It's a bird. Put netting over the tomatoes propped high enough over the tomatoes so bird can't reach in the get them, or put row cover over the tomatoes. I used row cover in earlier months when that bunch of tomatoes was ripening because the birds did do that. They only did it once, because I covered them after that.
Don't you hate it when the tomato has been ruined like that? I didn't have an opinion about birds and squirrels and insects until I started this gardening stuff and now I have a hate list.
I know what you mean about “liking” all of nature. Hubby keeps telling me that they need food too. But up went the cover. I just dislike squash bugs and fireants.
