Maybe I'll trigger my own quantum vortex by writing this comment but you prompted me to look at my own records. In the 13 years that we've lived in our current property I've kept my garden list (birds have to be in or seen or heard from the garden is the general rule). There are 10 species that have only been logged once. Of those 4 are raptors and are probably fly-bys or where riding thermals nearby, another 3 are shore birds and almost certainly fly-bys (we're not that far from the shore), 1 green woodpecker - unusual but not rare, and 2 - chaffinch and coal tit, are very common birds here and I see them all the time elsewhere. So maybe my quantum vortex might suck in some of those common birds that never seem to show up?

Indeed they might! Start listing and thinking about them and, most importantly, keep your eyes on the yard! Let me know!
