Question for OT Ornithologist. Black birds and White birds on the LSU lakes.

While jogging around the smaller of the two lakes, I often notice hundreds of birds perched on certain trees in the lakes. Some of them are black, some of them are white
The weird thing, is that they segregate themselves on the trees with the top half of the tree filled with black birds and the bottom half of the tree filled with white birds.
Anybody know why they do this? And which part of the tree is the most desireble for birds?

The black birds are on top?
Looks like whitey is in its proper place

The white birds are water birds so they stay closer to the water?

We've got so much work left to do, y'all

The bottom part of the tree is the regular wood and the top part is what arborists refer to as "goodwood"
In regards to the birds, it's pretty much all black once you cross goodwood

Predator looking up into the light will see the white and it will blend in to the light providing camouflage. A predator looking down from above will see the black which will blend in with the ground or water below providing camouflage. This is similar to how fish have white bellies and dark backs.
Seems to be a mutually beneficial roosting arrangement.

It's proof, on a small scale, that all species prefer grouping with the identical species, even when around the same catagory, birds in this example.

Birds of a feather... duh!

While it seems the black birds are on top, if you're under the tree looking up, they're in the back of the tree.
It's all about perspective.

The black birds are cormorants and they typically roost/perch at the top of trees. Yes, they can swim. Almost too good. They swim underwater and eat fish. They often work together chasing fish, kinda like herding cattle. They can wipe out a fish population in a pond with the quickness.
The white birds are egrets. They just roost in the trees overnight and typically leave the trees during the day to go do egret things like eat stuff, hang out with cows, and wade in small bodies of water.

If they're the same kind of bird then some may just be juvenile.

These are sizable birds, huh? If so, I've seen and wondered about the same thing at the pond on the corner of Siegen and Highland.
