African Crowned Crane Kenya
African Crowned Crane - National Bird of Uganda
The grey crowned crane is a bird species that measures approximately 1 meter (3 feet 3 inches) in height, weighs around 3.5 kilograms (7.7 pounds), and has a wingspan of 2 meters (6 feet 7 inches). Its body plumage is predominantly grey, while the wings display a mix of colors, with a distinctive black patch at the top. The head is adorned with a crown of stiff golden feathers, and the sides of the face are white. It also possesses a bright red inflatable throat pouch. The bill is relatively short and grey, and the legs are black. The species has long legs adapted for wading through grasses, and its feet are large and slender, primarily designed for balance rather than defense or grasping. While males tend to be slightly larger, the sexes are generally similar in appearance. Younger cranes have a more grayish coloration than adults, along with a buff-colored face covered in feathers.
One notable characteristic of the grey crowned crane is its ability to roost in trees, a trait it shares only with the black crowned crane. This capability is attributed to a long hind toe that allows them to grasp branches. This feature is considered an ancestral trait among cranes, which has been lost in other crane species. Additionally, grey crowned cranes lack a coiled trachea and have loose plumage compared to other cranes.
They are monogamous and mate for life. During the breeding season, grey crowned cranes engage in an elaborate display that includes dancing, bowing, and jumping. They also produce a booming call by inflating their red gular sac, which is different from the trumpeting sound made by other crane species. Both males and females participate in the dance, and young cranes join the adults in these displays. Dancing serves as an integral part of courtship but can also occur at any time throughout the year.
The grey crowned crane holds special significance in Uganda, where it is the national bird. It is prominently featured in the country's flag and coat of arms.
