In only five decades, bird populations have decreased by 29% in North America. This population decline means that ⅓ of birds that existed in 1970 do not exist today, according to a study published in Science. As with the buffalo and passenger pigeon, humans are severely damaging bird populations.
The problem extends beyond North America. According to Cornell's All About Birds, 40% of the world’s bird species are in decline. Birds need immediate attention if they are to successfully recover from these decades of damage. Rachel Carson’s Silent Spring taught millions that our actions as humans impact birds, and that is still true today. Birds are impacted by things from oil rigs to your own home. They need your help if they are going to survive in this human world.

Why Are Birds Disappearing?
These are many threats to birds, including: habitat loss, cats, collisions with building glass, oil rigs, window turbines, cars, and even poison!
Their combined pressure results in an annual estimate of 3,324,184,012 bird fatalities (not counting habit loss, which would be difficult to measure), according to US Fish and Wildlife Service.
