Geographic coverage

The Macaulay Library regularly undertakes recording expeditions to increase the breadth and depth of vocalizations and behaviors in the archive. In recent years we have targeted regions with a high diversity of species that are not yet well covered. See our Big Year Expeditions website ( detailing our efforts in 2007 to record North American birds in Alaska, Florida, Nova Scotia, and Texas. Between 2008-2010, expeditions visited the Canadian Arctic, Guatemala, South Carolina, Texas, western Mexico, the Great Basin and the Louisiana Gulf coast.
