Hummmm

I think these are male and female Ruby Throated Hummingbirds. We get more than one pair.

When I'm out on the deck taking care of the flowers I hear that Humm or Buzz sound they make, like a huge bumble bee only louder.
If I'm real still sometimes they will fly up to my face to check me out before they decide it's alright to go to the feeder or the flowers nearby. They are precious.

Sometimes one will come and knock another off the feeder and I hear little chirps.
