I went back to the nest today and got my first Blue Jay attack. They can actually inflict a bit of terror onto a subject. I wasn't expecting it. I moved in a little bit faster than usual. Because of the heat and the size of the babies (not much room in the nest) the mother (or father) was out of the nest, but up in the next branch (close by). Usually the mother (or father) is in the nest and flies off when I approach. Before the parent scattered, they did an aerial assault on my head.

From the photos, it is actually hard to see any change, but they are much bigger now. None of them opened their eyes while I was there, they remained sleeping. Perhaps they are used to me.

Instead of a wider "here's the crew" shot, I opted for this macro of the beak/nostril. At 100% crop, you can see the tiny feathers inside it.
