"Tbechestnut about the head 111 adult males varies In amount with the Individual; 

 Bometlmos (as In ai.(kCl, May. Moose Factory, Hudson's Bay Territory) there Is an oblone 

 spot of chesluul lu the middle of the crown, but generally this Is absent. Very frcnuontly 

 the chestnut tlnsos the throat. All variations In these respects appear, however, to bo 

 Individual, and not dependent at all on locality. West Indian specimens appear to be 

 ab.solutely Identical with those from North America. 



"Autumnal specimens are browner, the chestnut markings much obscured.* iBiaL X.

This was until within comparatively a few years a rare bird, 

 whose habits were by no means well known. It passes through Illi- 

 nois during its migrations, but does not, so far as known, remain 

 to breed, although in the mountainous portions of Hayti and Jamaica 

 and perliaps others of the Greater Antilles, it is a permanent resi- 

 dent; thus having a very peculiar distribution, like the Yellow 

 rumped Warbler {Dendroica coronata) and possibly other members 

 of the family. 



With the exception of two, which were taken in an orchard (when 

 the apple-trees were in bloom), all the specimens of this species 

 secured by the writer were shot from tall tree-tops, the height being 

 80 great that it was impossible to identify the species. It therefore 

 seems likely that most examples evade the collector by keeping in 

 the tree-tops at such an elevation that they cannot be distinguished 

 from other Warblers. 



Mr. Nelson (page 99 of his catalogue) says of this species in 

 northeastern Illinois : 



"Very common migrant. May 7th to 25th, and September 5th to 

 20th. In spring, found almost exclusively in the tops of the trees; 

 in autumn found in large numbers along roadsides, borders of woods 

 and llflds in company with DeiKbara jnilmarum, from which it is, 

 with ditliculty, distinguished at gunshot, so closely alike are their 

 habits and movements at this season."
