This satirical poem is about the male nightingale and how the males sang and were mistaken for females. Read about it here (there's only a small mention of it). Yeah, I had to research too, Ponz.
The Nightingale's Frustration
How could you mistake me for a lady?
My trills and curdles are quite masculine
Beauty and passion can be manly
But the night songstress, you all name me
I'm hunting for company in this twilight
For company of a lady, not a man!
Just because I'm still going, and it's now daylight
Does not mean I'm a lady...
I'm just not a pretty sight
Go ahead, laugh at my misfortune
But please, don't mistake my gender
The truth has been effected by distortion
When will this dreadful nightmare end?
Years have passed, technology advanced
Now my time has come
My old title will be abolished
Night songstress forgotten once and for all
Humans will distinguish me from a woman
The world will see the light
So trill I will, with pride and passion
Here I go with all my might!
