The juvenile Night-Herons were more active on this morning in the rookery than the snoozing adults. 

A few of them were wandering around on these gnarly tree branches in the dappled sun.

A comparison of the juvenile Yellow-crowned Night-Heron and juvenile Black-crowned Night-Heron at All About Birds finds they are quite similar, with the Black-crowned variety having “larger spots and bolder streaks.” Hard to tell unless you have one of each side-by-side.
