Up on the ridge for weeks -
I said nothing at the time
But I never liked yon bird'
The automatic lock
Clunks shut, the blackbird's panic
Is shortlived, for a second
I've a bird's eye view of myself,
A shadow on raked gravel
In front of my house of life.
Hedge-hop, I am absolute
For you, your ready talkback,
Your each stand-offish comeback,
Your picky, nervy goldbeak -
On the grass when I arrive,
This line has a definite, quick, springy rhythm, with  consonant  words ‘picky’ and ‘nervy’ describing the bird’s rapid, lively movements to find food. The ‘goldbeak’ suggests value and riches; not surprisingly as it is the beak that  swoops and captures the worms and grubs. Note that ‘goldbeak’ is half-rhyming with ‘talkback’ and ‘comeback’.
