The days are shortening
as they should, going forward
on their slow march from equilibrium.
The birds arrive and leave
as they should, caring nothing
for clocks or calendars, merely
reading the sky and weather.
They know their world
is changing, hotter days
and nights and the storms
they must outfly growing
ever stronger, more dangerous.
They know that we are the cause,
our greed, our arrogance,
and they know that one day
it is we who will be remembered
for our self-created extinction.
