Allen's or Rufous Hummingbird? La Jolla, CA, USA (2 Viewers)

Is it possible to determine whether the bird in this photo is an Allen's or a rufous hummingbird? The photo was taken on 12/25/23 at La Jolla Cove, near San Diego, CA. I'm calling it an Allen's Hummingbird for now because I also spotted a male Allen's in the area. (The 4th & 5th photos are of what I think is a male Allen's Humingbird.)

It is probably impossible to say for certain for the bird in the first three photos, but Rufous is all but entirely absent from San Diego County at this time of year while Allen's is common, and there is nothing here to suggest it is not Allen's. The bird in the forth and fifth photos looks perfect for an adult male Allen's Hummingbird.
