Well,just maybe it's fortune and love or anything else good for that matter.
Also hope that they will stay, at least until the babies can fly, but birds don't usually desert their nests, unless there is real danger about.
Sounds of machinery close by is one of them.
No way that you can place a temporary board there?
I plugged the hole and will leave that corner til the very last moment possible. The tradie we have is on a very loose schedule, so hopefully in a couple weeks they will have cleared out.
Great and glad that you are a "Mensch" for leaving them alone.
Yeah, they will fly in a while and let's hope that the parents will return next year!
