As millions of birds are flocking to their wintering grounds, Birds Canada and nine partner organizations have announced the Bird Migration Explorer, a state-of-the-art digital platform that reveals migration data consolidated for 458 bird species found in Canada and the US. The free, interactive platform, currently available in English and Spanish, allows users like you to see the most complete data collected on migratory species in your neighbourhood and where those birds go throughout the year.


The Bird Migration Explorer reveals insights about the journeys of individual species, the connectedness, through migratory birds, of any given location in the hemisphere, and also details how migratory birds encounter 19 different conservation challenges. It includes more than 150,000 movement tracks of 150 species from the Motus Wildlife Tracking System, a program of Birds Canada and collaborators.

For example, the famous “River of Raptors” migration corridor in Veracruz, Mexico, is a hub connecting the extreme northern and southern ends of the globe. The Bird Migration Explorer can also show when each of these species passes through Veracruz or any other location, and the extent to which each of those species overlaps with any number of conservation challenges such as light pollution or power lines along their journeys.

More generally, the Bird Migration Explorer illustrates how countries in the Americas are all connected to each other by migratory birds, underscoring the importance of international cooperation and collaboration in the research and conservation of these species.


Since 1970, North America has lost more than 2.5 billion migratory birds. By highlighting the places birds need – not only during breeding and wintering seasons, but also throughout the migratory periods in between – the Bird Migration Explorer provides a scientific basis for necessary policies and solutions to address these steep declines.

“People have always been curious and amazed by migratory birds and their incredible journeys, but only recently are scientists piecing together the full picture of how these birds travel from one end of the globe to the other,” explains Dr. Jill Deppe, Senior Director of Audubon’s Migratory Bird Initiative, the founding organization of the Bird Migration Explorer. “Migratory birds also need our help—populations are facing steep declines across the board. By consolidating and visualizing these data, the Bird Migration Explorer can teach us more about how to protect these incredible travelers that connect people across the entire hemisphere.”

The Bird Migration Explorer brings together three types of geospatial bird data: abundance data from Cornell Lab of Ornithology’s eBird Status models; connectivity data from the USGS Eastern Ecological Science Center Bird Banding Lab and Bird Genoscape Project; and tracking data from Birds Canada, the Smithsonian Migratory Bird Center and hundreds of researchers from across the globe, who generously contributed their datasets to this project. Audubon scientists and cartographers consolidated these data to create animated and interactive visualizations to bring species migration to life on a map.

“The Bird Migration Explorer is an urgently-needed new tool for conservation and an outstanding collaborative achievement!” says Stu Mackenzie, Director of Strategic Assets for Birds Canada. “Using the explorer, people can discover the magnificence of migratory birds, the challenges they face, and efforts to conserve them – including steps anyone can take to help birds. Birds Canada is a proud partner, contributing expertise and big data from the Motus Wildlife Tracking System and projects using other tracking technologies.”

The Bird Migration Explorer includes:

  • Interactive, animated maps of the full annual migration for 458 species
  • More than 4.2 million point-to-point migratory bird connections across the hemisphere
  • Visualizations for 19 selected Conservation Challenges that migratory birds are exposed to throughout the year across the Americas.

The Bird Migration Explorer reflects an extraordinary partnership among science, conservation, and technology organizations and institutions and is made possible with data from the following partner organizations and more than 500 studies from researchers and institutions from around the world:
