Mike,

I've just finished looking over "Identification of Hylocichla/Catharus
Thrushes. Part I." (Birding 32: 2. April 2000) which deals with
identification of Hermit Thrush (in part) and Part III (Birding 32: 4.
August 2000) which covers Gray-cheeked Thrush and note "some Pacific Coast
birds almost lack an eye-ring, and can show a face pattern suggestive of a
Gray-cheeked Thrush, as this individual [in the photo] does ... If seen in
right angle, the rufous tail (albeit not a bright one) of this individual
would confirm the identification of this individual as a Hermit Thrush." I
did not note any rufous in the tail, but this bird was in shadow and I could
have missed this. Despite effort, I have not refound this thrush, though I
and Richard Repp are still coaxing obvious Hermit Thrushes into view.

So, I am now wiser and more fully aware of the plumage variation of Hermit
Thrushes. However, during the three or four minutes I had these birds in
view together (coaxed by spishing), the Hermit behaved in characteristic
Hermit fashion, with its usual tail cocking posture. Never did the darker,
larger bird, behave in this manner. I don't know how much behaviour is worth
in the suite of characters one should check, however.

Thanks for your post and help on this.
