Although Canada is home to billions of birds, many species are showing population declines as a result of stresses to our ecosystems. Widespread loss and fragmentation of habitat has increased the number of interactions between birds and human activities. To better understand and address the resulting impacts, Environment Canada scientists undertook a series of innovative studies to estimate the number of birds and nests inadvertently destroyed annually within Canada, as a result of a range of human activities.
