The count, organized by the Cornell Lab of Ornithology, the National Audubon Society and Birds Canada, is held for four days each February to take stock of global bird populations before they undertake seasonal migration starting in March. This year’s event runs from February 13 through February 16. During this time, participants are encouraged to observe birds in a location of their choosing for 15 minutes or more at least once and to identify and count all of the birds they encounter in that interval. People can report their findings—and share any photographs—via the eBird or Merlin Bird ID apps, which are available for iOS and Android smartphones.
