Ah! Here in the Midwest we have ruby throated hummingbirds, which are migratory (and mighty!). They have an amazingly long migration for such tiny creatures. It is a miracle of nature that they can do it. I don’t think they could survive our winters - very cold, no flowers, no insects - and even feeders would freeze solid. But I look forward to their arrival each spring and plant many flowers with them in mind - I try to have something in bloom for them from spring through autumn.
@Myrth Yeah, Anna's Hummingbirds are non-migratory. A lot of people have feeders out for them so they seem to do just fine over winter, even when it surprise snows.
