This female continues to hang out in the backyard often perch on the same patch of blackberry vines.
I haven't seen any signs of nest building, but I remain hopeful.
I had two males, but sadly lost one last week.
He was perched on the feeder in the morning when I came outside. Appeared to be in torpor with his bill uplifted and no movement other than breathing. He never came out of the state. I was bummed for several days afterward wondering if I could have / should have done more.
Thankfully, there is still one male in the area.
And at least two females. In a couple of months the Rufous Hummers will return and I'll have lots of humming activity.
