Looks like this one is a Chipping Sparrow. Fairly common I guess, but had never seen one around the feeder as long as we've had it (a few years now).

Donna -- THANK YOU! We looked at the Junco, then the Towhee -- and then the Redstart. DH says it's the Redstart for sure. I see they are really travelers, migrating far and wide. Glad one migrated into our neighborhood. Sorry I didn't get to see him. Thanks again. Sue

I guess I wish instead of a knee jerk "this is different and I don't like it!" reaction, people could be secure enough in themselves and their own identities to say something like: "Wow, I've never had those thoughts and feelings about my gender but clearly this other person has...how interesting that we don't all go through life on the same path." NYT and CBC have been giving time to Elinor Burkett, previously known as the woman who Kanye'd the Oscars, to tell everyone that men and women's brains are exactly the same and that it's periods and growing up in fear for your physical safety that make a woman (because trans people don't have to worry about violent attacks). So since she's never had a period, Caitlyn in no way knows what it's like to be a woman and why don't those angry trans folks shut up already (PS she apparently thinks that not only are trans women not women, but trans men are also not women? I wonder how she feels about women who've never ovulated?). Who in the world thinks there's only one way to be a woman?! I hope to God I have more in common with Laverne Cox than this kook, at least in terms of class, empathy and intelligence. It's jerks like this that give feminism such a bad name.

It could be seedling of one of the hardy sedums, do you have any in the garden? What zone are you in? Agree with Garret - another possibility could be kalanchoe.
