Notes
May Fourth
By this time one of your bird houses should be tenanted by a pair of house wrens. They migrate at night and the male arrives about a week in advance of his mate. Both birds assist in building the nest and in raising the young. As soon as the first brood has been reared, the lining of the nest is removed, and a new one built before the second set of six eggs is laid. Wrens may easily be tamed to take spiders and caterpillars (not the hairy ones) from the end of a stick and even from one's hand.
May Fifth
How much easier would be the work of nest building if we provided the birds with nesting material. Scatter strips of cloth, and pieces of coarse twine on the ground for the robins; hair from the tail and mane of horses for the chipping sparrows and wrens; twine and horse-hair for the orioles; bits of "waste" for the yellow warblers, and grapevine bark for the catbirds. None of these strands should be more than four inches long.
May Sixth
In some localities the shad-tree is now in full blossom. As you pause to cut off a few twigs, your ears are greeted by a never ceasing chorus of toad music. This is the toad's "love song"—a high-pitched, somewhat tremulous, and rather monotonous note.
