On May 25, 2020, Amy Cooper—a white Canadian woman—called the police on Christan Cooper—a black birdwatcher—after he asked her to leash her dog in an on-leash part of Central Park, New York City. From this incident rose Black Birders Week, an event organized by BlackAFinSTEM with the goal of increasing the viability of Black scientists in natural sciences and of highlighting the unique challenges and dangers faced by Black folks participating in outdoor activities.
