Migrate north from long grass parkland
To haze in urinary tracts of
Pubic toilet

In unsteady patterns
Uncertain their limbs
Coordination a clumsy flock

When for some delirium
On their minds, raptures start
To think for them; symbiotic tremors

Omnivorous perhaps ?

Feeding from bins
Or erupts from the penny
Fountain biting through the
Neck of a swan
