Something is eating my tomatoes but only when they have started to ripen. See picture please. I don't see this happening on any of the green ones.
There are no bugs or other pests (that I can see).
I initially thought is was raccoons or opossums so I built a frame with chicken wire to keep all rodents out. Well that didn't stop it...whatever it is. Does anyone have any ideas? Possibly birds? Although I have never seen any birds near my garden.
