I visited a few Louisiana rookeries in late April. I thought I'd share some of the behavior I observed.
Image #1
These are Snowy Egrets after a tussle for territory. No real harm done except the pond was being patrolled by a 12 foot alligator - the bird did not stay in the water long.
Image #2
This is a Roseate Spoonbill bringing a stick back the nest. I didn't see this behavior often from the Roseates as they could be seen stealing the sticks from smaller birds' nests such as Little Blue Herons and Cattle Egrets.

The birds would sometimes spot sticks in the water and make a go for it. This Great Egret tried for this large stick but dropped it before making it to the nest.
Image #4
Great Egret feeding young. This image shows two of the chicks which appear well fed. Not pictured is a hidden third chick in the nest which appears malnourished. My understanding is that it is unusual for more than two chicks to survive.
Image #5
Here is a Cormorant bringing in a branch. I read that their nest is constructed first of bare twigs then leafy branches so this bird's nest must be near completion.
