I had entered "11" for Pine Siskins on Saturday and "7" for Sunday, and both times I was asked to confirm that I indeed had seen this species.
My guess is a lot of GBBC respondents in North Jersey will have to confirm "Pine Siskins" as well, and in far greater numbesr than I had.
I saw a few reports of more than 100 on e-mail list posts.
It only takes a couple of minutes to enter an observation report, BTW. Link is here.
