I do still have a few hummingbirds! The behavior is different ... they are spending a long time on the feeder, drinking & drinking. The first one I saw this morning had its head down so long drinking, I was beginning to wonder if it was stuck or something, not that I could imagine how that would happen. They are definitely filling their tanks for the migration flight before taking off. There were so many not long ago, we could have used a hummer version of ‘air traffic control’, but now it’s one every couple of hours. I would imagine that by the weekend, except for a migrating straggler stopping by, they’ll all be gone for sure.
I am glad I am still seeing a few ... gradually ‘weaning’ myself off of seeing them so often every day & having them “buzz” me when I am replacing the feeder after a fill up. Cold snap coming this weekend so they are leaving in time to avoid it.
They are probably migrants and are arriving hungry. You should check out this Webcam in Cslifornia. I check it out in the winter.
