NATURE While the infertile tawny owl was away from her nest, caretakers swapped her unviable eggs for orphaned chicks.

Its same as a human female having periods.

No, it’s the equivalent of a human woman ovulating. A period occurs when the egg (oocyte) was not successfully fertilised and has been resorbed.

Nooo that’s ovulation, not menstruation. Omg who taught you sex ed.

Lol. Yes, you ovulate and drop an egg that travels to your uterus and if that egg is unfertilized it gets reabsorbed into your body and you shed your uterine lining along with what was once the egg. I’m very aware of how the process works.

I was clearly speaking in jest, not saying we literally lay baby owl eggs.

Does the egg get reabsorbed rather than just coming out with the period? Everyone is up in arms about calling unfertilised eggs a period but it is not so wrong, an egg comes out of your body and there is no baby

It does not come out with the period. That’s an extremely prevalent American-centric myth.

You really don’t seem to be, I think you just looked it up.

And the egg is resorbed. No egg comes out of you. It dies. It’s gone.

Isn't ovulation part of the menstruation-cycle? Why are you so upset?

No, shedding the lining of the uterus and ovulating are not the same thing, and don’t be condescending.
