Bibliography: leaves 87-93. / The Wattled Crane Grus carunculatus is a globally endangered resident of sub-Saharan Africa (Figure 1.1, Collar and Stuart 1985). The total population of Wattled Cranes is poorly known and estimates vary widely (Table 1.1). In 1985, Urban (1988) estimated the population at about 13 000 - 15 000 birds, while the IUCN (The World Conservation Union) Red Data Book suggested a total population of only 7 000 (Collar and Stuart 1985). Urban (1996) again estimated the total population at about 13 000 - 15 000 birds, but with a markedly different distribution among range countries. Most recently, regional surveys coordinated by the International Crane Foundation and South African Crane Working Group indicate a total population of aonly about 8 000 birds (R.Beilfuss in litt.).
