Guardian Angle  (spelling intentional)
 
The little bird nests in the traffic light sign
hanging in the air from the black power line
cats can’t get her there, and squirrels won’t climb
out where the traffic rushes all the time

Above the cars she bobs and weaves
building her shelter with twigs and leaves
it’s a clever thing for a bird to do
with no papa bird to help her thru

The eggs are lit by red and green
and the yellow light that’s in between
throughout the season she does her best
to warm and guard her orphaned nest

And when it’s time for them all to leave
in the empty nest, little bird will grieve
for if their first flight isn’t met by luck
they’ll be baby bird jam on the wheels of a truck

c. 1988, B. Riley
