Attempting to understand evolution

If I think that I -

I’m at the top of Creation,

I’d be ignoring something:

the thin legs of birds:

thinner than matchsticks,

but strong enough,

precisely strong enough

to support the fragile flesh,

the open wings,

sharp eyes, sharp beak.

And so from the long high branch

of the tree outside the bathroom

a finch is staring at me,

it stands on its thin legs,

silent, still, at ease,

until without warning

it opens its sharp little beak

and starts to sing, sing from the heart.
