Great photos, all.
Josephine, those first two photos look like little elfin feather dusters.
The little red thing in my photo is a Northern Cardinal (Cardinalis cardinalis).
It was the first "winter" photo I could find. I feed a lot of birds in the wintertime, even the crows. I don't do garden clean-up until spring so the critters can have the seeds and anything else that's left.
Some things in the yard:
Wild violet (Viola sororia var. sororia)
Phlox subulata:
