The Great Backyard Bird Count (GBBC) is an annual citizen science event arranged by the Cornell Ornithology Lab and the National Audubon Society. This year, the twentieth GBBC will take place from February 16 - February 19, 2018. During the GBBC, bird lovers from around the world are invited to create a free account on eBird (available online and as an Android or iOS app) and report on the birds they observe in their backyards or communities. In doing so, participants provide valuable information about global bird populations and migratory patterns. Those interested in participating this year may want to start by checking out the GBBC instructions, available in the GBBC toolkit section of the website. Here, visitors will also find a helpful bird list, along with a collection of online guides and "tricky bird IDs."
