To study a bird so shy required extraordinary precautions; I therefore sought, and found, a post of observation a long way off, where I could look through a natural vista among the shrubs, and with my glass bring the bush and its precious contents into view. For greater seclusion in my retreat, so that I should be as little conspicuous as possible, I drew down a branch of the low tree over my seat, and fastened it with a fine string to a stout weed below. Then I thought I had a perfect screen; I devoutly hoped the birds would not notice me.
Vain delusion! and labor as vain! Doubtless two pairs of anxious eyes watched from some neighboring bush all my careful preparations, and then and there two despairing hearts bade farewell to their lovely little home, abandoned it and its treasures to the spy and the destroyer, which in their eyes I seemed to be.
This conclusion was forced upon me by the experiences of the next few days. The birds absolutely would not approach the nest while I was in the park. The first morning I sat motionless for nearly two hours, and not a feather showed itself near that bush; it was plainly "tabooed." During the next day the chat called from this side and that, moving about in his wonderful way, without disturbing a twig, rustling a leaf, or flitting a wing—as silently, indeed, as if he were a spirit unclothed.
While waiting for him to show himself, making myself as nearly a part of nature about me as a mortal is gifted to do, I congratulated myself upon the one good look I had secured, for, with all my efforts and all my watching, I saw him but twice more all summer. The enigma of that remarkable voice would have been maddening indeed, if I could not have known to whom it belonged.
After several days of untiring observation I had but two glimpses to record. On one occasion a chat alighted on the top sprig of the fateful shrub, as if going to the nest, but almost on the instant vanished. The same day, a little later, one of these birds flitted into my view, without a sound. So perfectly silent were his movements that I should not have seen him if he had not come directly before my eyes. He, or she, for the pair are alike, alighted in a low bush and scrambled about as if in search of insects, climbing, not hopping. He stayed but a few seconds and departed like a shadow, as he had come.
On the tenth day after my discovery of the nest with its trio of eggs I went out as usual, for I could not abandon hope. In passing the nest I glanced in and saw one egg; I could never see but one as I went by, but, not liking to go too near, I presumed that the other two were there, as I had always found them, and slipped quietly into my usual place.
In a few moments the chat shouted a call so near that it fairly startled me. From that he went on to make his ordinary protest, but, as happened nearly every time, I was not able to see him. I saw something—something that took my breath away. A shadowy form creeping stealthily through the shrubs five or six feet from me. It glided across the opening in front, and in a moment went to the bush I was watching. In silence, but with evident excitement, it moved about, approached the nest, and in a few seconds flew quickly across the path in plain sight, holding in its mouth something white which was large for its beak. I was reminded of an English sparrow carrying a piece of bread as big as his head, a sight familiar to every one. In a minute or two the same bird, or his twin, came to the nest again and disappeared on the other side.
When I left my place to go home, I looked with misgivings into the nest on which I had built so many hopes. Lo! it was empty!
Now I identified that stealthy visitor absolutely, but I shall never name him. I have never heard him accused of nest-robbing, and I shall not make the charge; for I am convinced that the chat had deserted the nest, and that this abstracter of eggs knew it, and simply took the good things the gods threw in his way—as would the best of us.
After that unfortunate ending the chat disappeared from the little park; but a week later I came upon him, or his voice, in a private and rarely visited pasture down the road, where many clumps of small trees and much low growth offered desirable nesting-places. He made his usual protest, and feeling that I had been the cause of the tragedy of the first nest, though I had grieved over it as much as the owners could, the least I could do, to show my regret, was to take myself and my curiosity out of his neighborhood. So I retired at once, and left the whole broad pasture to the incorrigible chat family, who, I hope, succeeded at last in enriching the world by half a dozen more of their bewitching kind.
