Bird Life of Hermanus, Cape Town & the Western Cape
The Blue Crane is the smallest of the Crane species and found mainly in the Overberg and Swartland regions of the Western Cape, which is home to a population of approximately 20,000 individuals. (There is also a small population of 60 birds at the Etosha National Park in Namibia.)
The Overberg country fields with its ever changing colours, hues and undulating tapestry is a pleasure to behold. The Blue Crane’s natural habitat within this region is dry grasslands and shallow wetlands, but has adapted well to the artificial grasslands created by the grain / pasture farming systems in the Overberg Region. Adults have a varied diet – depending on availability – of grain (wheat, barley, maize), insects and lucerne. These birds do not have crops like most other birds and need to eat small stones to aid digestion.
The Blue Cranes engage in an enchanting courtship, accompanying by a series of complex coordinated calling in unison. The dancing consists of various behaviours such as bowing, jumping, running, stick or grass tossing and wing flapping. Apparently it’s also done for releasing tension and to strengthen the bond between the couple. These birds pair for life from the age 3 to 4 years old.
Normally they have 1 to 3 chicks and an incubation period, done by both sexes, is about 30 to 33 days. Chicks fledge (1st flight) between 3 to 5 months of age. An adult Blue Crane grows to 4 foot tall, (a height of 117 cm) and weighs 5.1 kg.
For protection from predators, like Jackal and Caracal, they roost in water at night. The male Crane normally takes the role of protecting the nest from possible danger.
The Blue Crane is regarded as one of South Africa’s most endangered bird species and is listed as globally threatened in the International Red Data Book. A breeding program has been recently introduced to increase the population of these rare birds within the Hermanus and Overberg Region, with much success. The Western Cape has a stable and increasing population of South Africa’s National Bird the Blue Crane, due to the concerned and protective attitudes of the farming communities in these areas, toward ongoing contributions to Blue Crane conservation.
