yet that dainty casket with its complement of speckled eggs! The nest was so placed that it had for canopy a large, broad, drooping leaf of yellow dock. This formed a perfect shield against both sun and rain, while it served to conceal it from any curious eyes from above,—from the cat, for instance, prowling along the top of the wall. Before the eggs had hatched the docken leaf wilted and dried and fell down upon the nest. But the mother bird managed to insinuate herself beneath it, and went on with her brooding all the same.
Then I arranged an artificial cover of leaves and branches which shielded her charge till they had flown away. A mere trifle was this little bob-tailed bird with her arts and her secrets, and the male with his song, and yet the pair gave a touch of something to those days and to that place which I would not willingly have missed.
I have spoken of nature as a stage whereon the play, more or less interrupted and indirect, constantly goes on. One amusing actor upon that stage one season, upon my own premises, was a certain male bluebird. To the spectator it was a comedy, but to the actor himself I imagine it was quite serious business. The bird and his mate had a nest in a box upon an outhouse. In this outhouse was a window with one pane broken out. At almost any hour in the day from spring to early summer, the male bird could be seen fluttering and pecking against this window from the outside. Did he want to get within? Apparently so, and yet he would now and
then pause in his demonstrations, alight in the frame of the broken pane, look intently within, and after a moment resume his assault upon the window. The people who saw the actions of the bird were at a loss how to interpret them. But I could see at once what was the matter. The bird saw its image in the mirror of the glass (the dark interior helped the reflection) and was making war, as he supposed, upon a rival. Only the unyielding glass kept him from tweaking out every saucy blue feather upon the spot! Then he would peep in through the vacant pane and try to determine where his rival had so suddenly disappeared. How it must have puzzled his little poll! And he learned nothing from experience. Hundreds of times did he perch in the broken pane and sharply eye the interior. And for two months there did not seem to be an hour when he was not assaulting the window. He never lost faith in the reality of the bird within, and he never abated one jot his enmity toward him. If the glass had been a rough surface he would certainly have worn his beak and claws and wings to mere stubs. The incident shows the pugnacious disposition of the bluebird, and it shows how shallow a bird's wit is when new problems or conditions confront it. I have known a cock-robin to assault an imaginary rival in a garret window, in the same manner, and keep up the warfare for weeks.
On still another occasion similar antics of a male bluebird greatly disturbed the sleep of my hired man in the early morning. The bird with its mate had
a nest in a box near by the house, and after the manner of the bluebirds was very inquisitive and saucy about windows; one morning it chanced to discover its reflected image in the windows of the hired man's room. The shade, of some dark stuff, was down on the inside, which aided in making a kind of looking-glass of the window. Instantly the bird began an assault upon his supposed rival in the window, and made such a clattering that there was no more sleep inside that room. Morning after morning the bird kept this up till the tired plowman complained bitterly and declared his intention to kill the bird. In an unlucky moment—unlucky for me, who had morning work to be done—I suggested that he leave the shade up and try the effect. He did so, and his morning sleep was thenceforth undisturbed.
A Western correspondent writes me that she once put a looking-glass down on the floor in front of the canary bird's cage. The poor canary had not had any communion with his own kind for years. "He used often to watch the ugly sparrows—the little plebeians—from his aristocratic gilded palace. I opened his cage and he walked up to the looking-glass, and it was not long before he made up his mind. He collected dead leaves, twigs, bits of paper, and all sorts of stray bits, and began a nest right off. Several days after in his lonely cage he would take bits of straw and arrange them when they were given him."
