Large, graceful, long-legged and long-necked birds associated with wetlands or grassland. They are large groundbirds with big heads and they often have elaborate ornamentation on the head, neck, back or breast, and usually have a train of feathers at the 'tail' (the inner secondary and tertiary flight feathers of the wing look like a tail).
They are opportunistic feeders that change their diet according to the season and their own nutrient requirements. They eat a range of items from suitably sized small rodents, fish, amphibians, and insects to grain, berries, and plants.
They often congregate in large flocks, especially in winter, but solitairy when breeding. They construct platform nests of reeds and grasses in wetland and typically lay 2 eggs at a time. Both parents help to rear the young, which remain with them until the next breeding season.
