観察結果の詳細
Silent; SY based on the retained tertial. My initial impression was GRFL - long tail, yellow belly, overall pale from the view in 4 of the photos. The bird didn't have the compact shape of HAFL, or the (often) peaked crown, or a tiny bill. However, the tail was going up and down rapidly, not the slow steady drop movement I'm used to seeing for GRFL. Then looking at the photos, it's clear the eye-ring is not round as in GRFL, and the lower mandible doesn't have a dark tip, nor is the color yellow . . . although bill color doesn't seem to be consistent with empids. So that leaves DUFL - the bill size is right, there is no obvious long primary extension as on most HAFL, and the crown shape fits.
