I have both thrushes and robins. The thrushes seem to just pass through but once the robins come, they stick around. The other birds I get on a pass-through basis are evening grosbeak, which I call the clowns, both for their bright coloration but also their behavior. They just seem comical to me. I have 4 feeders in view of my office window and the various birds keep me amused during lag times (waiting for the dang computer to reboot, waiting on hold for extended periods, etc...)
