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 shewing 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. — Ed.]

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 coun- 
try was attracted to the circumstance, by the different opinions entertained by 
Mr James Wilson, and Mr Selby. The latter gentleman has long since satis- 
factorily proved their indentity from observation, and the numerous specimens
