the.com/shorebird

A bird that commutes to the edge of the ocean to argue with the tide.

means A general term for the many wading and running birds—like sandpipers, plovers, and curlews—that feed and nest along coastlines, mudflats, and marshes rather than swimming or wading in deep water.

from A plain compound of 'shore' (land bordering water, from Old English/Germanic roots meaning a cut or division, the line where land is sheared from sea) and 'bird.' No myth or hidden root here — it's a descriptive, workmanlike English coinage, the kind naturalists and birders favored once they needed a tidy category for the sandpipers, plovers, and stilts that make their living at the water's edge rather than on it or far from it.

bill diversity
Each species' beak length matches its preferred mud depth.
migration feat
Some fly nonstop for days between hemispheres without landing.
not all wade
A few shorebirds, like killdeer, live far from any shore.
feeding tactic
They time meals to low tide, when mudflats expose buried prey.
