Birds
The SHRIKES (_Lanii_) are a very numerous and well-known group, equally
common in all parts of the world. In these birds the body is powerful
and the breast prominent; their neck is strong, the head comparatively
large and round, the wings broad and rounded, the third or fourth quill
far exceeding the rest in length, while their tail is long and graduated.
The beak is powerful, compressed at its sides, and terminates in a strong
hook, near which the upper mandible has a very perceptible tooth-like
appendage. The feet are large and robust, the toes long, and armed with
sharp claws; the plumage is rich, thick, and lax, and its coloration
pleasing and varied.
Woods surrounded by meadows or pasture lands are the favourite resorts
of these birds; but they are also constantly found dwelling in hedges,
among brushwood, or upon solitary trees. Such species as frequent
northern latitudes migrate regularly during the autumn, and find their
way, in pursuit of food, even to Central Africa. In their habits they
closely resemble some of the birds of prey, and their movements bear
considerable similarity to those of the Raven family. Although by no
means conspicuously endowed in most respects, the voice in some species
is highly developed, and all seem capable of improving their natural
powers of song, by imitating the sounds produced by other birds. Their
flight is irregular, and their step upon the ground a mere series of
hops; but, despite these deficiencies, they display great dexterity in
securing their prey, even should it equal themselves in size; and are
exceeded by no other members of the feathered creation in rapacity and
the cruelty which they display towards their victims. They devour insects
in large quantities, but by no means rely solely upon them for food, for
they destroy great numbers of Sparrows and other small birds; and their
attacks are all the more dangerous as they are entirely unsuspected. It
is not uncommon to see a large party of little birds quietly perched
around a Shrike, and evidently regarding it as a friendly companion,
whilst in reality the treacherous intruder is merely watching for a
favourable moment to dart upon and kill some member of the group that it
has already singled out as its prey. One very remarkable habit, depicted
in the engraving on page 145, is highly characteristic of this family; we
allude to the practice of spiking their victims upon sharp thorns, from
which circumstance they have obtained the well-merited appellation of
BUTCHER BIRDS. The nest of the Shrike is artistically constructed of the
green portions of plants, and placed in a thick bush or closely-foliaged
branch. The brood consists of from four to six eggs, which are hatched by
the female alone, whilst her mate undertakes the duty of providing for
her nourishment. Both parents assist in feeding the nestlings, and in
defending them. The young remain under parental care and instruction for
