Fun Facts

Crowned cranes are usually found in pairs, but have been seen singularly and in small flocks (3 to 20 individuals). There have been only a few observations of groups of 51 to 150 individuals.

A successful pair of mated crowned cranes will maintain their family structure for as long as 9 to 10 months. After which, the young birds tend to join together in flocks, spending much of their time feeding in fields.

Crowned cranes are the only cranes that roost in trees. All of their chicks hatch at the same time as well, which is uncommon among cranes.

Courtship is still poorly understood, however, scientists believe it is all in the mating dance between the male and female. The dance consists of bobbing, flapping wings, and swinging circles around each other.

The male is the principle defender of the pair, calling a loud warning to other cranes in his territory.

Ecology and Conservation

The numbers and range of East African crowned cranes have been reduced significantly. The principle threat these cranes face is the loss, transformation, and degradation of its habitat. Inefficient law enforcement and lack of long-term population monitoring leave the species in jeopardy.

Stronger national wetland protection policies and large-scale land development assessment would help the cranes case. Most of all, mass education about the cranes plight would provide the greatest benefit.
