Sunday evening I had a brief look at a hummingbird in my Ft Pierre Backyard. The brief look made me think Rufous. Rufous is the species that wanders east etc. Broad-tailed rarely wanders east. In SD I only know of Peter Binstock's sighting in Tripp County last year. Broad-tailed usually migrate straight south. It is a few weeks early for either Rufous or Broad-tailed to be migrating.
Ruby-throated has not been documented breeding in Pierre area and it is early or late for a migrant
But after 2 days I am able to feel that I have a valid ID. After many photos and hours. I believe it to be an adult female Broad-tailed Hummingbird. Female Rufous & Broad-tailed hummingbirds can be very difficult to identify
