HI.- 



Xanthocephalus icterocepkcdus. 



Tlie color of the yellow in this species 



varies considerably ; sometimes being 



almost of a lemon -yellow, sometimes of 



a rich orano'e. There is an occasional trace of yellow around the base of the 



tarsus. Immature males show every gradation between the colors of the 



adult male and female. 



A very young bird (4,3.S2, Dane Co., Wis.) is dusky above, with feathers 

 of the dorsal region broadly tipped with ochraceous, lesser and middle wing- 

 coverts white tinged with fulvous, dusky below the surface, greater coverts 

 very broadly tipped with fuh-ous-w^liite ; primary coverts narrowly ti]iped 

 with the same. Whole lower parts unvariegated fidvous-white ; head all 

 round plain ochraceous, deepest above. 



Habit.s. The Yellow-headed Blackbird is essentially a prairie bird, and is 

 found in all favorable localities from Texas on the south to Illinois and 

 Wisconsin, and thence to the Pacific. A single specimen is recorded as hav- 

 ing been taken iu Greenland. This was September 2, 1820, at Neiiortalik. 

 Eecently the Smithsonian Museum has received a specimen from New 

 Smyrna, in Floritla. In October, 1869, a specimen of this bird was taken 

 in WatcrtoN^'u, Mass., and 'Sir. C'assiii mentions the capture of several 

 near Philadelphia. These eiTatic aj>i)earances in places so remote from their 

 centres of reproduction, and from their route iu emigration, sufliciently attest 

 tlie nomadic character of this species. 



They are found in abundance in all the grassy meadows or rushy marshes of 

 Illinois and Wisconsin, wliere they breed in large communities. In swamps 

 overgrown with tall rushes, and partially overtiosved, they construct their 

 nests just above the water, and Imild them around the stems of these water- 

 plants, where they are thickest, in such a manner that it is ditlicidt to
