Indri

Fascinating facts about the Indri

• When an indri sings, its booming call can travel for miles, echoing through the forest canopy. Songs last from 45 seconds to over three minutes, and the animals climb to treetops so the sound can be heard up to 4 km away, about 2.5 miles, matching reports that humans can hear the call from as far as 1.2 miles. This acoustic reach helps groups keep tabs on each other across a patchwork of trees.
• Indri babies spend years clinging to their mothers before venturing out on their own. Sexual maturity arrives at 7-9 years, and females give birth every two to three years after a gestation of 120-150 days, usually in May or June. The newborn clings to the mother's belly for four to five months, then moves to her back, and remains dependent for at least two years.
• Indri societies are tight-knit, monogamous families that travel together each day. Groups of three to five individuals, one mated pair and their offspring, move 300-700 m daily through the canopy, with the adult female leading travel and often displacing the male to poorer feeding spots.
• The indri teeters on the brink of extinction, classified as critically endangered by the IUCN. Estimates place the total population between 1,000 and 10,000 individuals, and numbers could drop 80 % in the next three generations, about 36 years, if current trends continue. Habitat loss from slash-and-burn agriculture, fuel-wood collection, and logging, plus hunting despite cultural taboos, drive this rapid decline.
• The indri stretches its legs to almost four feet tall. Its head-body length measures 64-72 cm and it weighs between 6 and 9.5 kg, while fully mature individuals can reach nearly 120 cm with legs fully extended.
