Early robins

Early robins are a signal of persistence. Perhaps this is why I like them so much.

Robins are seen
As common birds
Still
They are a sign
Of spring
As much as forsythia
As much
As pussy willows.
This year I watch them
Listen for worms
Listen
And fail to find them
Yet.
Perhaps they came back
Too early
I will continue
To watch
Any minute now
Worms will surface
Robins will then know
It is time
To nest.
