308 RING-TAILED EAGLE. 



arrival early in April, the black feathers on the crown are 

 frequently seen coming out, intermixed with the former ash- 

 coloured ones. 



This species has all the agility and many of the habits of 

 the flycatcher. 



[Parts VII. and VIII. of this work, commencing "with the next 

 description (ring-tailed eagle), seem to have been finished more 

 hurriedly, and contain greater mistakes in the nomenclature, than any 

 of the preceding ones ; the descriptions, however, are alike vivid and 

 well drawn. In 1824 Mr Ord, the personal friend of Wilson, undertook, 

 at the request of the publisher, to improve these two parts, and they 

 were accordingly republished with that gentleman's additions. We have 

 thought it better to print from the original edition, as showing the true 

 opinions of its author, but have occasionally inserted, at the conclusion 

 of the descriptions, the observations of Mr Ord, taken from his reprint.

The reader is now presented with a portrait of this cele- 

 brated eagle, drawn from a fine specimen shot in the county 

 of Montgomery, Pennsylvania. The figure here given, though 



* Wilson, like many other ornithologists, imagined that the ring-tailed 

 and golden eagles constituted two species. Temminck, I believe, first 

 asserted the fact of their being identical, and the attention of naturalists 

 in this country was attracted to the circumstance by the different 

 opinions entertained by Mr James Wilson and Mr Selby. The latter 

 gentleman has long since satisfactorily proved their identity from obser- 

 vation, and the numerous specimens kept alive in various parts of Britain 

 have set the question completely at rest. The ring-tail is the young of
