Ecosystem and habitat
These whimbrel species have low forest dependence. They normally occur in altitudes from 0 to 100 meters. The artificial ecosystems and habitats of these species include, flooded agricultural lands, ploughed lands and flooded pasturelands.The natural ecosystems and habitats of these whimbrel species include, boreal forests, mangrove forests, tundra grasslands, shrub tundra, boreal shrublands, tundra wetlands, estuaries, intertidal flats, salt marshes, mudflats, marine lagoons, freshwater lakes and river systems.
Diet and feeding behavior
The diet of this whimbrel consists mainly of insects. Insects, insect larvae, grasshoppers, locusts, cicadas, crickets, beetles, spiders, earthworms, polychaete worms, crustaceans, small fish, small reptiles and plant material are their primary food.The whimbrels feed by probing soft mud with their long sensitive bill for small invertebrates. They also feed on the prey picked up from dry grounds.
Reproduction and breeding habits
The breeding season of these whimbrel species is during May and June in northern Europe. The laying season is during May in in rest of the breeding range. These birds are monogamous and territorial.The whimbrel nesting sites are usually located in humid moss, lichen and hummock tundra, dry scrub heathland and shrub tundra. The nest is a scrape on the bare, dry, exposed ground.
The typical clutch of whimbrel contains three to five buff colored eggs with heavy brown blotching. Both parents take part in incubating eggs and caring for the chicks.
Migration and movement patterns
These whimbrel species are migrant birds. The migratory breeding populations are distributed in northern Europe, northern Asia and northern North America.The whimbrels start migrating to their wintering grounds from July onwards. They migrate over land on a broad front with few stopovers. The return migration to the breeding grounds occurs mostly from March to May. The non-breeders may remain back on the wintering grounds.
