A fellow photographer pointed out this nest where he had seen three Yellow-crowned Night-heron chicks the day before. With the fuzzy head and how he was mostly laying down I’d guess a week or 10 days old.
After a bit the first chick and one nest-mate, rather camouflaged to the right in the twigs, stood up for a look around.
From a different angle a quarter of a way around the tree I spotted one chick. He looked older, but it’s hard to say for sure with the curtain of Spanish Moss.
If you zoom in you’ll see an eye of a second bird to the left of the standing bird, at nest-top level, just before the big clump of Spanish Moss.
