I also should have mentioned that they saw only one Tufted Titmouse.

My lone observation is not useful, but when many observers-and spring census and Christmas bird counts concur (do they?-I don’t know that)-then perhaps we have a trend. If memory serves me correctly (and it often doesn’t), Sylvia Halkin’s speculation is that competition between this species and Tufted Titmouse is a possible mechanism for this population shift.
