and ravens are also very intelligent, they are one of the ten most intelligent creatures on this planet. But despite the term "wise owl"... their not wise. They have eyes too large to have maximum brain capacity.

Parakeets have the mental capacity of a full grown three-year-old. I guess that's not much but hey, their brain is the size your little finger's fingernail!
