Red-shouldered Hawk (nestling)

As the leaves fill in more on the trees in my backyard, it's getting harder to get my camera to focus on the RSH nest in my backyard. Despite the cover, I am seeing lots more blurry white movements in the nest and can tell it's getting bigger. I still can't tell if there's more than one nestling as I never see more than one little eyeball peeping at me through the pine needles in the nest at any given time.
