Avallions

Avallions are a small, nocturnal, arboreal mammal described as herbivorous in their typical natural history. Individuals are usually about 25 to 35 centimeters in length, with a prehensile tail that assists in navigating dense understory. Their fur ranges from gray to cinnamon, and they often show a pale facial stripe that helps identify individuals. Avallions possess strong incisors for processing plant material and have a quiet, agile demeanor suited to life among branches.

Geographic distribution and habitat

Avallions are native to temperate forest regions, where they inhabit mixed deciduous-coniferous woodlands. They favor dense understory and access to hollow trees or thick shrubbery for shelter. They are most commonly found at mid elevations, roughly 200 to 1,500 meters above sea level, and tend to avoid open or highly arid areas.

Behavior and ecology

These mammals are predominantly nocturnal and solitary, though they may share nesting sites in small, overlapping ranges. They communicate through a combination of scent marking, quiet vocalizations, and body postures. Foraging occurs mainly at night, with a diet consisting of leaves, shoots, fruits, and occasional bark; insects may supplement the diet in some habitats. Avallions contribute to forest dynamics through selective feeding and seed dispersal.

Reproduction and life cycle

Breeding typically occurs in the spring. Litter size is usually one to two offspring, with a gestation period around 38 to 42 days. Young are altricial at birth and remain with the mother for several weeks before independent life, reaching maturity within several months and potentially living up to a decade in the wild.

Conservation and taxonomy

Avallions are described as a single, cohesive genus within their own family in many natural history accounts. Conservation concerns arise from habitat loss and fragmentation, as well as predation by native and introduced species. In regions where forests remain intact, avallion populations are generally more stable.
