JUST out of hearing of the grasshopper warblers, there was a good-sized pool of water on the common, probably an old gravel-pit, its bottom now overgrown with rushes. A sedge warbler, the only one on the common, lived in the masses of bramble and gorse on its banks; and birds of so many kinds came to it to drink and bathe that the pool became a favourite spot with me. One evening, just before sunset, as I lingered near it, a pied wagtail darted out of some low scrub at my feet and fluttered, as if wounded, over the turf for a space of ten or twelve yards before flying away. Not many minutes after seeing the wagtail, a reed-bunting--a bird which I had not previously observed on the common--flew down and alighted on a bush a few yards from me, holding a white crescent-shaped grub in its beak.

I went up softly to the spot, when out sprang the old bird I had seen, but only to drop to the ground just as the wagtail had done, to beat the turf with its wings, then to lie gasping for breath, then to flutter on a little further, until at last it rose up and flew to a bush.
After admiring the reed-bunting's action, I turned to the dwarf bush near my feet, and saw, perched on a twig in its centre, a solitary young bird, fully fledged but not yet capable of sustained flight. He did not recognise an enemy in me; on the contrary, when I approached my hand to him, he opened his yellow mouth wide, in expectation of being fed, although his throat was crammed with caterpillars, and the white crescent-shaped larva I had seen in the parent's bill was still lying in his mouth unswallowed. The wonder is that when a young bird had been stuffed with food to such an extent just before sleeping time,
