Male Scrub-Jay defending nest

This evening I set up a step-ladder so I could take a photo of the Scrub-Jay nestlings. Mom left the nest with one alarm call, and Dad was there in a second. And he was not about to back down, even when my camera was 8 inches from the end of his beak. So I didn't push it, but did get a photo of what I think are five chicks. Two eggs must not have hatched.
