Why is the cuckoo's melody preferred
And nightingale's rich song so fondly praised
In poet's rhymes? Is there no other bird
Of nature's minstrelsy that oft hath raised
One's heart to extacy and mirth as well?
I judge not how another's taste is caught:
With mine, there's other birds that bear the bell
Whose song hath crowds of happy memories brought.
Such the wood-robin singing in the dell
This could represent the poet’s modesty. 
 The idea that ‘taste’ can be ‘caught’ is neat and concise.
