[pct-l] Cascades bird identification help

[Brett]

I know it only by its call. Or rather, by their communal 
calls, back and forth among the boreal treetops in the 
Cascades of Washington. The aural effect is somewhat akin to 
a dozen landline telephones each chirping at its own unique 
pitch and tone, but way more beautiful than that. In fact 
its haunting appeal is right up there with the hermit 
thrush. Could it in fact be a thrush, perhaps a varied 
thrush?

Northbound thru-hikers may be unfamiliar with this bird's 
call. I don't remember hearing it in these areas along the 
PCT during the latter part of August into early September. 
What a treat for southbounders, though.
