Is an anhinga.
It’s a diving bird, so it can’t afford to have the natural oils that keep its feathers from getting wet. Their feathers have to get wet so the bird can dive and swim to catch food, and not bob on the surface like a duck.
Afterwards, they have to perch and spread their wings to dry in the sun.
So they can gracefully soar again like this.
Judy is in Phoenix and I’m here in South Texas finishing up some things, with an inventory of bird pictures in the meantime.
