The Unbearable Chirpness of Birdies

Birds are imbued
With hammer and chisel
To peck at the temples
Of those who are near.
Noise is a constant
For budgies are talkers
Hamm'ring my head
Their chisels like spears.
Simile glut?
Poetically loose?
Perhaps it is so
And that's what I fear,
But jackhammer birds
And the aching they cause me
Get in my head
And summon up tears.
Gah, they're obnoxious!
Never relenting,
Chirping as if
They've got deep-seated fears
Of losing their voices,
Descending to muteness,
And so they chirp on
With incessant jeers.
