Pigeons and doves have short necks and stout bodies with short, slender bills. They have been found to be quite intelligent, being able to differentiate between different words and even have a concept of space and time. They can remember the location of their nest from 2,090 kilometres away. This intelligence can make them difficult to get rid of.Pigeons can be very frustrating. Any home or business owner that has cleaned up pigeon droppings or had pigeons nest on their roof, balcony or attic will agree. Not only are pigeons a nuisance, but their waste carries dangerous diseases, presenting a health risk to you and your family.
