The Return of the Robins

Walking down the street, it is a chilly spring day...
The Robin is seen in mid March.
The first one of the season---
I've seen them nigh a February's fay---
And the strongest males return
From their Southern homes, and they pioneer
Their troop, searching out to see if the land is safe.
And then, their little ones, their females
And their weaker males return.
Yet, only the strongest are the pioneers, whom
You see are those first males of the season.
The Maples have their florets, and the Willows
Are soon to push forth their yellow branches---
In fact, some already have.
