ref The Oxford Dictionary of Nursery Rhymes Opie:

From "The History of Little King Pippin" c1786
Away,away, John Carrion Crow!
Your master hath enow
Down in his barley mow.

From "The Boy's Country Book 1839
We've ploughed our land, we've sown our seed,
We've made all neat and gay;
So take a bit, and leave a bit,
Away, birds, away!

From "The Nursery Rhymes of England" James Orchard Halliwell 1842
O you little blackety-tops,
Pray don't eat my father's crops,
While I lay down to take a nap,
Shu-a-O! Shu-a-O!
If my father he by chance should come
With his cock'd hat and his long gun
Then you must fly and I must run,
Shu-a-O! Shu-a-O!

From JOH 1949
Awa', birds, awa',
Take a peck. And leave a seck,
And come no more today.

From JOH 1853
Eat, birds, eat, and make no waste,
I lie here and make no haste;
If my master chance to come,
You must fly and I must run.

From Northamtonshire Glossary A E Baker 1854
Away, away, away birds;
Take a little bit and come another day birds;
Great birds, little birds, pigeons and crows,
I'll up with my clackers and down she goes.
