As you know our back yard is our favorite feature of our home.. and we spend most of our sitting time in the family room which overlooks it through the 3 6x8 foot windows. It is in these chairs where we browse our computer and tablets, read our Kindles, papers and books, and watch the ever-changing wildlife shows in the bushes and trees.
We have a funny little iron and vine "tree" which has some lights on it that sits just outside between the windows and the pool. Each of the last 3 days this little guy has come to visit. He is a Ruby-Crowned Kinglet and is the only one we have ever seen. http://www.allaboutbirds.org/guide/Ruby-crowned_Kinglet/id
The red crown appears to change in size as he chooses to display it. He doesn't sit still for more than a second and hops all around but seems attracted by the tree. He also sits briefly and looks into the window at us. He didn't even fly away when I stepped outside to take a picture with my cell phone. The others are taken through the window.
He pays no attention to the two main bird feeders and the other visitors there; just our little weird tree. Maybe it's the red lights. Always something going on in the back yard.
