Today, they make up more than 60 percent. Read about the epic journeys of migrating birds. Not only do urban and suburban areas offer plenty of food and room to roam, resident geese are also safer from hunters and natural predators. Research shows the resident geese egg clutches are larger and their chicks live longer than those of migrating geese. In southern Michigan, more than half the resident geese tracked during a satellite-monitoring project migrated to Canada when their nests failed.
Another study found that 44 percent of geese in New York, Pennsylvania, and Vermont headed north when they had no young. Sharp tracked one female goose who nested every year in front of the same Toronto office building until it lost its clutch of eggs.
While up north, this bird apparently fell in with a flock of migrators and headed to the Chesapeake Bay region for the winter, where she was shot by a hunter in Maryland. Not only are Canada geese often aggressive, they litter their waste in human-made environments, such as playing fields, boat docks, and golf courses. A goose flock can produce a staggering two-and-a-half tons of poop per year.
To deter the birds, people have tried noisemakers, training dogs to chase them off, and even the Goosinator , a bright-orange, remote-controlled decoy with a fearsome face that scares the birds. But Curtis, who led a study on the effectiveness of hazing geese in New York State , learned that the birds knew every water body within 12 miles.
In some places, notably airports, Canada geese pose a serious danger. He once found a radio-collared female caring for a hundred goslings from many different clutches nesting on an industrial office park roof. He also points out that entire annual life cycle of Canada geese happens within easy view of urban dwellers across North America.

From breeding in the warmer months and hunkering down when the temps drop, Canada geese have a pretty solid system.
The Canada goose is the largest and most widely known goose species in North America. Canada geese have a grey or brown crest, back, and wing feathers with a white or grey underbelly. Their bills, feet, neck, tail, and head are black.
However, only some of the Canada geese in North America migrate. Migrating Canada geese have designated breeding and non-breeding sites that they return to every year. Canada geese that migrate do so twice a year. In September or October, Canada geese fly south to their non-breeding sites to avoid the cold. Geese migrate north to their breeding sites in April, May or Early June. Geese that migrate tend to breed in Canada hence the name.
