Factors affecting diet, habitat selection and breeding success of the African Crowned Eagle Stephanoaetus coronatus in a fragmented landscape

This study aimed to identify variables that affect habitat selection and nesting success of the African Crowned Eagle Stephanoaetus coronatus, the largest forest raptor, in north-eastern South Africa. A preference for nesting in the Northern Mistbelt Forest vegetation type was established and 82% of all nests were located in indigenous trees. Nest abandonment was less common when distances to the nearest neighbour were greater. The diet of this species was investigated by examination of prey remains beneath nests and verified by comparison with museum specimens. In total, 156 remains were found, representing a minimum of 75 prey individuals. The diet of African Crowned Eagles constituted almost entirely mammals (99%), which were predominantly antelopes (61%) and monkeys (25%). It was also found that the proportion of primates in the diet correlates with latitude: populations in equatorial latitudes have a higher proportion of primates in their diets, whereas further south antelopes are a much more common diet component

Treating Patients Who Threaten Violence

The problem of violence in contemporary American society is both complex and compelling.1 Interpersonal violence can occur in many forms, with death due to intentional injury being the most serious, though not the most common violent crime. In 1980 the United States homicide rate reached 10.6/100,000—the highest rate recorded this century. The lifetime risk for being a victim of homicide is 1/240 for whites and 1/47 for blacks. Further, the prevalence of nonfatal assault is about 100 times greater.
