Many thanks to Heather Jack for the wonderful photographs.
Report from David Pryor posted on ONTBIRDS ..."The juvenile Yellow-Crowned Night-Heron has been roosting in a tree along with an adult and juvenile Black-Crowned Night-Heron, low to the water, on the north east side of the island in the marshy cattail overflow pond located about 50 yards due east of the southernmost parking lot. The bird was best seen from the gravel path which runs north and south on the east side of the pond
In comparison to the other juvenile bird (which is clearly a Black- Crowned), the bird's upper mandible is largely blackish while the lower mandible, other than the tip, appears somewhat pale. The bird has grayish rather than brown upper parts, has much more finely spotted wings, seems to be longer-necked and legged, as well as showing a blunter, thicker bill. This bird's call was is relatively high-pitched, almost like a scream."
