CITES Appendix II. CMS Appendix II. Conservation measures have expanded in scale since the mid-1980s, including efforts to mitigate power-line collisions, addressing illegal trade, the adoption of stricter legal protection, local and national surveys in South Africa, increasing research on the species's biology and ecology, habitat protection and management programmes (especially on private land), establishment of local conservation organisations, and the development of educational facilities, programmes and publications (Archibald and Meine 1996, Barnes 2000). The introduction of more ecologically sensitive agrochemicals and tighter controls over their use has reduced the number of poisoning events (K. Morrison et al. in litt. 2007). The formation of a Crane Working Group in Namibia has facilitated education, surveys, ringing and protection (R. Simmons in litt. 2007). Future studies in Namibia will assess whether its population is genetically isolated from that in South Africa, and will use transmitters to help study habitat use, their choice of breeding areas and the occurrence of inter-breeding (Simmons et al. 2006). Conservation Actions Proposed
Prevent conversion of grassland habitat to other land uses and secure sites critical to cranes in the grasslands (K. Morrison et al. in litt. 2007). Monitor the species's population trends through regular surveys. Include habitat management in future planning of afforestable regions (Barnes 2000). Encourage more responsible use of agrochemicals (Barnes 2000). Target awareness campaigns at the farming community so as to increase awareness and reduce deliberate poisoning of cranes for food (Barnes 2000, K. Morrison et al. in litt. 2007). Further research the impacts and risk factors involved in power-line collisions, and use the results of this research to make hazardous power-lines more visible with appropriate devices (Barnes 2000, Shaw et al. 2010). Discourage the taking of fledglings from the wild (Barnes 2000). Encourage the retention of a mosaic of pasture and cereal cultivation in the Western Cape (Bidwell et al. 2006). Increase conservation protection of grasslands and wetlands north of Etosha National Park (K. Morrison et al. in litt. 2007) and establish captive breeding populations to support future reintroduction and supplementation efforts. A Biodiversity Management Plan for Species for cranes, as outlined in the National Biodiversity Act (2004) would encourage national support for crane conservation efforts.
The Blue Crane (Anthropoides paradiseus), also known as the Stanley Crane and the Paradise Crane, is the national bird of South Africa.
The Blue Crane is a tall, ground-dwelling bird, but is fairly small by the standards of the crane family. It is 100–120 cm (3 ft 3 in–3 ft 11 in) tall, with a wingspan of 180–200 cm (5 ft 11 in–6 ft 7 in) and weighs 3.6–6.2 kg (7.9–13.7 lb). Among standard measurements, the wing chord measures 51.4–59 cm (20.2–23.2 in), the exposed culmen measures 8–10 cm (3.1–3.9 in) and the tarsus measures 20.5–25.2 cm (8.1–9.9 in). This crane is pale blue-gray in colour becoming darker on the upper head, neck and nape. From the crown to the lores, the plumage is distinctly lighter, sometimes whitish. The bill is ochre to greyish, with a pink tinge. The long wingtip feathers which trail to the ground. The primaries are black to slate grey, with dark coverts and blackish on the secondaries. Unlike most cranes, it has a relatively large head and a proportionately thin neck. Juveniles are similar but slightly lighter, with tawny coloration on the head, and no long wing plumes.
Blue Cranes are birds of the dry grassy uplands, usually the pastured grasses of hills, valleys, and plains with a few scattered trees. They prefer areas in the nesting season that have access to both upland and wetland areas, though they feed almost entirely in dry areas. They are altitudinal migrants, generally nesting in the lower grasslands of an elevation of around 1,300 to 2,000 m and moving down to lower altitudes for winter. Though historically found in areas of low human disturbance, the blue crane is currently thriving in the highly transformed agricultural areas of the Western Cape. This is the only portion of its range where the population is increasing, though they still face threats such as poisoning in the region.
Movements and behaviour
Of the 15 species of crane, the Blue Crane has the most restricted distribution of all. Even species with lower population numbers now (such as Siberian or Whooping Cranes) are found over a considerable range in their migratory movements. The Blue Crane is migratory, primarily altitudinal, but details are little known.
The Blue Crane is partially social, less so during the breeding season. There is a strict hierarchy in groups, with the larger adult males being dominant. They overlap in range with 3 other crane species but interactions with these species and other "large wader" type birds are not known. They are relentlessly aggressive to various other animals during the nesting season, attacking non-predatory species such as cattle, tortoises, plovers and even sparrows. Humans are also attacked if they approach a nest too closely, with the aggressive male having torn clothes and drawn blood in such cases.
Blue Cranes feed from the ground and appear to rarely feed near wetland areas. Most of their diet is comprised by grasses and sedges, with many types fed on based on their proximity to the nests. They are also regularly insectivorous, feeding on numerous, sizeable insects such as grasshoppers. Small animals such as crabs, snails,frogs,small lizards and snakes may supplement the diet, with such protein-rich food often being broken down and fed to the young.
The breeding period is highly seasonal, with eggs being recorded between October and March. Pair-formation amongst groups often beings in October, beginning with both potential parents running in circles with each other. The male then engages in a "dance" flings various objects in the air and then jumps. Eventually, a female from the group and the male appear to "select" each other and both engage in the dance of throwing objects and jumping. After the dance, mating commences in around two weeks.
In a great majority of known nests, two eggs are laid (rarely 1 or 3). Both males are females will incubate, with the male often incubating at night and, during the day, defending the nest territory during the day while the female incubates. The incubation stage lasts around 30 days. The young are able to walk after two days and can swim well shortly thereafter. They are fed primarily by their mothers, who regurgitates food into the mouths. Depending on the growth rate of chicks, the fledging stage has been reported when the young are anywhere from 30 to 60 days old. The young continue to be tended to until the next breeding season, at which time they are chased off by their parents.
While it remains common in parts of its historic range, and approx. 26 000 individuals remain, it began a sudden population decline from around 1980 and is now classified as vulnerable.
In the last two decades, the Blue Crane has largely disappeared from the Eastern Cape, Lesotho, and Swaziland. The population in the northern Free State, Limpopo, Gauteng, Mpumalanga and North West Province has declined by up to 90%. The majority of the remaining population is in eastern and southern South Africa, with a small and separate population in the Etosha Pan of northern Namibia. Occasionally, isolated breeding pairs are found in five neighbouring countries.
The primary causes of the sudden decline of the Blue Crane are human population growth, the conversion of grasslands into commercial tree plantations, and poisoning: deliberate (to protect crops) or accidental (baits intended for other species, and as a side-effect of crop dusting).
The South African government has stepped up legal protection for the Blue Crane. Other conservation measures are focusing on research, habitat management, education, and recruiting the help of private landowners.
The Blue Crane is a bird very special to the amaXhosa, who call it indwe. When a man distinguished himself by deeds of valour, or any form of meritorious conduct, he was often decorated by a chief by being presented with the feathers of this bird. After a battle, the chief would organise a ceremony called ukundzabela – a ceremony for the heroes, at which feathers would be presented. Men so honoured – they wore the feathers sticking out of their hair – were known as men of ugaba (trouble) – the implication being that if trouble arose, these men would reinstate peace and order.
The Blue Crane is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
