Robins egg blue

I'm a black bird.
My egg is blue,
but all I see inside-
     — is you.
I love you all the same,
Even if you are not truly mine,
For one day I will teach you,
This world is just fine.
You will be taught to fly,
and I will ensure you are fed.
Others will scowl,
"A crow? A robin?"
"What an unlikely pair!"
It matters not,
We are both cowl,
and love for you,
     -I can share.
I love you all the same,
Even if you are not truly mine,
For one day I will teach you,
This world is just fine.
