By Thanksgiving, Vermilion Flycatchers migrate to the warm Southern California, San Joaquin Wildlife Sanctuary in Irvine, for the winter. I was waiting next to the tall tree which favorable to Red Vermilion. Suddenly, unfamiliar bird that I never seen it before, landed on that high perch. I shot more than 30 frames of that unknown bird's image. One of photos showed a split moment of eating a Dragonfly by Merlin, which is a smallest falcon.
