Every spring, the mudflats at the mouth of the Chehalis River become one of the loudest places on the Washington coast. Not from waves or wind, but from birds -- hundreds of thousands of them, packed so densely that the ground itself seems to ripple and shift. Grays Harbor National Wildlife Refuge occupies a modest footprint within the estuary, but the numbers it produces are staggering: up to one million shorebirds funnel through in spring and fall, making this one of only four major staging areas on the entire Pacific Flyway. The refuge holds just two percent of Grays Harbor's intertidal habitat, yet it hosts up to half of all the shorebirds that stop here.

The landscape of the refuge is deceptively simple. Intertidal mudflats give way to salt marsh, which grades into upland meadows and shrub thickets. But that simplicity masks a system of extraordinary biological productivity. Twice a day, the tides rework the mudflats, exposing fr...
