Yes,
and maybe it has something to do with more people hanging feeders
and maybe it has always been this way but now with computers zapping info. around the world in a nano second more people (& researchers) are being made aware of it
and maybe it's because there are greater #'s of seniors than ever before who sit around watching & notice nature things
and maybe it's any of these things you & I mentioned & maybe it's none & maybe these things have been considered in the research & perhaps not
and maybe i'm NUTZ!
