This beautiful little bird was common in summer throughout the Wah- 

 satcli district, being one of several eastern species which have their westward 

 ran"-e limited only by the commencement of the arid aiul treeless region 

 of the Great Basin. It was abundant in the valleys and the lower portion 

 of the canons, but it did not extend far up into the mountain.-*. A few were 

 seen, in June, in the orchard of the "Church Itanche," on Antelope Island.
