Anna’s hummingbirds

The one with his wings open flew in, stayed for half a minute, then flew out. The other one was not particularly aggressive, perhaps because it was too cold, or out of breeding season.

Also saw a butterfly I couldn’t identify, very close to an Empress Leilia but lacking some of the identifying marks. Perhaps through loss of some parts of the wing.
