One of his own family, another siffleur, being added to the imprisoned party, the first-comer was most unfriendly, flying at him, and trying to keep him from food and water. Another indication of the bird's love of quiet was his annoyance at the hummingbirds, whose ways Mr. Ober was studying, and who flitted about the room all the time. From the first he regarded them with disfavor. Their frivolous manners and their constant humming were not pleasing to him; but when they became so impertinent as to alight on his back, this trifling with his dignity was past endurance; he hissed, and snapped his beak at the elusive little creatures, and finally worked himself into such a rage that he was found completely exhausted, and almost in a dying condition. These continued excitements, indeed, so wore upon his sensitive nature that he did not long survive his extreme passion. This was the more to be regretted because of the readiness with which he accepted his fate. He became tame in a week after capture, and readily took food from the fingers. From the first he never made the least effort to escape, but seemed perfectly contented, so long as he was alone. It was the presence of intruders--as he regarded them--that he resented so fatally. One of this most interesting family, Townsend's fly-catching thrush (_Myadestes Townsendii_) is resident in the mountains of Colorado, and it is pleasing to see how the most scientific and the least emotional of chroniclers fall into rapture over his song. "Never have I heard a more delightful chorus of bird music," says one. "The song can be compared to nothing uttered by any other bird I have heard," says another. "A most exquisite song in which the notes of purple finch, wood thrush, and winter wren are blended into a silvery cascade of melody that ripples and dances down the mountain-side as clear and sparkling as the mountain brook," says a third. Charles Dudley Warner, who found the clarin a favorite cage bird in Mexico, says of his song (in "Mexican Notes"): "Its long, liquid, full-throated note is more sweet and thrilling than any other bird note I have ever heard; it is hardly a song, but a flood of melody, elevating, inspiring as the skylark, but with a touch of the tender melancholy of the nightingale in the night."
