Birds mark the changing seasons and their numbers indicate the health of the ecosystems they inhabit. Birds hold great cultural, ecological, and economic importance—providing valuable services to natural and agricultural systems. Birds are also in steep decline. A study published in Science in 2019 found that North American bird populations have declined by an alarming 3 billion individuals since 1970, a loss of nearly 30% of all birds. To stop the staggering loss of birds, we must identify the causes of their decline, recommend solutions in conservation practice and policy, and broaden awareness of the need for an urgent response.
