It was formerly considered to be a subspecies of diademed sifaka[4] It has a very small range in northeastern Madagascar where its habitat is dry deciduous or semihumid forest.
It moves in small family groups through the canopy feeding on fruit, leaves, flowers, buds, and seeds.
The main threats faced by this sifaka are habitat destruction and fragmentation due to slash-and-burn agriculture, charcoal gathering, and logging.
The hypothesis that northern sifaka species had their distribution contract is supported by phylogeographic, genetic, and fossil data.
verreauxi (i.e. western sifaka) and P. cf diadema (i.e. eastern sifaka) were found in Ankarana (Figure 1 in Salmona et al., 2017,[9] Jungers et al. 1995) and bones of P. cf diadema were reported at Andavakoera (Montagne des Français, Figure 1 in Salmona et al., 2017;[9] Godfrey et al. 1996).
Their analyses show that P. perrieri underwent a major demographic decline, which most likely occurred after the mid-Holocene transition (in the last 5,000 years).
[10] Perrier's sifakas use vocalizations to communicate including warning calls and have even been observed to make a sound described as sneezing.
Infants have a slow growth rate given the large abundance of food on Madagascar, but dental development is just the opposite.
[13][14] While selective logging still seems to be one of the main threads in Analamerana special reserve, deforestation for slash and burn agriculture and for charcoal production is predominant in Andrafiamena-Andavakoera protected area.
