686 GEOLOGICAL SUEVEY OF TPIE TERRITORIES. 



(Sub-family Agelainw, the Starlings.) 

 DoUchonyx oryzivoms, (bobolink; reed-bird:) 



Hah. — Eastern Nortb America to Kocky Mountains; westward to Salt 

 Lake and East Humboldt Mountains. 



The only place on our route where we met with these birds was in the 

 Great Salt Lake Valley ; here they were quite abundant. 



Agelaius plioeniceus, Vieill., (red-winged blackbird:) 



Mah. — United States, from Atlantic to Pacific. 



Eed-winged blackbirds were very common near Ogden, where they 

 were breeding. This, as well as the jDrecediug species, is too common 

 to need descrii^tion. 



Xanthocephalus icterocejyJialus, Baird, (yellow-headed blackbird :) 



Hah. — Western America, from Texas, Illinois, Wisconsin, and North 

 Eed liiver to California, south into INIexico. Greenland, Eeinhardt. 



I saw a few yellow-headed blackbirds in a marsh near Salt Lake. The 

 only other place where we found them was at Marsh Creek, near Car- 

 penter's Eanch, Idaho Territory. Here I obtained four good specimens 

 and one nest. The nest was fastened to a clump of rushes in a marsh, 

 about five feet above the water, and was composed of dry swamp-grass. 

 It had no lining, and presented the same appearance inside as out. It 

 was very solid, and contained four nearly fresh eggs of a light greenish 

 color, covered with darker spots.
