Here's another one. A lumpy, glowing, white pancake.

Here are a few more quotes from The Sparrowhawk by Ian Newton, 2001.

The young grow quickly: the females gain weight more rapidly, but the males develop more quickly in other respects and are able to fly at 26 days, compared with 30 days in the females. The faster development of the males may help them to survive in the presence of larger sisters. In some nests chicks may die from starvation, and at a later stage, when the parents are away hunting, young may die from chilling during rain storms or from predation. The main predators of well-grown young are Tawny Owls, Goshawks, and Pine Martens, but occasionally young are taken by other Sparrowhawks to feed their own brood.

Once the young have left the nest, they remain in the vicinity for another 3-4 weeks, fed by their parents. At the end of this period the young disperse, and from then on they have to feed themselves. An interesting feature of this post-fledging dispersal is that, in general, females move further than males. The same occurs in some other bird species, including other raptors, and it may serve to reduce the chances of inbreeding.

The average mortality over the first year of life has been estimated at 69% for males and 51% for females. In later life the death rate is lower and more similar between the sexes, at 33% per year for males and 29% per year for females. The greater mortality of males is hard to explain but, being smaller, they are less able to withstand food shortage than females and may also be more vulnerable to predation. Some males are even killed by female Sparrowhawks, for which they make an ideal-sized prey item.

Most Sparrowhawks have a different mate each year and relatively few pairs remain intact from year to year. This is partly because of high mortality and partly because of movements, as some birds change territories from one year to the next. The good territories are much in demand and, in general, individuals tend to move from poor to good territories during the course of their lives.

You can see the unhatched egg. Some were footing it playfully.

An orderly feeding... soon I bet they'll be trying to take the prey item away from the parent.

This is the end of another nice orderly feeding. I'm impressed by the size of the one on the left. She looks as big as Mom, although her tail needs to grow a lot more. On second thought, I think that's Dad that did the feeding.

OK, last edit. I think the chicks are, from left to right: female, female, youngest (?), male.

I think this is the youngest. The first three all looked about the same age and the fourth was just a few days behind them.

The youngsters are now in the fledged but returning to the nest sometimes phase. Earlier I saw three on the nest, then none, now two. The cam image is sideways now, so I rotated my scap.
