every year i plant tomatoes and peppers i loose a bunch. i thought it was rabbits for years untill i caught the culprits. black birds pinch them off at the stems and fly away with the plant. i had been putting a chicken wire fence around it but still loosing plants. thats when i relized that the predators were coming in over the fence not through it. last year i had to totally inclose the garden with chicken wire and drape a bird net over the entire thing. i seen the birds bouncing off it at times. i tried metal pie pans didn't do much. and a fake owl and blow up snake. anyone have anymore tips.
