This valiant little warrior possesses the faculty of imitating the notes
of other birds, especially such as are indicative of pain. Thus it will of-
ten mimic the cries of Sparrows and other small birds, so as to make you
believe you hear them screaming in the claws of a Hawk ; and I strongly
suspect this is done for the purpose of inducing others to come out from
their coverts to the rescue of their suffering brethren. On several occa-
sions I have seen it in the act of screaming in this manner, when it would
suddenly dart from its perch into a thicket, from which there would im-
mediately issue the real cries of a bird on which it had seized. On the
banks of the Mississippi, I saw one which for several days in succession
had regularly taken its stand on the top of a tall tree, where it from time
to time imitated the cries of the Swamp and Song Sparrows, and shortly
afterwards would pitch downwards like a Hawk, with is wings close to
its body, seldom failing in obtaining the object of its pursuit, which it
would sometimes follow even through the briars and brambles among
which it had sought refuge. When unable to secure the prey, it would
reascend to its perch, and emit loud and discordant notes of anger.
Whenever I could see it strike its victim, it appeared to alight on its
back, and instantly strike its head, which on such occasions I have several
times found torn open. If not disturbed, the Shrike would then tear up
the body, and swallow in large pieces, not well cleared of the feathers,
every part excepting the wings. It now and then pursues birds that are
on the wing to a considerable distance. Thus, I saw one follow a Turtle
Dove, which, on being nearly caught, pitched on the ground, where its
skull was bruised in a moment ; but the next instant both birds were in
my possession.
The courage, activity, and perseverance of this species, are quite surprising. In winter, when insects are scarce, and small birds rare in the Eastern States, I have known it to enter the cities and attack birds in cages. During my stay at Boston, several of them were brought to me, that had been caught in the apartments in which cages containing canaries were kept, and in every instance after the little favourite had been massacred. Near the same city I observed an individual poised on wing, in the manner of our Sparrow Hawk, for several minutes at a time, over the withered grass and sedges of salt water meadows, when it suddenly pounced on some small bird concealed there.
Although its feet are small and apparently weak, its claws are sharp, and it is capable of inflicting a pretty severe wound on the finger or hand.
