The most effective solution I found for pigeons (although I haven't built this so can't compare...) is feeding them at regular times. It doesn't even have to be a lot. They're smart enough to know I come out around 0830 to give them some seed, and then they fly away for the rest of the day because no more food is coming. Sometimes when new babies appear, it takes a couple of weeks for them to copy the pattern though.

If you live in an urban area, please don't do this. Pigeons are pests. They carry diseases. Their shit is toxic and can cause serious respiratory issues.
