[Illustration: GREAT GREY SHRIKE, OR BUTCHER BIRD, WITH ITS VICTIMS--SHREWS AND BLUE TITMOUSE.]
Let us go on the moors again, and watch the coots and water-hens in the reedy pools near the aqueduct. Do you see that great tit on a branch of this poplar? He is actually at work doing a bit of butchery on a small warbler. See how he is beating the poor little fellow on the head; he wants to get at his brains. "Are there not birds called butcher-birds?" asked Willy, "that fix their victims on thorns, and then peck off their flesh? Shall we see any of them?" There are three kinds of butcher-birds that have been known to come to this country. Two kinds are very uncommon, and we are not likely to meet with any of them in our walks. I may as well, however, tell you something about them; but, as I have no personal knowledge of the habits of any of the species, I must get my information from other sources. The great grey shrike, the red-backed shrike, and the woodchat shrike, are the three species of the family occurring in Great Britain; the red-backed shrike is the only tolerably common one, arriving in this country late in April, and quitting it in September. Mr. John Shaw tells me this bird visits the quarry grounds at Shrewsbury every spring, and an early riser, if he goes there, can see these birds readily. Mr. Yarrell says that the great grey shrike is only an occasional visitor to this country, and is generally obtained between autumn and spring. Its food consists of mice, shrews, small birds, frogs, lizards, and large insects. "After having killed its prey, it fixes the body in a forked branch, or upon a sharp thorn, the more readily to pull off small pieces from it." The following remarks are by a gentleman who had one of these birds in confinement:--"An old bird of this species," he says, "taken near Norwich in October, 1835, lived in my possession twelve months. It became very tame, and would readily take its food from my hands. When a bird was given it, it invariably broke the skull, and generally ate the head first. It sometimes held the bird in its claws, and pulled it to pieces in the manner of hawks, but seemed to prefer forcing part of it through the wires, then pulling at it. It always hung what it could not eat up on the sides of the cage. It would often eat three small birds in a day. In the spring it was very noisy, one of its notes a little resembling the cry of the kestrel." It is a cunning as well as a bold bird. It is said that by imitating the notes of some of the smaller birds it calls them near it, and then pounces upon some deluded victim. The shrike is used by falconers abroad for trapping falcons; "it is fastened to the ground, and by screaming loudly gives notice to the falconer, who is concealed, of the approach of a hawk." You will notice in any picture of a shrike how admirably adapted is its curved beak for butchering purposes. The red-backed shrike "frequents the sides of woods and high hedgerows, generally in pairs, and may frequently be seen perched on the uppermost branch of an isolated bush, on the look out for prey. The males occasionally make a chirping noise, not unlike the note of the sparrow." It also imitates the voice of small birds. Mr. Yarrell says "the food of the red-backed shrike is mice, and probably shrews, small birds, and various insects, particularly the common May-chaffer. Its inclination to attack and its power to destroy little birds has been doubted; but it has been seen to kill a bird as large as a finch, and is not unfrequently caught in the clap-nets of London bird-catchers, having struck at their decoy-birds;" and Mr. Hewitson says--"Seeing a red-backed shrike busy in a hedge, I found, upon approaching it, a small bird, upon which it had been operating, firmly fixed upon a blunt thorn; its head was torn off, and the body entirely plucked."
