Observation details

Following up on a report from here on August 11th, I found an immature Black-crowned Night-Heron foraging along the boulders below the dam here. The bird flew down to the rocks from an unseen position and then peered at the water, tipped beak down toward the water for an extended period. Typical night-heron, being a rather stout and squat medium-sized heron. Overall brown with large whitish, triangular and elongate spots on wing coverts and scapulars. The underparts were coarsely streaked. The bill was greenish at the base and a medium long spear shape. The loral skin was green. The irides reddish-orange. The legs yellowish-green. Yellow-crowned eliminated by lack of narrow pale edge along outer margin of greater coverts and large rather than small white tips to coverts. The bill color and shape were also unlike Yellow-crowned, which would show a mostly black, stouter and blunter bill. The body shape was typical of Black-crowned and not long-necked like Yellow-crowned.
