Mexico and Central America, its southern migration extending to the Isthmus of 
Panama, but not beyond it, as hitherto we have not met with any instance of its 
occurrence on the mainland of South America. In many of the West-Indian Islands 
too it is common at this season; and it also reaches Bermuda. In Mexico its presence 
has not been noticed on the west coast until we come to the Isthmus of Tehuantepec; 
but on the east side it is abundant, occurring everywhere, according to Prof. Sumichrast, 
in the neighbourhood of Orizaba *. In Guatemala we also found it in all parts of the 
country up to an elevation of 5000 or 6000 feet. It frequents the more open districts, 
where scattered bushes grow, rather than the denser underwood. A bird in summer 
dress is rarely met with in Central America; and the same may be said of Cuba, where 
Dr. Gundlach says that the birds begin to moult just before leaving for the north, and 
that he has never obtained a fully moulted bird in the island. In Jamaica, however, 
it has been stated, on the good authority of the late Mr. March, that it occasionally 
breeds ; and skins and eggs of it were once sent to the Smithsonian Institution by that 
gentleman ®. 
The United States also afford winter quarters to D. coronata. ‘Thence it migrates 
northwards to breed, and passes this season in the high north, a few pairs remaining in 
northern New England and Nova Scotia. Of its nesting-habits not much is known. 
Brewer describes a nest from Nova Scotia, which was taken from a horizontal branch of 
a tree, as composed of fine stalks of grass, slender twigs, and roots, the latter forming 
the rim; the lining was of soft grasses, downy feathers, and fine hair. Nests taken by 
M‘Farlane on the Anderson River were generally built in low spruce-firs or on the 
eround. The eggs are white, sometimes with a bluish shade, and blotched and spotted 
with several shades of brown, reddish brown, and purple. 
A very full account of the nomenclature of this bird will be found in Dr. Coues’s
