I just posted atlas data for house finches on the blog. This is another of those common species that has not been reported in a lot of blocks, and confirmed in surprisingly few. Although this species has suffered somewhat from disease, my guess is that the apparent discrepancy is largely due to under-reporting, rather than decline, so I've added some tips on how to search for and confirm the species: http://ctbirdatlas.org/blog/index.php/2021/06/11/confirming-house-finches/ Chris Chris Elphick @ssts Storrs, CT elphick@sbcglobal.net
