I learned something new about the iPhone 7+ camera(s). Smartphones are handy in that you can sometimes get them into spaces where an IL camera won't fit, but the "selfie" camera on the screen side of the phone doesn't focus as close as the main camera modules on the back. I couldn't see to compose this picture any other way than by using the "selfie" camera, and it wouldn't focus on the eggs. The nest is right under the eaves and I couldn't get the phone far enough away.
These eggs have apparently been abandoned, which is making me unaccountably sad, probably because it echoes the rest of the sadness in my life. A mother robin raised an earlier brood in my robin condos under the pavilion (there are now three nests, which are re-used year after year), and I even got to see one of the fledglings make its first flight—a first for me—because I dropped something by mistake and scared the little guy right out of the nest. There has since been a second batch—robins will raise up to three batches of eggs per season—but the mother of the second batch seemed more nervous than the others, and never entirely got used to me and the dogs like the others did.
Then one day she wasn't at her nest, nor the next day either, and I became concerned. The third day I saw a robin standing on the edge of the nest and I thought, good, she's back! But then two more days went by with no signs of life. That's when I decided to stand on a stool and, carefully, not touching anything, use the phone camera to spy into the nest; I wanted to see if some predator had gotten the eggs and they were gone.
As you can see, the camera showed the eggs still there. But it's been two days now since the photo and I haven't seen any further signs of the mother.
It's such an enormous investment of effort to raise a brood of chicks that robin parents will abandon the task if there isn't a reasonable chance of success. If the mother is killed, of course, the eggs are doomed. The male can't incubate the eggs and doesn't know the other necessary behaviors such as turning the eggs. But the mother will often abandon the eggs if the male is killed, too—one website notes that the male performs "finishing school" for the fledglings, teaching them how to gather food and other worldly skills. Without him, the youngsters' chances of survival go way down.
What I suspect happened in this case is that the mother was killed and the bird I saw hanging around the nest on the third day was the male. But I'm no ornithologist, and of course I have no way of investigating or knowing what became of this poor family. Whatever happened, it appears that the eggs in this blurry picture are never going to become birds to add to the ever-diminishing avian population, alas.
