Counting birds : the idea that helped save our feathered friends
(Book)

"Kids can learn how to help protect bird species, with Counting Birds - the real-life story of bird counting and watching. Frank Chapman loved birds. He created bird exhibits at the American Museum of Natural History, and started a magazine "Bird-Lore." Back then, some sports hunters had a "Christmas Day bird hunt". People shot every bird they could see and counted them at the end of the hunt. The team with the most birds was the winner. Bird-Lore proposed a different hunt: spend part of the day counting the birds and sent a report of the "hunt" to Bird-Lore. The first year, 1900, 27 watchers counted 18,500 birds in 25 locations. The project grew! It spread around the world from back yard feeders to out in the wild, from Greenland to Antarctica! In 2016, 73,153 birders counted over 56 million birds! You can join them through the Audubon chapter near you. Happy Birding!" --,(Source of summary not specified)
