I have 3
apple trees and 1 crab
apple tree near each other in my
yard. In the fall, migratory robins will eat the crab apples - I have seen probably 40 birds in my one small tree. If I leave some apples on the trees long
enough for them to start to get soft, the robins & starlings will eat the apples as well. But they only eat what I did not already pick. I have never had a bird eat off an apple that I was planning to harvest.
We also used to have a lot of Himalayan (invasive) blackberries in our yard, and the birds ate those once they started getting soft.
I have recently planted a lot of blueberries and other berries. I am planning to put bird netting over those if the birds get to them before I do.
A
permie approach might be to put some Cooper's Hawk roosts near your berries (if you have any Cooper's Hawks). But you will also lose some birds to the hawk.
Another idea might be to plant some fruit/berry which ripens earlier than your fruit/berries, since in my
experience the birds go for fruit that is soft. On the other hand that just might attract the whole flock to your yard?
For
insect control, I would also add bats and swifts to your list. Those are both in trouble now, especially bats - they are in
HUGE trouble and many of our
bat species will likely go extinct. If you have any bats in your area, there is a good chance you can attract them to your yard with a bat house. For swifts, if you have a large chimney, remove the cap when the swifts are around.
