The Global Bird Collision Mapper (GBCM) is an online geo-mapping tool designed for registered users to report the locations of bird-building collisions across the globe. One can enter these records from their laptop, tablet or mobile device. The details of each report can be seen by anyone who visits GBCM.

The Global Bird Collision Mapper is an international bird collision database designed to help better understand where and to what degree collisions are occurring. Your bird collision records will not only help demonstrate the magnitude of the problem, but they will help inspire further development of effective preventative measures and standards designed to protect bird species.

To enter a collision record, you need to start by creating an account. To the right of the Mapper header, there is an account icon that will pull up the login window. At the bottom of the login window is the register option. Once you have entered your account information, you will need to verify your email address. Once you are logged on to your BirdSafe® Mapper account, you can enter a collision report under the menu icon.

You are not required to identify individual bird species to report collisions. In fact, we discourage entering a species name unless you are skilled at bird identification. We do however encourage including a photo of the bird for the purpose of possible identification at a later time.

If you wish to familiarize yourself with bird species to aid with identification, there are several excellent bird identification guides available for purchase at your local bookstore. The Peterson Field Guide to the Birds of North America and National Geographic Field Guide to the Birds of North America are both good guides. In addition, the Cornell Lab of Ornithology has a phone app called Merlin Bird ID, which is able to identify the possible species of a bird with a photo.

Explore different basemaps when you can’t locate a building on the default topographic map. The satellite map tends to be the most up-to-date map. The option for basemaps can be found in the navigation dropdown.

To access your collision reports, you can either locate your report on the map, or search for your entries under the “Explore the Data” under the menu icon. Enter your username into the “From a specific observer” bar. Once you have pressed enter, your reports will show up on the map and you can either click on them individually or scroll through them in the total reports.

Currently you can only edit one of your entries within 7 days of creating it. Once you have found the specific report you want to edit on the map, you can select the report and click the small edit button in the bottom left corner.

If you accidentally made an entry and want it deleted, simply email mapper@flap.org with the details of the specific report and we will delete the record for you.

To create a group in the Bird Collision Mapper, simply fill out the group request form at the bottom our GBR Manual and email it to mapper@flap.org. We will create the group and add members for you. Once individuals are registered as part of a group, they can submit reports independently or as a group entry. Make sure to indicate you want to create a group in the subject line of your email.

You have up to 1 week (7 days) to modify a collision record after initial entry.

To ensure the accuracy of a collision location, locate the building on the map where you found the bird. This can be done in one of two methods:

  • enter the address of the building into the Find address or place box in the upper right-hand corner of your screen.


  • click the Use my location icon at the top left-hand corner of the Report Collision form. Click this icon 2 or 3 times to assure accuracy.

Once you have located the building on the map, identify the side of the building where the bird was found and zoom in to a closer magnification before clicking on the map to enter you record.

You will find that pressing the ‘Find my location’ icon isn’t always accurate. To ensure you are entering a collision record at the correct location, consider entering the building address into the ‘Find address or place’ field located in the GBCM header.

When registering as a GBCM user, it can take up to 20 minutes to receive a verification code. Be sure to check your junk mail if the verification code doesn’t arrive.

You can request to be part of a group by emailing mapper@flap.org and providing your account name and the name of the group you are trying to join. We will add you to that group and you will then be able to add entries with that group.

Yes! Once you have an account, you can be part of multiple groups.

The side of a building is important because a building can have multiple sides and facades. By indicating which side of the building the bird struck, you are helping to identify the highest collision risk areas for birds.

Yes, birds matter. Birds provide a critical link in native ecosystems. They pollinate plants, distribute seeds, and eat billions of insects every year. These behaviors help to maintain fertile agricultural land, healthy wetlands and lush forests. Birds play a vital role in the ecological and biological interdependent processes that are essential to life itself.

Birds also provide an accessible connection to the natural world, especially for urbanites. It is hard to imagine a day without the rejuvenating sound of bird song. Their beautiful bird song, remarkable feathers and interesting flight patterns immeasurably enrich our lives, inspiring design, architecture, culture, art, music and poetry.

Equally important is the contribution birding is to local economies. The last survey, carried out by Statistics Canada, on behalf of the Canadian Wildlife Service, indicated 14.5 million Canadians participated in wild-life-related recreation activities. In a 2011 US Fish and Wildlife survey on birding in the United States, 71.8 million birders spent $17.3 billion on trip expenditures and $27.2 billion on equipment.

Some tiny birds, such as wrens and warblers, look like baby birds even though they are mature. If you find a bird sitting under a window and it does not move when you approach, most likely the bird is an adult bird that has hit the window. Follow these instructions if you find an injured bird.

If you find a featherless baby bird, and you know where the nest is, place the baby bird back in the nest. The parent birds will not smell your scent and reject the bird. If you cannot find the nest, make one out of a small basket or flowerpot lined with leaves or dry grass. Place the substitute nest close to the area where you found the baby bird.

If the baby bird is feathered and has just left the nest, it may be on the ground waiting for its parents. The best thing to do is leave the bird for the parents to care for and feed. If you believe the bird is in danger from roaming cats or other predators, place it high up on a tree branch where it will be safe. If you are still concerned (perhaps the parents have not returned for a long time) contact your local wildlife rehabilitation facility for advice.

If you find an injured bird, follow these instructions and immediately contact your local wildlife rehabilitation facility. Report dead or injured birds on the Global Bird Collision Mapper.

Thank you for considering a rewarding volunteer opportunity that helps keep migratory birds safe. We rely on volunteers for many tasks, including event support; in-field bird rescue patrols; driving injured birds to wildlife rehabilitation centres; writing services; fundraising campaigns; translation; database; and, office work, to name a few. Please contact our volunteer program coordinator, Paloma Plant, who can coordinate an assignment that suits your interests and skills; pplant@flap.org or call 416-366-3527.

Yes. The extent of training depends on your assignment with FLAP Canada.

Birds are much more likely to contract diseases from humans than the other way around. For this reason, and to protect yourself from any remote health risk, we suggest that you wear hand protection such as latex or vinyl gloves, and wash your hands before and after handling birds. This is simply good practice when handling any wildlife or unknown plant material or matter the bird may have been exposed to. Refer to Public Health Agency of Canada guidance in this matter.

The risk of contracting West Nile Virus from birds is minute. The best way to protect against West Nile Virus is to protect against mosquitoes. Bites from infected mosquitoes are the main transmission route of West Nile Virus to humans. Even then, the chances of you becoming extremely ill from the bite of an infected mosquito are extremely small: less than 1%.

You can always use gloves when handling live or dead birds, and follow-up with thorough hand washing or the use of hand sanitizer. This is simply good practice whenever handling birds or any other wildlife or unknown plant material or matter the bird may have been exposed to. For information and up-to-date facts about West Nile Virus, visit Public Health Agency of Canada.

According to the Ontario Ministry of Health and Long-term Care (MOHLTC) “the HPA1, H5N1 virus has not been detected in Canada, and at this time, there is no reason to believe that backyard birds or wild birds are a threat to the public.”

Avian Flu infections in humans are almost all traceable to direct contact with infected poultry, surfaces contaminated by poultry, or consumption of infected poultry. Those infected have most often been working in close contact with infected poultry in unsanitary conditions.

Injured or dead birds found around buildings most likely did not succumb to Avian Flu or any other infectious diseases and pose no threat to humans.

Migratory birds live in forests, meadows or wetlands, and do not understand the concept of glass. To a migratory bird, glass is an invisible and dangerous obstacle. They see the landscape reflected in windows and mirrored building exteriors and mistake the reflection for shelter. Or birds see beyond the glass to interior potted plants or trees inside the building. Where windows meet at the corners, or line up with each other front and back (i.e., glass walkways, solariums, greenhouses) birds perceive clear passage and try to fly through to the trees they see on the other side.

Any reflective or transparent surface used in construction—from glass on bus shelters, to mirrored exteriors on high-rise buildings—can be the site of fatal bird collisions.

Most species of songbirds migrate at night. They rely, in part, on the moon and the constellations to guide them along their migration route. The overnight lighting used in dense urban areas confuses migratory birds, and especially on foggy or rainy nights when cloud cover is low. Under these conditions, birds migrate at lower altitudes and are drawn to lights shining from office towers and other structures. Where spotlights are used to illuminate a building, birds fly “into” the beams of light and are reluctant to fly back out into the darkness. Often, they collide with the buildings or drop to the ground from exhaustion.

When day breaks, birds that managed to survive the night-time lighting hazards find themselves trapped in a maze of tall buildings with reflective surfaces. It is extremely difficult for migratory birds to escape this maze without striking windows and building exteriors, often with fatal results.

Birds hit windows anywhere there is glass, and glass is everywhereIn Canada alone, glass claims the lives of around 25 million birds every year. In the United States, that number may be closer to a billion birds lost each year. We can only expect these numbers to increase as our cities grow and our fixation with glass buildings continues, unless we act now. 

Collisions with buildings are a leading cause of migratory bird death. Any human-built structure that incorporates glass or reflective building material into the design can be the site of bird collisions during the day; including, houses, office towers, transit shelters, car windows, greenhouses, solariums, walkways, and any other structures where windows and/or reflective surfaces are present. At night, transmission towers, monuments, lighthouses, oil rigs – virtually any tall illuminated structure can be responsible for bird deaths.

The number of bird fatalities due to collisions with wind turbines sits well below the number of bird fatalities from collisions with buildings; however, as more wind turbines are built, more birds are killed by them.

The National Wind Coordinating Collaborative recognizes two types of impact on birds at wind facilities: direct mortality from collisions, and indirect impact from habitat disruption, habitat avoidance, habitat abandonment and the changes in instinctive bird behaviours due to the presence of wind turbines. Most of the bird fatalities are songbirds, but raptors are also killed when wind turbines are erected in open areas where these birds hunt for prey.

The onset of both spring and fall migration can fluctuate mildly each year. Generally, in the Great Lakes area, spring migration begins in mid-March and continues until the beginning of June. Fall migration in this area begins in early August and continues until mid-November.

FLAP Canada offers a special migration alert service for property managers in commercial and institutional sectors. Learn more and subscribe here.

There are many ways to make your workplace safer for birds! Visit birdsafe.ca for everything you need to know about bird-safe best practices, and learn how FLAP can support you in making your workplace bird-safe.

If birds are colliding with the building(s) where you work, contact your building owner or property/facilities manager to let them know. As an employee or tenant of the building, you can help with night-time collision prevention by turning off lights at night except for those necessary for safety. Some tenants have chosen to pursue daytime cleaning. Use a desk lamp at your work station when working into the evening hours, and keep blinds and/or curtains closed. During the day, keep blinds and/or curtains slightly closed and move interior plants away from glass. You can also encourage your building owner or property manager to seek advice or information from FLAP Canada, bird-safe experts, at 416-366-3527 or email birdsafe@flap.org.

Please follow these steps and immediately contact your local wildlife rehabilitation facility.

The key to stopping birds from flying into your windows is to make the entire window look like a barrier to birds. You can do this by applying dense patterns of markings (small dots, squares, lines, etc.) to the outside of your window. There are many affordable and attractive options to choose from that won’t ruin your view. Learn how to make your windows bird-safe.

No. A single black hawk silhouette affixed to a window is not effective at all in deterring birds from colliding with a window. The shape of a window decal is unimportant in preventing birds from hitting windows; it is the use of multiple window decals in any shape or colour, applied in a dense pattern that helps make windows visible to birds. Learn how to effectively prevent birds from hitting windows.

According to a 2013 Environment Canada research study, cats kill more than 100 million birds each year in Canada, making them the most significant human-related bird mortality factor.

Keeping your cat indoors saves birds and small wild animals, but it also protects your cat from harm. Veterinarians, humane societies and animal protection agencies all strongly advocate keeping your cat indoors. An outside cat faces many dangers including: getting hit by moving vehicles, getting lost, being stolen or poisoned, contracting infectious or fatal diseases, and getting attacked by other cats, dogs or wild animals. Outdoor cats have a considerably shortened lifespan compared to indoor cats.

The ideal location for a bird feeder is right up against the window surface, or no more than 0.5 meter (1.5 feet) from the window. This positioning significantly reduces the likelihood of injury should a bird hit the window before or after feeding. The 0.5 meter or less distance does not give birds the opportunity to build up any momentum when they fly from the feeder, but it gives you the opportunity to enjoy watching birds up close.

Many people become alarmed or annoyed when a bird taps or pecks at their window in the spring. When a bird pecks at your window, it is fighting what it perceives to be an intruder. The bird doesn’t understand that it is attacking its own reflection; it is simply defending its territory. This territorial reaction may be so strong that the bird exhausts itself or sustains mild abrasions, but the behaviour usually doesn’t result in fatal injury. Both males and females birds may exhibit this behaviour, especially those species that nest close to our homes such as American Robins, Northern Cardinals and Chipping Sparrows. Here are some tips on how to stop birds from tapping at their reflection in your window:

  • Cover the outside of your window with a window screen or fabric to obscure the bird’s reflection.
  • Shine a lamp out through the window during the day to create a bright glare and mute reflection.
  • Cover the outside of your window with perforated window film such as CollidEscape.
