観察結果の詳細
I observed and photographed the continuing White Wagtail (ocularis ssp.) on 3-29-2020 from about 4:27 pm to 4:57 pm from the usual observation point on the bluff on the south side of the Colorado River near the playscape and pavilion accessible from Grove Blvd. When I arrived at 3:58 pm, water was being released from Longhorn Dam and the gravel bar on the north side of the Colorado River as well as the island upstream was underwater. After the release ended and the water began to subside, the wagtail appeared on the gravel bar on the north side of the river almost as soon as there was a place for it to alight. I observed and photographed the wagtail on both the north and the south (the side of the entry gate and the observation point) banks of the river.
