There's most likely a pe(e/a)k before fall

I heard a Stock-dove sing or say
His homely tale, this very day;
His voice was buried among trees,
Yet to be come at by the breeze:
He did not cease; but cooed--and cooed:
And somewhat pensively he wooed:
He sang of love, with quiet blending,
Slow to begin, and never ending;
Of serious faith, and inward glee;
That was the song,--the song for me!
