COBirders,
I thought I sent the email below last Wednesday night but because I sent it with the wrong email address it bounced (after more than a day I think). It refers to Nick Komar's quick reply to my query that evening.

Nick (and COBirders),
Thanks for the detailed comment on Jim Thompson's photo. My assumption that the bird was a fledgling stems from its partial mask that does not extend toward the nape. We frequently get both Northern and Loggerhead shrikes on the Pueblo CBC and I have not noticed any with such an abbreviated mask. Now I know I need to spend some time looking at shrike photos and observing more carefully in the field. Hats off to Jim who, as you have confirmed, nailed it. :-)
