The Decoy Effect: Why Geese Flocks Grow During Migration Season

Geese are highly social birds, especially during migration. They depend on each other to keep an eye out for predators and to let each other know when danger has been spotted. This behavior is something that hunters have been exploiting for centuries by placing decoys in the hunting zone to draw migrating geese. Geese flying overhead see the decoys and register the area as safe to occupy.

While it may provide hunters with an advantage, this effect can be a challenge for goose management teams and the properties they serve. Even if your property only has a few geese on site, the sight of them safely enjoying your hospitality will draw in migrating flocks overhead. Geese have excellent eyesight. Even at high altitudes they can spot the areas their fellow travelers have chosen to occupy and in as little as a couple of hours, a small gathering can turn into a party of hundreds.

How to Counteract the Decoy Effect During Migration Season

It’s an intimidating prospect for property owners. But our team of experts know how to make the Decoy Effect work as well for bird management as it does for hunters. Just as geese can see a safe place where their buddies are congregating, they are also quick to notice a site other geese are avoiding. A goose-free property significantly reduces your chance of being bombarded by migrating flocks because geese will steer clear – recognizing that it may be uninhabited for a good reason. That’s why our team works hard to ensure that our deterrent efforts leave no goose behind to attract the thousands migrating overhead.

Starting your goose deterrent service before migration begins allows us to make sure that resident geese will stay away and won’t be there to entice the enormous flocks looking for a stopover on their way south.

Of course, even an empty property can draw migrating geese if it contains the right combination of food, shade, open water and other goose amenities. It is important to stay vigilant throughout migration season to make sure that flocks keep moving on.

Bird Adaptation to Urban Life: An Unwelcomed Stay

Did you know that dinosaurs never went extinct? That’s right, we still have dinosaurs today! The first bird, archaeopteryx, evolved over 150 million years ago from dinosaurs closely related to the infamous velociraptor. Raptors looked very different than they do in the movies. They were much smaller, fully feathered and looked a lot more like birds than reptiles.

Birds are incredibly adaptive. They are the only known descendants of dinosaurs to have survived. They have colonized all continents, traverse the ocean, and thrive in the most extreme of environments. It’s no wonder that some bird species have adapted so well to the urban environments that humans have created.

Human structures create a wide variety of nesting opportunities for many bird species. Cavity and ledge nesters like pigeons, mourning doves, house finches, robins, starlings, and house sparrows find all sorts of nooks and crannies to raise families in. Swallows find our overhangs, loading docks, and bridges irresistible nesting areas. Colony nesters such as ring-billed and herring gulls, and even Canada geese, see our flat commercial and industrial roofs as great spots to nest safely away from ground predators. Green roofs are excellent habitat for many birds and one roof in New York City was found to have 11 different species of birds utilizing the space. Turkey vultures, though they don’t usually nest on buildings, use them to rest and scan for roadkill to feast on. Killdeer build well-camouflaged nests on  gravel pathways. Even the peregrine falcon, the fastest animal on the planet, has made city buildings part of its nesting habitat. Sometimes these nests are welcome and building inhabitants enjoy watching the birds raise their offspring. Often, however, nesting birds are a source of health and safety concerns for building residents.

Water Retention Areas: If you Build Them, Birds Will Come

With buildings and parking lots comes retention areas to collect rainwater and prevent flooding. These ponds and ditches create habitat for many waterbirds and a few species have thrived in these man-made urban environments. Canada geese, which were nearly extinct by the 1960s, have rebounded so profusely they are now considered a nuisance almost everywhere they are found. Mallard ducks, while not a nuisance, can be seen colonizing almost every puddle, pond, and drainage area. Red-winged blackbirds find the cattails, invasive phragmites grass, and other shoreline vegetation to their liking and have become one of the most common urban and suburban birds. Even wild turkeys, once a rare sight, now strut their stuff on urban streets, in back yards, and even in mall parking lots.

Humans have created new food sources for birds too. Bird feeders are popular, even in the city and innovations have allowed even people on upper floors to put bird feeders on their windows. Our food also becomes their food, with litter and food waste a key component in many urban bird diets, especially gulls, starlings, and pigeons. Hand-feeding birds like ducks, geese, and pigeons is also a common pastime for many people, though this is often harmful to birds and the environment and should be discouraged.

Hand-feeding draws in pigeons, geese, ducks, and other birds. It is usually not good for the birds or the environment.

While many migratory bird species are suffering and in decline due to human actions, other birds are thriving and adapting to the new world we are creating around them.
