416 THE ORANGE-CROWNED WARBLER, 



May, and breeds from New England northward to high 

 latitudes, going casually even to Greenland. It is also 

 reported from the Pacific Coast. 



THE ORANGE-CROWNED WARBLER. 



Belonging to this same genus, and very similar in size 

 and coloration, is the Orange-crowned Warbler (Helmin- 

 thophaga celata). But while it is difficult to distinguish the 

 immature birds, in complete plumage, the difference is quite 

 appreciable. In the case of the Orange-crown, the oliva- 

 ceous of the upper parts, and especially the yellow of the 

 under parts, is not so bright as in the Nashville Warbler; be- 

 sides, it lacks the ashy on the head, so conspicuous in the lat- 

 ter, and instead of dark chestnut, the crown is a rather pale 

 orange. Sometimes this latter mark is entirely wanting. On 

 the whole, Orange-crown appears a little the larger of the 

 two. Common in Florida during the winter, it migrates but 

 rarely into the Northeastern States, but becomes common 

 to the west and northwest, and even abundant along the 

 Pacific Coast. 



"A nest of the Orange-crowned Warbler, taken June 12, 

 1860, by Mr. Kennicott, at Fort Resolution, Great Slave 

 Lake, was built on the ground inside of a bank among 

 open bushes, and was much hidden by dry leaves. It con- 

 tained five eggs. This nest is built outwardly of fibrous 

 strips of bark, interiorly of fine grasses, without any other 

 lining. The eggs are very finely dotted all over thickly 

 about the large end, more sparsely elsewhere with pale 

 brown. They measure about .67 X-50." (Coues.) 



The Tennessee Warbler {Helminthophaga peregrind) is a 

 delicate beauty, bearing some resemblance to the last two. 

 It is quite rare in these eastern regions, but common to the 

 westward, even abundant, in the migrations, along the Red
