Female Ruby-throated hummingbird at dusk

I was sitting on the swing when she came down just to relax and feed
before retiring for the evening.
She sat there for at least 20 minutes untill I had to get up.
Every evening and morning both male and female(mostly female)
will just sit and clean,look around and visit the flowers.
They like the feeders too but seem to favor the hyacinth bean vine
which she is sitting on, also the cardinal climbers and my excessive
amount of tall orange cosmos.
