This study is fascinating. The question, did they evolve independently or have common ancestors leads to interesting unanswered questions. I wonder if they will be able to find the answer in DNA? When did DNA studies start, do you remember?

"The DNA profiling technique was first reported in 1984^[3] by Sir Alec Jeffreys at the University of Leicester in England,^[4] and is now the basis of several national DNA databases. Dr. Jeffreys's genetic fingerprinting was made commercially available in 1987, when a chemical company,Imperial Chemical Industries (ICI), started a blood-testing centre in England.^{[5]" Wikipedia.}

^{It probably wasn't yet available for this study. That means we may have an answer to this question.}

I love hummingbirds.  Each summer I put out feeders for them and they visit frequently.  I know their little chirps even when I don't see them.

Oh same here. I have a feeder and some plants that produce flowers that Hummingbirds love.
