strangling flocks from October 1st to 10th, and remains until the first 

 of May. During the last of March and first of April, large straggling 

 flocks pass north. An unusually large flight took place the 20th of 

 March, 1873. A continuous series of large flocks occupied over two 

 hours in passing. Those remaining after the middle of April are in 

 breeding plumage. 



94. P. pictus Sivains. PAINTKD LOXGSPUR. Common migrant. 

 March 30th, 1875, near Calumet Lake, I found a flock containing about 

 seventy-five individuals of this species. Their habits were quite sim- 

 ilar to' those of P. lapponicus while upon the ground, except that while 

 the latter species preferred the wet portions of the prairie, the former 

 were found only about the higher portions. When flushed they inva- 

 riably uttered a sharp clicking note, rapidly repeated several times. 

 When driven from their feed ing- place by my approach, they would 

 ,rise, iu a loose flock, and after wheeling about a few times start off in 

 a direct line, gradually rising higher until they disappeared. After a 

 short time their peculiar note would be heard, and darting down from 

 & considerable height they would alight near the place from which 

 they were driven. Although the flocks of P. pictus and P. lapponicus 

 often became mingled while flying over the prairie, I did not see them 

 alight together.
