    • Avian Demographic Data from the Colville River Delta, Alaska

    Metadata Updated: July 6, 2024

    This data release contains multiple tables with information on avian demographics collected at the Colville River Delta, Alaska, 2011-2018. Researchers with the U.S. Geological Survey began studying the reproductive ecology of birds at a site on the Colville River near the Beaufort Sea coast in 2011. Researchers monitored the nests of geese, shorebirds, and landbirds at this study site, determining basic information like arrival dates, nest initiation date, clutch size, hatching success, and rates of chick growth. This release also contains first arrival observations of birds collected by Jim and Teena Helmericks from 1960-2019 at their house located ~15 km northeast of the USGS field camp.
