Feeding Behavior
Forages by probing in mud of exposed flats or in shallow water. Females have longer bills and may feed in deeper water than males.
Eggs
Usually 4. Olive or pale brown, usually with a few brown spots. Incubation begins with laying of last egg; both male and female incubate, and eggs hatch in about 3 weeks. Young: Shortly after hatching, young are led to nearby marshy areas, where they stay until able to fly. Both parents tend young, and young find all their own food. Age at first flight probably about 30 days. One brood per year.

Nesting
First breeds at age of two years. Territorial and courtship display of male involves loud calls and aerial acrobatics, deep wingbeats alternating with glides, as he circles high above tundra. Nest site is usually on a raised hummock, surrounded by grass. Nest is a shallow depression, lined with bits of grass, moss, lichens.

Migration
Alaskan and Siberian birds winter from southeast Asia south to Australia and New Zealand. Those from Alaska are now known to make a remarkable flight over the ocean, covering more than 6,000 miles in an epic nonstop migration that may take eight days of continuous flying. Strays in the lower 48 States may come from either Asia or Europe.
