Hero with a Wing

I see myself a hero
While one wings falls away
And the dial approaches zero
In a spiralling display
My past life flashes feverishly
And lives I did not lead
Like the time I was a hero
Of a weird, outlandish breed

One arm of flesh and muscle
And one of feathered scale
I was hero with one wing
That was of no avail
I could only fly in circles
Like a corkscrew in the sky
My one wing flapping frantically
While birds just glided by

I launched myself from mountains
And from the highest trees
And though I could get nowhere
Just landed on my knees
But still I was a hero
With one wing more than most
Almost half an Angel;
A whirling holy ghost

My father was an eagle
With two wings wide as sails
My mother was the west wind witch
With grasping finger nails
She lured him from his aerie
With her twittering device
She kept him in a golden cage
And fed him field mice
