Canada is home to approximately 451 bird species and billions of individual birds. Despite their numbers, the threats leading to declines in North American bird populations continue to grow. These include loss of habitat, invasive species, pesticides, toxic chemicals, pollution, cat predation, decrease in insect prey numbers, climate change, disease and death resulting from man-made obstacles like wind turbines and impact with windows of buildings during migration. As a result, nearly 15 per cent of native bird species are at risk of extinction. There is something you can do to help improve life for birds in your area.For starters, incorporate trees and shrubs from CWF's new WILD About Birds collection into your garden and landscaping projects.
