t he
destroys are mostly seed-eaters--not the most valuable kinds to the
farmer.

"In fact, the Shrike is especially useful in helping us to drive out the
greedy, quarrelsome English Sparrow. This disreputable tramp not only
does no work for his taxes--he hates honest work, like all vagrants
--but destroys the buds of trees and plants, devours our grain crops,
and drives away the industrious native birds who are good Citizens; so
the Wise Men, who have tried the Sparrow's case, say that he is a very
bad bird, who ought to suffer the extreme penalty of the law.

"For this reason we must forgive the Shrike if he takes a few other
birds when he is hungry and in a hurry. He has a strange habit which has
earned for him the name of Butcher Bird. If at any time he secures more
food than he needs for his immediate use, he puts it by to keep in 'cold
storage' by hanging it on the frozen twigs of a tree or thorn bush.
Heart of Nature has doubtless taught him this habit through hard
experience. Where the Shrike spends his winters, the food-supply is
variable; it may snow for days and days, when he can find nothing to
eat; so he has learned to store up provisions when the hunting is good,
and of course such a thrifty bird may sometimes save up more than he
really needs.

"You may know this Shrike on sight without hearing him sing--and perhaps
you do not expect a cannibal bird to be a singer. But in late March and
early April, when he is about to take his homeward journey to the North,
he often warbles beautifully, and even brings in some mocking notes,
until you would think that a Catbird, Thrasher, or Mockingbird must have
wandered from the South too soon; and if you ever happen to see a Shrike
and a Mocker close together, you may mistake one for the other, they
look so much alike at a little distance."

"I never knew that there were nice birds around in winter," said Nat. "I
thought all the country was good for then, was for coasting and skating!
I wish I could stay here a whole year, Uncle Roy."

"Stranger things have happened," said the Doctor, looking at Olive with
a twinkle in his eye that the children did not see.
