I found this on Urban Dictionary...

1.yellow bird

a person's true love; the one person they are both externally and internally, both consciously and subconsciously attached to with the realization that those feelings will never die; the one person that they know they can't live without

if they find this person, they are the luckiest in the world. if not, they are eternally screwed.
