8o Wyoming Birds. 



759a. Hylocichla guttata auduboni: Audubon's Hermit Thrush. 

 Knight gave but one record. Metz has found it nesting. 

 Blackwelder records it from the Teton region. Taken by 

 Lockwood from near Laramie. 



761. Planesticus migratorius migratorius: Robin. 



This form occurs in southeastern Wyoming. It and pro- 

 pinquus are both found here, the latter in far greater num- 

 bers. 



761a. Planesticus migratorius propinquus: Western Robin. 

 Very abundant summer resident over the entire state. 



766. Sialia sialis sialis: Bluebird. 



Knight was doubtful as to whether or not this bird breeds 

 in Wyoming. His only records were that several specimens 

 had been taken by Bond of Cheyenne. Peabody now records 

 it, and Clearwaters has seen it nesting in Laramie County. 



767a. Sialia mexicani bairdi: Chestnut-backed Bluebird. 



"There is only one authentic record for Wyoming. This 

 was made by McCarthy, who took a specimen on the Sweet- 

 water River in 1859. There is no doubt but what they 

 frequent southwestern Wyoming and probably breed." 

 (Knight.) 



768. Sialia currucoides: Mountain Bluebird. 



Abundant summer resident on the plains and timber land. 

 Found over the entire state. 



Passer domesticus: English Sparrow. 



This bird is gradually spreading in Wyoming and has 

 reached almost all the towns. It is seldom seen at any 

 great distance from towns or ranches.
