I don't know Tee
I will tell you the story on the ruby throated one. It's very sad. It was the week before Easter. Hank found a ruby throated hummer on the driveway with a broken wing. Between the vet and google, we did everything we could to save her including fixing her wing. She lived for two days and then died. I just sobbed when she died. We buried her in one of the gardens. She was so tiny and innocent. It broke my heart that we couldn't save her.
The other hummers we see are brown? We had SO many this year that sometimes I was filling the feed 2 times in one week and it's a big feeder.
