Bees, dolphins, rays of sunlight, snow, starlings, doves, frogs, a bull, falcons, fishes, larks, and rooks are all used, generally with characteristic touches of detail.
Specially tender is this:
E'en as the bird, who 'mid the leafy bower
Has, in her nest, sat darkling through the night
With her sweet brood; impatient to descry
Their wished looks, and to bring home their food,
In the fond quest, unconscious of her toil;
She, of the time prevenient, on the spray
That overhangs their couch, with wakeful gaze
Expects the sun, nor, ever, till the dawn
