Scores of communities recognized for their bird-friendly ways through the Bird City Wisconsin program will host bird festivals in the next few weeks, including on May 11. That’s the day recognized globally as World Migratory Bird Day. Many birding organizations will host events as well.

Migration, when 60 percent to 70 percent of bird mortality occurs, is the most perilous time of a bird’s life. Storms, loss of stopover habitat, window collisions, power lines, outdoor cats and other predators are part of the gauntlet birds survive to reach Wisconsin, said Ryan Brady, a Wisconsin Department of Natural Resources conservation biologist who monitors bird populations.

This year’s World Migratory Bird Day theme highlights the importance of insects to birds. Insects are essential sources of energy for many migratory bird species, not only during the breeding seasons but also during their extensive journeys and greatly affect the timing, duration and overall success of bird migrations, according to the WMBD website.

Along their migration routes, birds actively seek out insects in fields, forests, wetlands and various habitats during stopovers. The timing of bird migration often coincides with peak insect abundance at stopover locations, supplying nourishment for birds to replenish their energy reserves before continuing their journeys. You can support insects for birds by using native plants and avoiding pesticides or other lawn chemicals, according the WMBD website.
