During the winter, the Long-billed Dowitcher becomes gray and occurs in small to large flocks on wet mud flats and tidal estuaries. It catches aquatic insects and marine invertebrates by rapidly probing deep into the mud with its long bill - resembling a sewing machine going up and down and with its head often totally immersed. During the summer it becomes rusty-colored and moves to the Arctic tundra where pairs nest on moist meadows. The nest is a shallow depression in the moist grass or moss.
The four-digit banding code is LBDO.
