The Willow-Thrush is a scarce migrant and summer resident in 
Colorado, or else it has been overlooked ; it has only been noticed on 
the plains and along the foothills of the eastern base of the mountains, 
and does not reach an elevation of much more than 8,000 feet. It was 
found nesting by Henshaw at Fort Garland at about 8,000 feet, 
and it was with one of these specimens that the subspecies was 
first discriminated by Ridgway; it was subsequently met with by 
Gale in the Boulder hills, while the other records, chiefly migratory, 
are: Denver, May 17th (Henshaw), north fork of South Platte, 
between Denver and South Park (Allen), at 8,000 feet near Idaho 
Springs (Trippe), and various localities in the plains of El Paso, 
Elbert and Lincoln cos., from May 15th to June 6th (Aiken coll.).
