various parties of the Expedition at many different points in Utah, Colo- 

 rado, New Mexico, and Arizona. Any patch of" shrubbery or tangled 

 growth of bushes is sure to be selected as the summer abode of one or 

 more pairs of these birds. From such localities in tlie low valleys, they 

 follow the streams upward as they flow from the mountains; and, up to an 

 altitude of about 9,000 feet, the species is common. Its song, though short, 

 is sweet and pleasing, and in early summer is repeated at very brief 

 intervals, as the birds pause now and then in their industrious search under 

 fallen logs and among the dead leaves for insects. During the migration, 

 a general diffusion of their numbers takes place, and, below the height 

 above mentioned, they may be met with almost anywhere except on 

 perfectly open ground.
