"Not very abundant, but seems to be well distributed over the 

 island. It has all the cliaracteristics of tlie true Mocking-Bird 

 {Mimus polyglottus) in its habits. Of solitary disposition, it 

 attacks every bird of its own species that approaches its usual 

 haunts. There was one that took up its quarters in our camp, 

 and was certainly the tamest bird of this genus I ever saw. He 

 appeared to take pleasure in our society, and attacked furiously 

 every bird that came near us ; he doubtless regarded us as his 

 •own property, often perching upon the table when we were 

 taking our meals, and eating from our hands, as though he liad 

 been brought up to this kind of treatment; at times ascending 

 to the branches over our heads,' he would break forth into loud 

 and mellow song, very thrush-like. In the still hours of the 

 night, while roosting on the branches near us, he would some- 

 times utter a few dreamy notes, recalling to mind the well- 

 ,known habits of the true Mocking-Bird."
