Love Songs of the Winter Wrens

Phylogenists say it’s encoded into the genes
Whether an individual has a repertoire of six songs or sixty.
Some learn by imitation or a kind of cultural evolution.
In others, the songs are uniquely created, part of their DNA,
The seed of the tune, planted before they were hatched,
Lying dormant until the gentle, warm touch of the springtime sun
Coaxes it awake to fill to bursting the lungs of the waiting wren.
There are many unanswered questions.
The Japanese Wrens sing fewer songs.
Do they lack the imagination of those that live in the West?
What selective advantage does the wider repertoire convey?
On the basis of song there seems to be a close affinity.
What evolutionary relationships might the wrens’ songs reveal?
