A call-note, and in its breeding-haunts a sweet, warbling song.
In common with all winter birds, its movements are guided by the food supply, and if severe cold and heavy snows drive away the small birds, and bury the mice upon which it feeds, the Shrike must necessarily rove.
Grasshoppers, beetles, other large insects, and field-mice are staple articles of its food in seasons when they are obtainable; in fact, next to insects, mice constitute the staple article of its diet; and protection should be accorded it on this account, even though we know the Shrike chiefly as the killer of small birds. The victims are caught by two methods: sneaking,—after the fashion of Crows,—and dropping upon them suddenly from a height, like the small Hawks. In the former case the Shrikes frequent clumps of bushes, either in open meadows or gardens, lure the little birds by imitating their call-notes, and then seize them as soon as they come within range. They often kill many more birds than they can possibly eat at a meal, and hang them on the spikes of a thorn or on the hooks of a cat-brier in some convenient spot, until they are needed, in the same manner as a butcher hangs his meat; and from this trait the name “Butcher-bird” was given them.
During some of these wintry days of meeting, questions and answers about the birds seen filled the time, and then Gray Lady read to them from some of her many books what people living in other places had said and thought of these same familiar birds. Besides the stories, she told them many things about the building of a bird, its bones, its feathers, the reasons why of the various kinds of feet and bills, the grouping of race, tribe, and family that both divide the bird world and at the same time bind it together; for she very well knew that when spring came with its procession of songsters, the children would be so eager to listen, see, follow, and learn the names of the living birds that they would not have patience to listen to the dry details.
THE SNOWBIRD
When the leaves are shed
And the branches bare,
When the snows are deep
And the flowers asleep,
