I’m not very sure if this was Allen’s or Rufous Hummingbird, but according to iNaturalist identification, there was no notched tail feather, so it’s likely Allen’s. Tell me if I’m wrong!
There was actually a pair of them, and the male (?) was performing a courtship ritual (??). Very sad that I did not get both of them to be in focus, but watching that display was one of my happiest moments. So sweet <3<3<3
