BIRDS IN A VILLAGE 91
after three days it all at once struck me that no fowl could lay an egg about every ten or twelve minutes, and go on at this rate day after day, and, getting up, I went out to look for the cackler. A few hens were moving quietly about the open ground surrounding the cottage where the sound came from, but I heard nothing. By and by, when I was back in my room, the cackling sounded again, but when I got out the sound had ceased and the fowls, as before, appeared quite unexcited. The only way to solve the mystery was to stand there, out of doors, for ten minutes, and before that time was over a starling with a white grub in his beak, flew down and perched on the low garden wall of the cottage, then, with some difficulty, squeezed himself through a small opening into a cavity under a strip of zinc which covered the bricks of the wall. It was a queer place for a starling's nest, on a wall three feet high and within two yards of the cottage door which stood open all day. Having delivered the grub, the starling came out again and, hopping on to the zinc, opened his beak and cackled like a hen, then flew away for more grubs.
I observed the starling a good deal after this,

and found that invariably on leaving the nest, he uttered his imitation of a fowl cackling, and no other note or sound of any kind. It was as if he was not merely imitating a sound, but had seen a fowl leaving the nest and then cackling, and mimicked the whole proceeding, and had kept up the habit after the young were hatched.
To return to my experience on the common. About fifty yards from the spot where I was there was a dense thicket of furze and thorn, with a huge mound in the middle composed of a tangle of whitethorn and bramble bushes mixed with ivy and clematis. From this spot, at intervals of half a minute or so, there issued the call of a duck--the prolonged, hoarse call of a drake, two or three times repeated, evidently emitted in distress. I conjectured that it came from one of a small flock of ducks belonging to a cottage near the edge of the common on that side. The flock, as I had seen, was accustomed to go some distance from home, and I supposed that one of them, a drake, had got into that brambly thicket and could not make his way out. For half an hour I heard the calls without paying much attention, absorbed in watching the quaint little
