Perhaps rare, but a single specimen ha-sang been secured at Lron Springs, 

 Utah, October 4. Not recorded before from so for west. It is by no means 

 certain that the occurrence of this snowbird here is merely accidental. The 

 specimen obtained was shot from among a flock of the Junco oregonus, 

 which was exceedingly numerous ; and, its true identity not being known 

 at the time, I took no pains to ascertain its relative numbers as compared 

 with oregonus. It may occur during the migrations regularly.
