Icterus bullockl. Bullock's Oriole. 



Summer resident ; common. Arrives about May 10. Most 

 of them leave the latter part of August ; the latest date: at 

 hand is September 14, 1903. 



Orioles are found all over the County wherever there are 

 trees, below 8,000 feet. When the leaves are gone from the 

 trees in autumn many of their pensile nests are seen hanging

 Cottonwood trees, these being the most suitable kind we have

 no black on the head, this being rather bright yellow. 



Euphagus carolinus. Rusty Blackbird. 



Rare; but one record for the County, 3 seen and 2 killed

 few records of this species for Colorado, and this is the only 

 one south of the Divide. 



Euphagus cyanocephalus. Brewer's Blackbird. 



Summer resident ; common. Arrives the last week in 

 April. Most of them are gone by October first, but it has been 

 known to remain until January 1. 



Brewer's Blackbird is one of our most common summer 

 birds, seen everywhere about the ranches on the plains and up 

 into the mountains, where a great many breed, gathering after 

 the breeding season is over into flocks, often of large size. 

 Since Monument Valley Park has been established a number 

 are there every season, at the north end, and L. L. Shaw found
