This was the scene about six miles from the heart of Cordova this past Friday morning, and this is but a sliver of the many thousands of shorebirds that stop for a short while to fuel up and rest on tidal mudflats near the town as they make their way to nesting grounds further north. Figuring in nearby barrier islands and additional flats in the Copper River delta, some five million shorebirds represented by several species will visit the Cordova area over a few days in early May. While they are here, these Western Sandpipers will double their weight. The delta is absolutely critical to the health of these avian populations as there are only a few places in the world that offer the sheer biomass of invertebrates and biofilm these birds require in order to complete journeys that in many cases cover thousands of miles. Look for a more indepth article on this incredible migratory event in the coming days.
