Ranges found in eastern and southeastern African forests and wooded areas. Many duikers are found to the west of Nigeria in rainforests and other wooded areas.
Duikers tend to stay in large areas and avoid dense undergrowth. They are very choosy feeders -- diet will vary depending on season and environment. Duikers feed primarily on small fruits in rainforest, flowers, insects and fungi.
Duikers are diurnal animals. They generally spend 7 hours each day searching for food and typically range about 1/2 mi (1 km) each day. Duikers return to the same area each night to sleep, which is considered quite rare.
Most territories are around 6 to 10 acres, which is considered small by most standards. Duikers appear to be monogamous animals where the male and female share responsibilities.
Most pairs produce one calf per year if they are part of an unhunted forest population. However, in heavily hunted areas, females can produce 2 to 3 young per year. Gestation is typically 4 months.
Due to their size and tendency to range in large open areas, blue duikers are very vulnerable to predators. Crowned hawk eagle, golden cat, leopard, and baboon are the most common predators.
