|Song or call & method of delivery:||The birds were silent when I saw them. However, on recent outings to this location I had heard calls I didn't recognize. After seeing the birds, I consulted All About Birds and listened to the calls available there. The three different recordings were a good match to what I'd been hearing.|

|Habitat:||Deep cut creek bottom, steep bank.Sagebrush and Rabbit Brush up on top. Dense trees and thick underbrush in the bottom. Small live stream runs year round.|
were they eliminated:
Hermit Thrush much smaller, brown gray above, rust color only on tail, and
spotted breast compared to streaked Brown Thrasher. Hermit Thrush also has
stubby body shape and more upright posture on the ground.
Sage Thrasher is smaller, pale in color, and bill quite short compared to BRTH. I have not seen SATH in this habitat, or at this time of year anywhere in Grand County.
this & similar species:
I am familiar with the Brown Thrasher from the years I lived and observed birds
in Illinois. The BRTH is a nesting species there. Most recently I saw them in
June of 2014, singing. I had not heard BRTH calling since 1980, hence my
inability to ID the calls I heard previous to this sighting.
I see Hermit Thrush in this location, generally in Fall and Winter
I see Sage Thrashers in this area, not this habitat and not at this time of year.
