Often referred to as the \u201ceighth continent,\u201d the island nation of Madagascar<\/a> has developed its own distinct ecosystems and extraordinary wildlife since it split from the African continent an estimated 160 million years ago. Approximately 95% of Madagascar\u2019s reptiles, 89% of its plant life and 92% of its mammals exist nowhere else on Earth.<\/p>\n

The ZZuss<\/em> of the Silky Sifaka <\/strong><\/h2>\n

Among these endemic species is one of the rarest mammals on the planet, the critically endangered silky sifaka<\/a> lemur (Propithecus candidus)<\/em> of the Indriidae<\/a> <\/em>family. Named after the Malagasy<\/a> word shif-auk<\/em>\u2014which sounds like the lemur\u2019s echoing calls, and known by local communities as the \u201cangel of the forest,\u201d this arboreal primate is one of few animals known to \u201csing\u201d like humans.<\/p>\n

\"ENDANGERED<\/p>\n

Silky sifakas live in the humid terrain of northeastern Madagascar, where they feed on a variety of leaves, fruits and flowers. This lemur is characterized by silky, snow-white fur, which contrasts starkly with its deep yellow eyes. This species inhabits Marojejy National Park, Anjanaharibe-Sud reserve<\/a>, Makira Natural Park and the COMATSA-Sud protected area.<\/p>\n<\/div>\n

Silky sifakas live in small family groups\u2014also called a conspiracy<\/em>\u2014of two to nine individuals. Their social structure is either polygynous with a single adult male and multiple adult females (seldom more than 2), or pair-bonded with one adult female. Like other lemurs, communication is achieved through a combination of olfactory, visual and aural cues. In addition to scent-marking, body posturing and facial gestures, silky sifakas communicate through a plethora of auditory forms.<\/p>\n

While the evolution and exact function of these vocalizations require further study, scientists have observed that the songs serve to establish and maintain social bonds, assert dominance and define territorial boundaries and signify impending threats.<\/p>\n

\"Sifaka<\/p>\n

Silky sifakas practice a unique form of locomotion, remaining upright as they leap from tree to tree with their powerful hind legs, clearing distances of more than 30 feet through the dense canopy. They can also move quickly on the ground, which they do using a two-legged sideways hop.<\/p>\n<\/div>\n

Adult eastern sifakas have an estimated seven call types, and infants utter several specialized vocalizations as well. The most frequently emitted calls are low-amplitude, low-frequency, tonal \u201chums\u201d and \u201cmums,\u201d which convey relational connections, group movements and foraging intel. The loudest vocalizations are alarms, which are produced by all group members in response to terrestrial disturbances, encroaching predators and calls or howls made by other conspiracies.<\/p>\n

Their most distinct alarm call is a \u201czzuss\u201d vocalization, which sounds like a sneeze and is produced with a closed mouth. Studies have revealed that \u201czzuss\u201d vocalizations are individually distinctive and even vary between males and females.<\/p>\n

The Categorical Calls of the Indri<\/strong><\/h2>\n
\"Indri<\/p>\n

The Betsimisaraka tribal name for the indri species, \u2018babakoto\u2019, means \u2018ancestor of man\u2019 in Malagasy.<\/p>\n<\/div>\n

One of the most well-known singing lemurs is the indri<\/a> (Indri indri<\/em>), the largest of the lemur species<\/a>. Their bellowing cries are recognizable from more than a mile away and they radiate a varied vocal repertoire\u00a0that reverberates through the rain forest. Indris music may not be the most melodic to the human ear; their songs have been likened to squished bagpipes and a pod of moaning whales. However, despite their unique way of carrying a tune, indris exhibit a comprehensive understanding of complex rhythmic patterns.<\/p>\n

\"Indri<\/p>\n

Indris resemble gangly, black-and-white teddy bears with piercing green eyes. They are often spotted Andasibe-Mantadia National Park<\/a> (Perinet Reserve)<\/p>\n<\/div>\n

Indris live in a conspiracy of two to six members, comprising two adults and their offspring, with females serving as the dominant sex. As soon as the morning sun breaches the canopy, the parents perform a temporally coordinated lament; their duet is followed by a cacophonous chorus by the young. Being part of a family band not only reinforces their bond, but it wards off unwanted attention from competing conspiracies and hungry predators.<\/p>\n

\u201cCategorical rhythms in a singing primate<\/a>,\u201d published in Current Biology in 2021 best captures the significance of lemur communication. Over a 12-year period, researchers from the University of Turin in Italy sampled approximately one percent of all living indri individuals. Led by Primatologist Chiara De Gregorio, the team recorded 636 songs from 20 indri groups\u2014a combined 39 individuals. <\/span><\/p>\n
