Not observed by any of the Kxpeditious. ** 7 



With a range somewhat corresponding to that oi E. calendula, and y "^ 

 nearly as extensive, this species is rather more northerly. Thus, it^ii'' 

 winters abundantly in the Middle States, and even as far north as Mas- ^S'X. 

 sachusetts, on the Atlantic side; while oil the Pacific it occurs at thej,^. 

 same season at least as high as VVashiugtou Territory. Its winter range ^*. 

 extends to our southern borders, and into Mexico, but not, so far as we'^AT " 

 now know, to Central Ameriea. Similarly, nothing is known with cer-/ f'^' 

 tainty of its breeding anywhere in the United States, though it proba- / ^^ 

 bly will be found to do so in mountainous regions toward our northern ^^.^ 

 border. It has been found nesting in Newfoundland by Audubon, and 7/ / " 

 in Labrador, according to Baedecker, who notices the egg, as above; J"//, 

 • but I have never myself seen an authentic specimen. f/l - . 



At a very early age the crown is perfectly plain, but it soon shows the 

 golden of both sexes, aud subsequently the flame-color of the male^ 

 There appears to be little probability that B. cuvieri will be established 

 as a species, and nothing to show that the true E. cristatus of E-irope 

 occurs in this country, though it is so given by ISTuttall.
