- Name the species.
- List the species for whom walking along
raised linear objects is habitual. - Speculate about the possible reasons
for this behavior.

The true nature of this handsome,
inoffensive-looking songbird is
suggested by the hook on the tip of its
beak. Sometimes called "butcher bird",
it has adapted to living on smaller birds
as well small mammals and larger
insects, which it may impale on a thorn
for later consumption.
Normally a denizen of the North, it
often filters southward in winter, where
it may frequent the vicinity of bird
feeders
A prime example of imitative
plumage, it has assumed the look of a
mockingbird and even can sing a poor
imitation of one, all by way of lulling
unwary prey.
Typical of birds from the far North,
it is easily approached, seeming not to
recognize humans as potential
enemies.
