It may be remarked that by autumn the young missel-thrushes would not only fly well, but would have been educated by the old birds, and would have come to maturity. Their natural independence might then come into play. But these are effects rather than causes, besides which I think birds and animals often act from custom rather than for advantage. Among men customs survive for centuries after the original meaning has been lost. I had always been told by country people that the missel-thrush was a solitary bird, and when I first observed a pack and mentioned it some incredulity was expressed. Very naturally in summer people do not see much but hay and wheat. It was noticed on the farms about the Chace in the springs of 1878 and 1879 that the corncrakes, which had formerly been so numerous and proclaimed their presence so loudly, were scarcely heard at all. It is a little outside my subject, since it did not occur in the Chace, but the other day a friend was telling me how he had been hunted by bucks while riding a bicycle. He was passing through a forest in the summer, when he suddenly became aware of six or seven bucks coming down a glade after him. The track being rough he could not ride at full speed--probably they would have outstripped him even if he had been able to do so--and they were overtaking him rapidly. As they came up he saw that they meant mischief, and fearing a bad fall he alighted by a tree, behind which he thought to dodge them. But no sooner did he touch the ground than the bucks so furiously rushing after him stopped dead in their career; he stepped towards them, and directly they saw him walking they retreated hastily to a distance. The first berries to go as the autumn approaches are those of the mountain-ash. Both blackbirds and thrushes began to devour the pale-red bunches hanging on the mountain-ashes as early as the 4th of September last year. Starlings are fond of elder-berries: a flock alighting on a bush black with ripe berries will clear the bunches in a very short time. Haws, or peggles, which often quite cover the hawthorn bushes, are not so general a food as the fruit of the briar. Hips are preferred; at least, the fruit of the briar is the first of the two to disappear. The hip is pecked open (by thrushes, redwings, and blackbirds) at the tip, the seeds extracted, and the part where it is attached to the stalk left, just as if the contents had been sucked out. Greenfinches, too, will eat hips.
