From Britannia's Pastorals: Birds in May

As (woo'd by May's delights) I have been borne
To take the kind air of a wistful morn
Near Tavy's voiceful stream (to whom I owe
More strains than from my pipe can ever flow),
Here have I heard a sweet bird never lin
To chide the river for his clam'rous din;
There seem'd another in his song to tell,
That what the fair stream did he liked well;
And going further heard another too,
All varying still in what the others do;
A little thence, a fourth with little pain
Conn'd all their lessons, and them sung again;
So numberless the songsters are that sing
In the sweet groves of the too-careless spring,
That I no sooner could the hearing lose
Of one of them, but straight another rose,
And perching deftly on a quaking spray,
Nigh tir'd herself to make her hearer stay.
. . . . .
Shrill as a thrush upon a morn of May.
