Her memoir, Birding on Borrowed Time, explores this achievement.
She traveled the world multiple times to find birds in their habitats.
She was described as having had an excellent memory, and a strong competitive spirit.After receiving a melanoma diagnosis at age 50, Snetsinger took-up birding avidly, becoming known as a sharp observer who kept detailed notes.
Her multiple expeditions around the world to often remote locations occasionally proved to be dangerous.
Initially driven to join the competition of seeing the most birds by the prognosis that her cancer was fatal, she died in a vehicle accident while birding in Madagascar about 18 years after the diagnosis.
