I've been through all my books and mostly know what this isn't but can't figure out what it is. I figure it must be a juvenile something but now it's time to ask for help

This picture was taken along a tannic, brackish area of a river in west central Florida. The bird was amongst the mangrove roots near flats and oyster beds. It acted like a night heron the way it just sorta disappeared into the bushes.

Thanks for your help,
