Mme. Owl stopped by the nest box at 6:04 AM CST to do a little nest site prep. That consists, as usual, of kicking around the bedding material to make a depression for the eggs she’ll eventually lay. Another means to the same end, not seen here, is for the female to push the bedding material around using her breast like the blade of a bulldozer. That behavior, however, may be reserved for looser material than that currently present in the nest box.
The material in the nest box, BTW, is what was left after last season's breeding. I haven't made any effort to replace it. One reason is laziness; egg laying shouldn't begin in these parts until March, and the last time I went looking to buy wood shavings (as used in hamster cages, for instance) all I could find was something resembling cat litter. The other reason is that I need to move the nest box to a living tree before nesting commences (a project I admit to putting off due to the fact that it's going to be a major pain in the ass), and leaving the old bedding material, rich with familiar owlet smells, in the box should help reassure the adult owls that this is the same nest they've trusted for who-knows-how-long, just miraculously relocated. I have no evidence that that will be considered significant by the owls, but it seems like a reasonable possibility with no downside.
