“…The coconut palms at Babirusa Park began flowering in April 2006. However, a heavy storm at the end of 2006 damaged the plants in the study area [18,19]. Such an external factor seemed to diminish the reproductive function of the coconut palms in 2007 (Fig.…”

“…To examine this topic, we set up a research area in an outdoor enclosure in Indonesia where coconut palms had been planted for Sulawesi babirusas [18,19]. The objectives of this study were to investigate; 1) which parts of the coconut palm the babirusa eats; 2) how the babirusa opens and eats coconut fruits; 3) whether or not the babirusa should be considered an agricultural pest in coconut groves and copra-producing farms.…”

The feeding behaviours of the Sulawesi babirusa (Babyrousa celebensis) were investigated in an enclosure imitating the early phase of a commercial coconut palm (Cocos nucifera) grove. Unexpected behaviours, such as the eating of coconut flowers and the picking of young coconut fruits, were observed. Additionally, we conducted experiments in which we fed several different parts of the coconut palm to the animals. We found the following: 1) coconut seedlings and leaflets were not eaten; 2) the babirusas preferred to eat staminate flowers rather than carpellate flowers; 3) the babirusas were able to crush the young coconut fruits with its teeth, but failed to open the mature coconuts; 4) the maxillary and mandibular incisors gripped the coconut, and the tip of the mandibular incisor was then used to penetrate the coconut surface to crack it open; 5) the palatable parts were the kernel and haustorium of the mature coconut.The coconut parts eaten by the babirusas in the experiment were concordant with the pieces of broken kernels and haustorium scattered over coconut groves in copra production. These pieces have no economic value for the farmer.There was insufficient evidence to support the view that babirusas moving through coconut groves constitute vermin for the coconut farmers and copra producers.

“…In the much larger babirusa ( Babyrousa celebensis , Suidae), both sexes constructed nests using plant material available in their enclosures [120]. These structures were used for sleeping and were more common in the dry season than the wet season [121]. Increased nest construction was considered a response to decreased ambient temperature and increased wind speed, so the nest was thought to impart some thermal benefit to the individuals [121], although this was not measured.…”

Nesting behaviour in mammals has been investigated in a wide variety of species but to date there has not been any scholarly review of the incidence and roles of these nests. Not all mammals build nests but, while some large species regularly build nests, nest-building behaviour is more commonly associated with small mammals weighing less than a kilogram. Quantitative data for the amounts of different materials used in a nest are rarely reported but mammal nests are typically constructed from fresh (rather than dead) plant materials. Animal-derived materials seem to be rare in nests, but anthropogenic materials are reported. Few studies have examined the roles these different materials play but more physically robust materials provide support for the structure. Many mammal nests have maternity roles, but a variety of other roles were recognized. A wide range of mammalian orders use nests for resting and environmental protection. Less common roles were as sites for torpor or hibernation, or as a refuge from predation, or the materials may have anti-parasite properties. These different roles were often not mutually exclusive. It is hoped that this review will stimulate interest in the functional properties of mammalian nests. It also suggests various themes that would be interesting areas for future research. This article is part of the theme issue ‘The evolutionary ecology of nests: a cross-taxon approach’.

“…celebensis), 13 and 14 years of age at the onset of observations, were observed in this study. Both animals had been familiar with coconut palm trees and their fruits since they were one year old (Ito et al 2019a(Ito et al , 2019b(Ito et al , 2020. They were kept in a 100 m 2 enclosure with a ground surface of hard soil and gravel.…”
