After the foregoing study was written, Mr. Frederic A. Ober kindly placed at my disposal his unpublished notes upon another solitaire, the _siffleur montagne_, or mountain whistler. He had the bird in confinement for some time, while in the Antilles on a collecting tour for the United States National Museum; and the bird's character, as shown in captivity, so closely resembled the one I have tried to depict, that I give it as evidence that others have similarly interpreted the manners of the family. [Sidenote: _LOVE OF SOLITUDE._] To begin with his love of solitude, one of the strongest characteristics of the _Myadestes_ wherever found. It is that more than anything else which, in connection with his wonderful song, has wrapped the bird in mystery, and aroused the superstitions of the natives of the countries in which he lives. Mr. Ober says, and every one of the few observers who have succeeded in seeing the bird confirms the statement, that he is found only in the most solitary places, inaccessible mountains, wild, gloomy ravines, and dark, impenetrable gorges. Here the graceful bird delights to dwell, calling and singing from his post on a branch overhanging the perpendicular cliffs, hundreds of feet above the level earth. One of them, indeed, secures his beloved solitude by inhabiting the craters of extinct volcanoes. In sprightliness of manner this bird of solitude reminds one of the catbird, whom he also greatly resembles in looks. He has the quick-darting movements of the flycatchers, and at the same time a strange, preoccupied air, that seems to make him oblivious of people, although they may be within a few feet of him. Passing one of these peculiarly lonely places one day in his wanderings, Mr. Ober heard the note of the siffleur close at hand. He crept cautiously through the trees until he saw the bird, who had ceased singing, and was eating berries from a tall shrub, clinging to its hanging branches. He soon finished his repast, flew to a dead branch, plumed his feathers, and after a few moments resumed his singing. He uttered a few trills of a rare musical quality that held his listener spellbound, then lightly flew to another branch overhanging the little ravine, at the bottom of which a babbling brook made music,--"not so liquid as siffleurs,"--says the historian. Here a few more strains fell from him, then he flitted to a swinging vine, repeated his bewitching note, and in a moment disappeared. The tones, says Mr. Ober, "are thrilling with solemn music and indescribably impressive." They have also a ventriloquial quality, and many tunes had he vainly searched for the singer, until a note of another sort betrayed his position, which was sometimes almost over the observer's head.
