A quick grab of an accidental encounter, my first ever, with this tiny bird - smaller than a chickadee, on which I spied a tell-tale red spot on the back of the head. Posted it on a Facebook bird group and got the ID. Very exciting. I'm hoping he comes back in better light when I have a more suitable camera and lens to work with. Having read the following information I am even more excited about having spied this bird: https://www.allaboutbirds.org/guide/Ruby-crowned_Kinglet/overview
