These three chicks really look like Anhingas now, with the classic black and white “piano key” feathers on their wings.
Like the wading bird chicks in nearby nests these older chicks are spending more time interacting with each other as they wait for the parents to bring food. These three were so busy they didn’t even notice when one of the parents was on its approach.

I don’t know what made her abort her landing, but she circled around the tree for a second try and successful touch down.
