Observation details

Two immature Night-Herons flew over the southwest corner of Metzger Marsh, headed northeast, from the direction of Howard Marsh. Both Night-Herons were only seen in flight in a spotting scope and then through the camera. The first was clearly an immature Black-crowned Night-Heron, while the second seemed not as thick-necked/bulky, having feet that went noticeably past the tail, and, despite the evening light, noticeably contrasting/two-toned upper wings. After that brief view in the scope, the rest of the view was through the camera taking pictures to confirm the suspicion. In the photos with both Night-Herons, the Yellow-crowned Night-Heron is always on the left. Additional features seen in the photos (but not in the field) include thinner, longer, and more pointed wings, pale margins on the greater coverts, and a different bill shape.
