Interesting Green Heron Behavior on Wrightsville Beach (1 Viewer)

We are visiting Wrightsville Beach (right next to the Coast Guard Station on the southern side) and there is a tree (right on the beach) that fills up nightly with Green Herons. I want to say there are about 30 of them. It is a bit dark, but we've been two nights now and are pretty sure they are Green Herons and not something else. Since it is dusk, its not easy for us to get a perfect ID, but the only other thing that might make sense would be that they were all juvenile night herons or something, which seems unlikely.

Sibley (small) says that Green Herons don't typically roost together, so this is a bit unusual. Anyone else seen this behavior before with greens? Maybe its something they do during mating season?
 
Here's what BNA-online (an authoritative source) has to say on this subject--

"May roost at night alone or in association with conspecifics or other colonial waterbirds. In mixed-species roosts, tends to segregate to a place adjacent to main roost. Up to 100 birds counted at one New Jersey roost."

Thanks! That seems to confirm the behavior has at least been observed by others.
