The birds have been pecking at the tomatoes just when they're about ready to be picked. Smart birds.
BUT I'm playing with coffee filter hats, slitting them from the side to the middle and then slipping them over those tomatoes that are almost ripe. These are some Rio Grandes. I picked a few but then covered the ones getting as red as the ones that were pecked.
Maybe if the birds can't see ripening tomatoes they'll leave them alone. Curiously, they don't mess with the yellow/orange ones. Could it be they think they're not ripe? Bwaaaaahahahahahah! FOOLED YOU!
