beautiful blinding blue

And when he sings to you,
Though you're deep in blue, 
You will see a ray of light creep through,
And so remember this, life is no abyss, 
Somewhere there's a bluebird of happiness. 
Life is sweet, tender and complete, when you find the bluebird of happiness.
- Bluebird of Happiness, lyrics by Edward Heyman & Harry Parr Davies, 1934



 
Be like the bluebird who never is blue,
For he knows from his upbringing what singing can do
- Cole Porter, Be Like the Bluebird, 1934

 The bluebird carries the sky on his back. - Henry David Thoreau, Journal, April 3, 1852 

 
The bluebird is well named, for he wears a coat of the purest, richest, and most gorgeous blue on back, wings, and tail; no North American bird better deserves the name, for no other flashes before our admiring eyes so much brilliant blue.

 - Arthur C. Bent, 1949



Blue skies 
Smiling at me
Nothing but blue skies 
Do I see
Bluebirds 
Singing a song
Nothing but bluebirds 
All day long
- Irving Berlin, Blue Skies, 1927
