Nesting, similar to that of the preceding. 



" Their habits are quite similar to those of P. lapponicus while 

 upon the ground. . . . When flushed they invariably uttered a sharp 

 clicking note, rapidly repeated several times. When driven from their 

 feeding place by my approach they would rise in 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 pecul- 

 iar note would be heard, and. darting down from a considerable height, 

 they would alight near the place from which they were driven "
