Ovenbird: A singer everyone has heard

There is a singer everyone has heard,

Loud, a mid-summer and a mid-wood bird,

Who makes the solid tree trunks sound again

--Robert Frost

Even if you do not know the Ovenbird, you know the distinct, emphatic song of this little warbler: Tea-Cherr, Tea-Cherr, Tea-Cherr. Teacher teacher teacher is the mnemonic, so I think of it as my bird.
