Birds
ADC employs species- and situation- specific bird deterrents to minimize the nuisance and conflict potential caused by birds. The general aims of our approaches go beyond temporarily removing or chase away problem birds, but to modify the attractiveness of human structures and areas as habitats for birds, causing them to spend their time elsewhere.
Canada Goose
Branta canadensis
The Canada goose is a game bird protected outside of the hunting season. They may cause crop and horticultural damage when foraging in flocks, as well as occupy parks, golf courses and landscaping. Besides being aggressive to humans, guano left by large flocks can be a nuisance.
Pigeons
Columba livia
Pigeons are very common in urban areas and classified as a nuisance species. They congregate in urban and agricultural areas for roosting and nesting, feeding on refuse, spilled grains and insects. Their droppings carry multiple diseases and parasites transmittable to humans, as well as deface and accelerate the deterioration of buildings and structures.
Corvids
Family Corvidae
Corvids, including the Raven (Corvus corax), American Crow (Corvus brachyrhynchos), and Black-billed Magpie (Pica hudsonia) and are intelligent social bird species common throughout Alberta. They are not protected on private lands. They pose no danger to humans, although when they scavenge human waste and garbage, they may spread refuse around that may attract other scavengers. Large concentrations of these birds may pose a nuisance from their noise and droppings.
Other birds with conflict potential
Starlings (Sturnus vulgaris) and house sparrows (Passer domesticus) are also a common nuisance bird species congregating in residential, industrial and municipal structures. Large flocks may cause crop damage from foraging. Their droppings carry diseases and parasites transmittable to humans, as well as deface buildings and plug air vents, as do their nests.

Gulls, of which there are many species in alberta, share many of the nuisance potential as corvids. They are protected.

Birds of prey, including eagles, hawks and owls, may attack poultry, exotic birds and small domestic pets for food. They are fairly common and protected as well.
