The male put on quite a show bringing sticks to show the white female. She ignored him a lot, but when he decided he has collected a good stick, he flew off with it back into the mangroves, presumably to add to a nest.

There was also a juvenile reddish egret, and a second adult further down the beach with the mix of other shore birds. What a great day for reddish egrets!
