Cornell Lab of Ornithology’s bird identification app Merlin

Drawing on more than 900 million eBird project sightings, the Cornell Lab of Ornithology’s bird identification app offers a quick three-step process or photo-upload feature to make an ID and easily start creating a community science checklist. Best feature: “It allows you to set location, time, and date,” says retired physicist Steve Knox of Los Alamos. “It will show you the most likely birds to be seen along with photos and other information.”
