觀察細節
Count by twos. None seen until 0910, when I saw a single bird flying east high overhead. Later, groups of up to 20 seen sporadically in flight over the creek. I saw at least 1 BARS with one tail "streamer" conspicuously shorter than the other. Could it be molting already? BNA states that flight feathers are generally replaced after leaving North America; could this be wear showing on year-old feathers?
