Webster defines a roost as a place "to settle down for rest or sleep". Therefore, if you have pigeons in the same place every day, it probably represents a roost for them.
Bird roosts come in a variety of different shapes, sizes, and locations. They can be very large or even very small. Pigeons are flocking birds and the flock represents their social unit. Like a school of fish, the birds find comfort in numbers.
Pigeons will often find a location during the course of the day and "loaf". During these times, the birds are not foraging or nesting but simply resting and getting some sun or shade.
Since pigeons are creatures of habit, once they find a location they like, they will return to it regularly. Sometimes, they like a location so much - especially if it has adequate food, water, and shelter - that a roost becomes a nesting site. Like many other birds, pigeons have powerful nest fidelity and will return to the same nest season after season.
Resolving a pigeon roost can require different strategies and no one size fits all solutions. Making a nesting site less attractive can include physical exclusion, although without effective abatement, the birds will simply move around the site.
If a large flock of pigeons is causing problems, consider using a population abatement program as well. OvoControl is a ready-to-use bait, dispensed on flat rooftops with an automatic wildlife feeder. This effective and humane technology is especially useful for managing birds in larger areas without having to resort to poisons or labor-intensive trapping programs.
