Cranes are huge, long-legged and long-necked birds of the order Gruiformes,
and family Gruidae. The Sarus crane is the world's tallest flying bird;
there are three recognized subspecies of the sarus crane. Its Length is
more or less 37 inches, Wingspan is 80 inches. It has Long, pointed bill.
It Holds neck straight both at rest and in flight, not tucking it in like
herons do It extended Dark gray legs in flight. The plumage is habitually
brown, gray,
or
white. Cranes frequently have deafening, resonant cries.Some species
of cranes
migrate over long distances, while some do not travel at all. Cranes are
outgoing, forming great flocks where their numbers are adequate.
They are opportunistic feeders that alter their diet according to the
period and their own nutrient necessities. They eat a variety of objects
from
fittingly
sized small rodents, fish, amphibians, and insects, to grain, berries,
and plants. They also consume seeds, small mammals and reptiles, eggs
of other birds, and invertebrates, such as worms, clams, insects, and
crayfish.
Cranes
do not have webbed feet, but they can swim, though adult birds generally
steer clear of deeper water if not essential. Though a running crane looks
discomfited, but they can without doubt outrun humans. Cranes may fly
as fast as 52 m.p.h. during level, flapping flight, but have a preference
to soar, particularly during migration. When soaring in thermals cranes
will circle until they arrive at a preferred altitude, usually between
3,000 and 5,000 feet.
