Orangutan male

Orangutan males weigh over 200 pounds, twice to three times the size of females. They are usually solitary until they find a receptive female, and then they will stay with her for several days before resuming their bachelor life. They spend more time on the ground than females and juveniles, probably because of their large size. Orangutans can be very agressive toward other orangutans, being mainly solitary and fiercely territorial. Orangutans are very intelligent. They have been seen using objects as tools, and they will often use leaves as umbrellas to avoid getting wet. Males make very long, loud calls that carry through forests up to 1 km. These calls help the male claim his territory, call to females, and keep out intruding males.
