Thanks!
I appreciate such specific information. I will look for the plants mentioned. I had no idea there were so many kinds, but live & learn, right? So far I've been lucky & had plants by accident that they liked, or at least seem to like (hosta, butterfly bush, cannas, petunias, hibiscus, etc.) I've only been doing gardening & general yardwork for 3 years, & knew NOTHING about hummingbirds before that. Again, lucky me, they just appeared in my back yard one day & I ran & bought 2 feeders. They are now such an important & joyful part of my summer. Wonderful entertainment. Can't imagine summertime without them.
I thought my regulars had come back early (early April) because a bird hovered right in the spot that I normally hang a feeder, but hadn't put it out yet. Naturally, I ran into the house & started working on mixing some up. I have seen them only sporadically since then, but my feeders have steadily been going down. Do birds remember feeder locations when they migrate? If they do, they are even more fascinating, considering the long distances involved.
