Five Incredible Ways Birds Change Their Bodies for Spring and Fall Migration
To power perilous journeys, birds undergo extreme feats like doubling their body weight and rearranging or even consuming their internal organs.
Limosa lapponica
| Conservation status | Most of population is in Old World. Alaskan breeding numbers seem to be stable. |
|---|---|
| Family | Sandpipers |
| Habitat | Mudflats, shores, tundra. In Alaska, nests on rolling hills of tundra, on slopes with hummocky ground cover and low stunted shrubs, a habitat shared with Whimbrels; adults may feed on coastal lagoons some distance from nesting sites. In migration and winter mainly on tidal mudflats along coast. |
Forages by probing in mud of exposed flats or in shallow water. Females have longer bills and may feed in deeper water than males.
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.

Includes insects, crustaceans, mollusks. In summer in Alaska, feeds mainly on aquatic insects, also occasionally seeds and berries. On mudflats and shores at other seasons, feeds on crustaceans, mollusks, insects, annelid worms.
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.

Some of the most impressive bird migrations shrink the distance across our largest ocean.
Predators now wipe out 70 percent of shorebird nests in the far north, a shift in historical patterns that scientists pin on climate change.
