Cranes are commonly employed in transportation for the loading and unloading of freight, in construction for the movement of materials, and in manufacturing for the assembling of heavy equipment.

Cranes typically place their nests on the ground, while most herons build nests up in trees or tall marsh vegetation. Herons often nest in dense colonies but then spread out to feed as solitary individuals, while cranes often spread out to nest in isolated pairs but come together in flocks for foraging.

It is depicted in art, literature, and mythology as a symbol of good luck and longevity because it is said to live 1,000 years. An ancient Japanese legend promises that when you fold a thousand origami cranes, you will be granted a wish by the sacred crane.

Cranes are tall birds with long legs, necks and usually long bills. They resemble herons and egrets in body shape, but tend to have heavier bodies. Cranes are generally brown, gray, or white in color, although African crowned cranes (Balearica pavonina) feature a striking gold crown of feathers on their heads.
