觀察細節
About 75 ravens were feeding in the feedlot. All the ones calling were Chihuahuans and I could often hear 5-10 calling at once. Up to 30 or more were visible at the same time and they all appeared to be the same size. Some ravens I only saw for a few moments when they flew from one place to another and they may have been Commons Ravens.
