Narrow-striped vontsira
The narrow-striped mongoose or narrow-striped vontsira (Mungotictis decemlineata ) is a member of the family Eupleridae endemic to Madagascar. It inhabits the Madagascar dry deciduous forests in western and southwestern Madagascar, where it lives from sea level to about 125 m (410 ft) between the Tsiribihina and Mangoky rivers. In Malagasy it is called bokiboky (pronounced "Boo-ky Boo-ky").

N
starts withThe narrow-striped mongoose is diurnal and lives in matriarchal family groups that practice cooperative rearing of young. Usually, the young of the alpha female will get the most care, and often the lower ranking females' young is neglected to the point of abandonment.
The narrow-striped mongoose demonstrates two unique social behaviours. Females form home ranges in their habitat, where 1-3 females form a stable social unit with their offspring. Males also form their own social units with 2-4 adult males. The male units have a large home range, which often overlap with at least 3 female social units, where mates find one another.
The narrow-striped mongoose creates small nests in trees and brush, and has been known to share trees with Lepilemur species, with which it apparently has little or no interaction. Results of a few studies suggest that the narrow-striped mongoose is primarily insectivorous, but eats also bird eggs and a variety of small animals including rodents, birds, snakes, and even small lemur species such as the gray mouse lemur.
The narrow-striped mongoose forages in top soil, ground litter and rotten wood from fallen trees. A study in the Kirindy Forest revealed that its diet consists foremost of invertebrates. It feeds on arthropods, insect larvae, gastropods. Remains of reptile eggs, bones and feathers were also found in scat collected.
Air-dried scat was used to determine preferences in the diet of the narrow-striped mongoose. Evidence showed that its diet included reptile egg membrane, bones, feathers and fragments of arthropods.Invertebrates were its main source of food during the dry season of May to August and the wet season of January to March in the Kirindy Forest.The Jaccard index was used to determine which prey items and arthropods it preferred to eat during each season of the year. The results indicated that it consumes any food that was available; it was not selective towards any particular prey item.Insect larva was a main part of its diet. It forages in top soil, ground litter, and rotten wood from fallen trees, which shows how insect larvae could be considered a staple part of its diet. Gastropoda were also found as a main source of food during rainy seasons.
Males often mate with more than one female and are considered polygamous. Females may also mate with more than one male. Narrow-striped mongooses of neighbouring units are closely related, with females more closely related than males, most likely because female disperse in a smaller area. Females give birth to one offspring per season, which is usually born at the end of the dry season between October and December.
If the cub dies, they give birth to another one by February or March. Many offspring do not survive. There is about a 28% success rate of young surviving, and it is often the oldest offspring of the most dominant female that will prevail. The gestation period lasts 74–106 days.
The narrow-striped mongoose is currently classified as endangered on the IUCN Red List because it occurs in a severely fragmented area and is threatened by habitat loss due to logging and conversion to agriculturally used land. The western dry forests are both highly fragmented and under higher human pressure than the eastern rain forests. The main cause of decimation of dry deciduous forest in Madagascar is slash-and-burn agriculture by subsistence farmers, but other causes include logging for wild honey and lumber.
