Hello, Scott from Yakima and everybody else!
Yesterday I noted that I emailed Cornell inquiring about the peanut-butter issue and birds, and Scott from Yakima wanted to know what the answer was. The reason I did not post the answer is that I have only just emailed them the question and haven't received an answer yet. If they do respond, I will certainly post their reply.
Best,
Christina
