Sifakas Avahis and Indris: Indriidae
Behavior And Reproduction
Groups of avahis and indris have two to six members, usually an adult male and female and their young offspring. Sifakas have groups of up to ten members. Females are dominant, or in charge, in both the sifakas and indris. Little is known about avahis.
Indris and sifakas mate at three to five years old. Little is known about avahis, or woolly lemurs, although they usually have one offspring each time.
Sifakis and indris are diurnal, or active during the day. Avahis are nocturnal, or active at night.
All indriids are vertical clingers, able to climb up and down trees. They can leap long distances between trees. Indris usually stay in trees, while sifakas occasionally travel on the ground.
Scent marking and facial expressions are important means of communication for all the indriids. Vocalizations, or sounds, are also important. Among other sounds, avahis make shrill whistles, sifakas bark, honk, and making sneezing noises, and indris can sound somewhat like a loud clarinet.
