Well I think it is time to take down our hummingbird feeds for this year. We haven't seen a bird in near about two weeks now. And since our temps have been in the 90's during that same time, I can say that temps are what drives them to migrate but available daylight hours. Those little birds have an internal clock that tells them it is time to leave.
One thing I wish I could find is a hummingbird nest. In all the years we've feed these little birds, I've yet to see even one of their nests. I realize their nests are very small, and we do have tons of trees, so one day maybe I'll stumble across one of their nest accidentally. I watched them fly into the trees from the feeders lots of times, but haven't seen where they sleep (for lack of the correct terminology) at night or have their young hatch.
So much for this year. I will see the males return in early early spring like usual.
