Most conflicts with pigeons can be tied at one point or another to feeding, intentionally or otherwise.
Avoid attracting pigeons by cleaning up leftover food scraps and crumbs. Innolytics, LLC.
Pigeons get fed plenty of handouts and garbage, but there are also well-intentioned pigeon lovers who regularly feed the birds. This does the pigeons more harm than good as the pigeons begin to gather in large numbers, often leading to inhumane and ineffective attempts to reduce their numbers.
When such troubles arise, the best thing for the birds is to reduce feeding gradually over several weeks. The flock will gradually disperse until the remaining number of birds matches what the area can naturally support.
Even when not feeding on purpose, we humans are messy, leaving leftovers and dropped crumbs everywhere. Pigeons hang around town squares, public parks, and other trafficked areas to help themselves to what we leave behind, especially when convenient roosting and nesting sites are nearby. To discourage pigeons from gathering, food attractants need to be cleaned up regularly.
In suburban neighbourhoods, too, homeowners may mistakenly feed pigeons or they may be providing food for pigeons inadvertently when feeding their backyard birds by tossing seed on the ground, rather than putting it in bird-feeders. To discourage pigeons visiting your yard, change the type, amount, and timing of feeding. If most of the pigeons fail to move elsewhere, you’ll need to stop feeding all birds for a couple weeks. (Don’t worry; the birds won’t starve.) When you resume feeding, only put out seed in bird-feeders and keep the ground below them cleaned up.
