Refrain from the kids' song "Six Little Ducks" goes:
He led the others
With a quack, quack, quack.
Quack, quack, quack,
Quack, quack, quack
He led the others
With a quack, quack, quack.

Refrain from the kids' song "Five Little Ducks" goes:
Mother duck said
"Quack, quack, quack, quack."
But only four [three, two, etc.] little ducks came back.

Then there's "Cluck Old Hen" and the like. But on to the more melodious birdsongs in songs...

The intro to "So Long, Farewell" from The Sound of Music:

There's a sad sort of clanging
From the clock in the hall
And the bells in the steeple too,
And up in the nurs'ry an absurd little bird
Is popping out to say "cuckoo".
(Cuckoo, cuckoo)
Regretfully they tell us (cuckoo)
But firmly they compel us (cuckoo)
To say goodbye (cuckoo) to you.

"Let's All Sing Like the Birdies Sing"
Written by: Robert Hargreaves, Stanley J. Damerell and Tolchard Evans - © 1932

Let's all sing like the birdies sing,
Tweet, tweet tweet, tweet tweet.
Let's all sing like the birdies sing,
Sweet, sweet sweet, sweet sweet.
Let's all warble like nightingales,
Give your throat a treat.
Take your time from the birds,
Now you all know the words,
Tweet, tweet tweet, tweet tweet.

Let's all sing like the birdies sing,
Bubbaboo ba-bubbaboo ba-boo.
Let's all sing like the birdies sing,
Tweet tweet tweet - my that bird sings sweetly.
Let's all warble like nightingales,
Ah, Mimi...c'est magnifique!
Take your time from the birds,
Now you all know the words
Tweet, tweet tweet, tweet tweet

"Hummingbird"
Frankie Laine

(Hummin', hummin', hummin', hummin'.)

Humming Bird, Humming Bird should be your name.
(Humming Bird should be your name.)
Too restless to settle, too wild to tame.
(Too restless, too wild to tame.)
Too restless to settle, too wild to tame,
Humming Bird, Humming Bird should be your name.

(Hummin', hummin', hummin', hummin'.)

Humming Bird, Humming Bird winging along.
(Humming Bird winging along.)
No tender young blossom can hold you for long.
(No blossom can hold you for long.)
No tender young blossom can hold you for long.
Humming Bird, Humming Bird winging along.

I'd rather be lonely, I'd rather be blue.
Yes, I'd rather spend my whole life without you,
Than feather a nest to be shattered apart,
By the hum, hum of your Humming Bird heart.
(Hum, hum, hum, hum.)

Humming Bird, Humming Bird, feathered so fine,
(Humming Bird, feathered so fine.)
If I clipped your wings it would not make you mine.
(Oh no, it would not make you mine.)
If I clipped your wings it would not make you mine;
Humming Bird, Humming Bird, feathered so fine.
(Hummin', hummin', hummin', hummin'.)

Humming Bird, Humming Bird, fly right on by.
Some folks like to gamble but darling, not I.
Some folks like to gamble but darling, not I.
Humming Bird, Humming Bird, fly right on by.

I'd rather be lonely, I'd rather be blue.
Yes, I'd rather spend my whole life without you,
Than feather a nest to be shattered apart,
By the hum, hum of your Humming Bird heart.
(Hum, hum, hum, hum, hum.)

By the hum, hum of your Humming Bird heart.
(Hummin', hummin', hummin', hummin'.)
