I did attempt it last fall, when Goldenrod was blooming. I staged feeding stations and watched them leave for a couple of miles. They are in a cemetery - OR on the other side of it, in fairly human-dense private property in Fort Worth - someone's attic, a high utility box? Either way, since I don't want to get shot for trespassing while FINDING the place, I abandoned them to winter. But I do believe they are alive, the one I saw this afternoon in my yard headed northwest (the direction they went.)

If my visitor today is any clue, they'll be coming to visit me. I am flower central. First blooms are usually my snowdrops, but I think I'll have to dig them out of the bermuda grass overgrowth, that bed was invaded last summer.
