Hi,
If you were a bird, and would find water and food ... You would use both, and not just the fresh water.
Here, in July and August, we have migratory birds passing by and I get more damages by then.
Now in September, they reached Africa, and the figs are left almost alone.
I just had to tell the house sparrows to go somewhere else. If I had given them water they would have stayed and go after the figs.
"Don't create an honey pot, or you'll get bears" :) , is my way of thinking.
Keep the orchard clean, remove (bury or take far away) every spoiled fruit ASAP; Remove hides ( hedge under control, grass and weeds short) ; don't let any source of "pleasure" there and you'll be bothered less.
Then, critters coming in need to be scared away (birds) or removed (rodents) .
What I most hate is that they don't even finish the first fruit .. They taste them all and just eat half or less of each ...
Are the birds looking for the seeds ?, for the flesh ? , for the humidity in the fruits ? ... Well, all of them , I think.
I have water in several barrels, and they still peck on the figs ...
