Most of us don’t have to look very hard to find a bird: Whether they’re singing in our yard, fluttering around at the park or soaring above skyscrapers, birds are a fun and beautiful part of the backdrop of our lives.
However, even though our feathered friends are part of our environment, many of our human-made advancements, such a lights, glass and tall buildings, continue to interfere with bird populations all across the world. And, as spring migration creeps closer, local and migrating birds will have to face many obstacles as they make their way home. In fact, it’s truly remarkable that birds have managed to survive amongst all of these threats!
Despite their ability to seemingly adapt to some shifts in their environment, birds still need your help to improve their chances of survival. So, we want to share some ways that you can help to build, and maintain, bird-friendly environments wherever you go.
Although birds seem perfectly content to build their nests under patio awnings and feast on birdseed, one study found that “urban landscape[s] and soundscape[s] shape the survival and health of birds in and near cities.” Authors Phillips et al. suggest that, while many bird species appear to thrive in busy cities, birds that live in areas with higher noise levels are typically not as healthy as birds in more rural locations.
The relationship between declining bird health and prolonged exposure to man-made stressors, such as light, buildings and sound, “may lead to long-term evolutionary consequences for populations adapting to city life.” Such consequences may include an increase in the number of birds hitting windows, food scarcity and lower breeding rates. Seasonal changes caused by global warming may also put birds at risk of a “mismatch” which, according to Nature Canada, “occurs when birds cannot shift their behaviour, such as breeding times, enough to coincide with changes in environment, such as when prey is available.” This means that birds that arrive to their nesting grounds too early may fail to find adequate food or shelter, which poses new and unexpected challenges.
A 2018 article published by the Conversation reported that birds that lived in crowded and noisy cities tend to display more aggressive behaviour than their rural counterparts, which reflects their desire to protect their shrinking territories. In addition to high noise levels, birds living in, or passing through, urban environments will face other stressors, such as artificial lights, domestic predators, diseases, pesticides and glass windows on a daily basis. Nature Canada also reported that global warming has drastically altered seasonal bird behaviours, since shifts in insect population and temperature have caused birds to not only fly home earlier than usual, but also delay their winter migration.
Approximately 1 billion birds in North America will die from window collisions each year. And, unfortunately, bustling city centers, artificial lights and glass buildings will continue to develop along the main Flyways, increasing the risk of collision and death for migratory birds. Andrés Jiménez Monge, a program coordinator for Birds Canada, points out that, because birds rely on these migratory routes, citizens and government bodies must strive to be “stewards of these flyways” to improve bird safety.
So, what exactly can residents do to support birds on their journey home? Here are a few simple ways that you can get started:
