Budgie Breeding-A Euphemistic Yet Biological Update

I have received a few requests to not be vulgar on this blog, so, I am using Euphemisms from this point forward as much as possible. However, if anyone wants a euphemism to biology translational post, I'd be pleased to oblige upon request.

This morning, both parents were out of the nest box. Mary ann did her "toiletting" Her "butt" was triangulated in appearance. The tail region was large. Sutcliffe was feeling "romantic" and attempted/succeeded in mating activity.

This is of interest, because there are already two eggs. Therefore, not all eggs are fertilized, one would surmise from this, at the same time. Only two eggs were seen so far. Last time, she laid 4 eggs, three hatched, only one survived. I don't know if there are unfertilized eggs laid when there is a cock around, or if the other simply didn't make it at an earlier point in the brooding.

Mary ann and Sutcliffe have also begun rigorous housecleaning. Mary ann "toilets" once a day (always in the same spot: to me, that is interesting). However, Sutcliffe occasionally "goes" in the nest box. This is removed promptly, as are some feathers (others remain, not clear how these are chosen-perhaps soiled featehrs are removed?).
