We got rain in yesterday, right about the time I got off work and took the dogs for a walk....of course!  When I got back, I noticed that the hummers had drained the feeder - I filled it on Saturday!  I refilled it for them, and then noticed just how many hummers I had.  There were even more that I couldn't capture in either the pictures or the video - they were everywhere!  I think they are migrating, coming back into the valley for the winter.
