So, after last night's storm, I found a Robin's egg, apparently bounced out during the wind. It was broken - the break was on the bottom, where you couldn't see it until you picked it up.

It was dead when I found it, the head-end cracked wide open, and the tiny right wing sticking out. Despite the blood still being liquid and the baby still flexible, it was stone cold, and entirely dead.

In my capacity as Temporary Acting King of the Baby Birds, I appointed myself Temporary Acting Coroner of the Baby Birds, and set up office on the front step. Here the top of the egg is off. That's rather a lot of blood from such a tiny baby. I really should have weighed him in the shell, but didn't think of it in time.

You have a really good view of the chorion here, which is how the baby exchanges blood gases while he's in the shell. The wide end of the egg is the head end, and there's a sort of air space there for the chorion to interface with the air.

The baby bird fully removed from the shell, with all the protective sacs removed. You can see how much of the yolk sac remains to be absorbed. He was two or three days from hatching, I think.

Note the internal bleeding just behind the eye. I have to think that happened in the tumble. He hit hard enough to break open the shell, after all. Even if I'd been there at the time, I really doubt that he could have been saved. Sad, but some things are like that.

Gruesome, but educational as well, especially if you've never seen one open.

So back on the 12th of March, I took a walk around mom's property to deal with fallen sticks and limbs (to the brushpile with them!), and to generally check for damage, as there'd been serious winds the previous few days. Sticks everywhere, of course, and debris (I recovered one of her basement window covers from way out in the neighbor's corn field), but I also found the wreckage of the woodpeckers' home from the big maple:

Sad, but much better to have it happen in the early spring than later on when it's full of babies.


I also found, of all things, a starling's egg:

A starling's egg.

There's dried mucous on the surface, and it rained the night before, so I'm guessing it was laid that morning. It was only about 25 feet from the cake feeder too, so couldn't have laid out too long without one of the woodpeckers finding and eating it. Starlings, in particular, are known to sometimes lay an egg on the ground if the nest isn't ready, and I'm guessing that's what happened here. I'm wondering if the high winds interfered with completing the nest, so it wasn't ready when expected.

I wonder too what the hen's emotions were at having to abandon her egg that way? I know that domestic chickens suffer real stress if they have to lay an egg in the "wrong" place. Sad event all around, although a fascinating thing to find. It massed only 6.0g. The baby would have weighed less than that, even, since that includes the shell. And in only about two weeks after hatching, it would have grown into a young bird, able to fly. That continues to amaze me.

Given that she was starting to lay on the 12th, I think it's reasonable to expect babies by middle of next week, at the latest. I haven't a clue where her nest is, though.

Why does the Rose of Lancaster appear on the Norwegian Intelligence Service's arms? The ravens are quite obviously Hugin and Munin, (and just *so* satisfyingly appropriate), but why the rose? Norway had a single Plantagenet queen back around 1400, it seems, but that's surely not it. It's not in the national arms, nor in the military's (of which Intelligence is a part) either.

So, I needed eggs. I had no fewer than four separate brands of free-range eggs from which to choose. Most of the rest were "cage free". The only ones where the packaging didn't give some assurance of the chickens' living conditions were the big semi-generic 100 egg institutional packages. And this was at Giant Eagle. Only a few years back, the only way you could get even cage free eggs was at places like Whole Foods or Fresh Thyme, or by driving out into the country to buy them directly. I have to conclude that it's market pressure at work crowding out the battery-hen eggs. That's reassuring.
