Provide a birdbath, the birds are after moisture .
They don't even touch my tomatoes,but I keep h2o in my bird bath at all times,let it dry out and they will be eating them.
No bird flash tape or CDs,nothing.
I have birdbaths and 5 gallon buckets of water sitting everywhere in my yard. I also keep a buffet of seed for birds throughout the yard. The birds lack nothing. Except maybe tomatoes. Now I have supplied that for them. I had to keep the worm bin covered because I catch them in there eating my worms. At times, my yard is a wildlife refuge. There are plenty of grocery stores around me. If I am supposed to feed the animals than so be it.
