Habitat
Decken's sifakas primarily inhabit dry deciduous forests in western Madagascar, favoring areas with tall trees and open canopies for movement. They are adapted to seasonal climates with wet and dry periods, avoiding dense rainforests and human-altered landscapes.
Diet
Decken's sifakas mainly consume leaves, fruits, and flowers from trees such as tamarind and fig species. They are folivorous, spending much of their day selectively feeding in the canopy to avoid toxins in certain plants, and they forage primarily during daylight hours.
Behavior
Decken's sifakas live in small family groups of 3-10 individuals, typically led by a dominant female, and they maintain territories marked by scent glands. They are diurnal and highly arboreal, spending their time leaping up to 10 meters between trees and communicating with loud, whooping calls that can travel over a kilometer. These lemurs exhibit grooming behaviors to strengthen social bonds and avoid ground travel to minimize predation risk.
Conservation Status
Decken's sifaka is classified as Endangered by the IUCN due to habitat destruction from deforestation and agriculture, with populations continuing to decline rapidly.
