I did not get a good look at the entire bird and would speculate that the tail was obscured by a branch. The body of the bird was the approx size of an adults thumb. I was struck by the color; which is what caught my attention. I agree on the comments re size being hard to judge - as I’ve gone back and looked I was able to generate an estimate based on the size of the branches and backdrop of where it was perched as best I could. Frankly it looked and moved like a large humming bird…
Date - today 6/20
Habitat - Rural Residential, agricultural area. In a yard perched in a pine tree, outside branch, near the top around 30 feet. Had very quick flight pattern in bursts.
