Species inhabiting vast, open wetlands tend to have more white in their plumage than do species that inhabit smaller wetlands or forested habitats, which tend to be more grey.

, occurring across most of the world continents. They are absent from Antarctica and, mysteriously, South America. East Asia has the highest crane diversity, with eight species, followed by Africa, which is home to five resident species and wintering populations of a sixth. Australia, Europe, and North America have two regularly occurring species each. Of the four crane genera, ''Balearica'' (two species) is restricted to Africa, and ''Leucogeranus'' (one species) is restricted to Asia; the other two genera, ''Grus'' (including ''Anthropoides'' and ''Bugeranus'') and ''Antigone'', are both widespread. Many species of cranes are dependent on wetlands and grasslands, and most species nest in shallow wetlands. Some species nest in wetlands, but move their chicks up onto grasslands or uplands to feed (while returning to wetlands at night), whereas others remain in wetlands for the entirety of the breeding season. Even the demoiselle crane and blue crane, which may nest and feed in grasslands (or even arid grasslands or deserts), require wetlands for roosting at night. The Sarus Crane in south Asia is unique in having a significant breeding population using agricultural fields to breed in areas alongside very high density of humans and intensive farming, largely due to the positive attitudes of farmers towards the cranes. In Australia, the Brolga occurs in the breeding areas of Sarus Cranes in Queensland state, and they achieve sympatry by using different habitats. Sarus Cranes in Queensland largely live in ''Eucalyptus''-dominated riverine, while most Brolgas use non-wooded regional ecosystems that include vast grassland habitats. The only two species that do not always roost in wetlands are the two African crowned cranes (''Balearica''), which are the only cranes to roost in trees. Some crane species are sedentary, remaining in the same area throughout the year, while others are highly migratory, traveling thousands of kilometres each year from their breeding sites. A few species like Sarus Cranes have both migratory and sedentary populations, and healthy sedentary populations have a large proportion of cranes that are not territorial, breeding pairs.


Behaviour and ecology

The cranes are diurnal birds that vary in their sociality by season and location. During the
breeding season Seasonal breeders are animal species that successfully mate only during certain times of the year. These times of year allow for the optimization of survival of young due to factors such as ambient temperature, food and water availability, and cha ...
, they are territorial and usually remain on their territory all the time. In contrast in the non-breeding season, they tend to be gregarious, forming large flocks to roost, socialize, and in some species feed. Sarus Crane breeding pairs maintain territories throughout the year in south Asia, and non-breeding birds live in flocks that can also be seen throughout the year. Large aggregations of cranes likely increase safety for individual cranes when resting and flying and also increase chances for young unmated birds to meet partners.


Calls and communication

Cranes are highly vocal and have several specialized calls. The vocabulary begins soon after hatching with low, purring calls for maintaining contact with their parents, as well as food-begging calls. Other calls used as chicks include alarm calls and "flight intention" calls, both of which are maintained into adulthood. Cranes are noticed the most due to their loud duet calls that can be used to distinguish individual pairs. Sarus crane trios produce synchronized unison calls called "triets" whose structure is identical to duets of normal pairs, but have a lower frequency.


Feeding

The cranes consume a wide range of food, both animal and plant matter. When feeding on land, they consume seeds, leaves, nuts and acorns, berries, fruit, insects, worms, snails, small reptiles, mammals, and birds. In wetlands and agriculture fields, roots, rhizomes, tubers, and other parts of emergent plants, other molluscs, small fish, eggs of birds and amphibians are also consumed, as well. The exact composition of the diet varies by location, season, and availability. Within the wide range of items consumed, some patterns are suggested but require specific investigation to confirm; the shorter-billed species usually feed in drier uplands, while the longer-billed species feed in wetlands. Cranes employ different foraging techniques for different food types and in different habitats. Tubers and rhizomes are dug for and a crane digging for them remains in place for some time digging and then expanding a hole to prise them out of the soil. In contrast both to this and the stationary wait and watch hunting methods employed by many herons, they forage for insects and animal prey by slowly moving forwards with their heads lowered and probing with their bills. Where more than one species of cranes exists in a locality, each species adopts separate niches to minimise competition. At one important lake in

s on sedge meadows, and the last two species also feed on the agricultural fields along with the common cranes. In Australia, where Sarus Cranes live alongside Brolgas, they have different diets: Sarus Cranes' diet consisted of diverse vegetation, while Brolga diet spanned a much wider range of trophic levels. Some crane species such as the Common/ Eurasian crane use a kleptoparasitic strategy to recover from temporary reductions in feeding rate, particularly when the rate is below the threshold of intake necessary for survival. Accumulated intake of during daytime shows a typical anti-sigmoid shape, with greatest increases of intake after dawn and before dusk.


Breeding

Cranes are perennially monogamous breeders, establishing long-term pair bonds that may last the lifetime of the birds. Pair bonds begin to form in the second or third years of life, but several years pass before the first successful breeding season. Initial breeding attempts often fail, and in many cases, newer pair bonds dissolve (divorce) after unsuccessful breeding attempts. Pairs that are repeatedly successful at breeding remain together for as long as they continue to do so. In a study of sandhill cranes in Florida, seven of the 22 pairs studied remained together for an 11-year period. Of the pairs that separated, 53% was due to the death of one of the pair, 18% was due to divorce, and the fate of 29% of pairs was unknown. Similar results had been found by acoustic monitoring (sonography/frequency analysis of duet and guard calls) in three breeding areas of common cranes in Germany over 10 years. Cranes are territorial and generally seasonal breeders. Seasonality varies both between and within species, depending on local conditions. Migratory species begin breeding upon reaching their summer breeding grounds, between April and June. The breeding season of tropical species is usually timed to coincide with the wet or monsoon seasons. Artificial sources of water such as irrigation canals and irregular rainfall can sometimes provide adequate moisture to maintain wetland habitat outside the normal wet season, and allows for occasional aseasonal nesting throughout the year in few tropical species. Territory sizes also vary depending on location. Tropical species can maintain very small territories, for example sarus cranes in India can breed on territories as small as one hectare where the area is of sufficient quality and disturbance by humans is minimal. Even in areas with a high density of humans, in the absence of directed persecution, species like Sarus Crane maintain territories as small as 5 ha when agricultural crops and landscape conditions are suitable. In contrast, red-crowned crane territories may require 500 hectares, and pairs may defend even larger territories than that, up to several thousand hectares. Territory defence is either acoustic with both birds performing the unison call, or more rarely, physical with attacks usually by the male. Because of this, females are much less likely to retain the territory than males in the event of the death of a partner. Rarely, breeding territorial crane pairs allow a third crane into the territory to form polygynous or polyandrous trios that improves the chances of survival of the pair's chicks. Trios of Sarus cranes were seen largely in marginal habitats and third birds were young suggesting that third cranes would benefit by gaining experience.
