Pigeons are know to make the venture from there closet habitat in Vancouver to Squamish quite regularly and have even been seen in Whistler. Originally found in Europe circa middle ages, these winged old feather factories they like to get their height on in Toronto or New York style windowsills roofs, eves, steeples and other man made structures.
They mainly eat seeds and grains, even insects when provided intentionally, and believe it or not domestic cats are the main urban predators, but opossums, raccoons, foxes, weasels, and rats also eat pigeons (when they can access the nest).
