觀察細節
Heard vocalizing, then into sight, very low overhead from the north. Total of six corvids kettled up briefly into tight circle very high and then continued to circle east and out of sight. Based on vocals, at least two were ravens. Visually there appeared to be some slight size difference among them and as such some could have been crows.. hard for me to judge even looking at the tail shape in photos.
