Résumé
Migratory songbirds are disappearing at an alarming rate; by some estimates we have already lost half the songbirds that filled the skies 40 years ago. Stutchbury demonstrates why this decline should concern us all by arguing that songbirds truly are… the canaries in the coal mine. Examines the most threatening factors to this vital element in our ecosystem: pesticides, the destruction of vital habitat, coffee plantations, bright lights and structures of our cities, the notorious cowbird, and global warming. 2007.
