“…Different types of food vary in their water contents, which may affect the supplementary requirements of the consumer. Moro-Rios et al (2008) proposed a systematic relationship between diet and water consumption in Alouatta clamitans, for example. At Caratinga, the diet was composed primarily of plant exudates (65.7% of feeding records: Ferrari 1991b), whereas at RBAR, the dietary staple was fungi (64.8%: Hilário and Ferrari 2010b).…”

“…Water is essential to all living organisms, and while some terrestrial animals are able to satisfy most of their needs from the moisture in their food (Nagy and Gruchacz 1994), many others depend on access to sources of fresh water, especially during certain critical periods of the year (Chapman 1988;Moro-Rios et al 2008). Despite the potential importance of this resource, most studies of primate feeding ecology provide little or no information on the acquirement of drinking water (see Lambert 2007), possibly because it is so rarely observed, especially in comparison with most other types of foraging behaviour.…”

Many primates are able to satisfy most of their water requirements from the liquid content of their food, but almost all need to visit external water sources during critical periods. The present study analyses the use of water sources in two free-ranging groups of buffy-headed marmosets (Caratinga and RBAR groups) over an annual cycle. At both sites, a large proportion of the days had no visits, and the visitation rate fell by approximately half in the wet season. Differences between sites appear to reflect both contrasts in habitat structure and the composition of the diet. Despite inhabiting a more humid environment, for example, the RBAR group visited water sources on a significantly larger proportion of days than the Caratinga group. While 94.2% of the records for the RBAR group involved bromeliads, this type of source was not recorded at Caratinga, where terrestrial sources were used relatively frequently. Seasonal variation indicates that arboreal sources are preferred over terrestrial ones at both sites, and that rivers are used as a last resort, when other sources are scarce. The use of terrestrial sources involves cautious and coordinated group behaviour, which presumably reflects the perceived predation risk. Overall, the relatively frequent use of watering sites in the RBAR group might be related to its highly fungivorous diet, in comparison with the more typical gummivorous diet of the Caratinga group, although the exact implications of this difference are not clear from the available data.

“…For large herbivores living in dry environments, water can be a limiting resource that affects their distribution and abundance in periods when water requirements are not met through forage (Villarreal-Espino and Marín 2005;Nagy and Gruchacz 1994;Eliades et al 2022). In these circumstances, many animals depend on access to surface freshwater sources, especially during certain critical periods of the year (Moro-Ríos et al 2008). Water availability is one of the factors that influence the spatial distribution of wildlife to different degrees (Paredes et al 2017); in some cases, it causes changes in the behavior of animals (Pacifici et al 2015).…”

Artificial water troughs have been implemented in the Calakmul region as a measure that contributes to the maintenance of wildlife populations during the drought season. The aim of this study was to estimate the use of artificial water troughs by three species of deer (Odocoileus virginianus, M. pandora, and Mazama temama) in the Maya Forest of Campeche in southeastern México. The study was carried out in the Calakmul Biosphere Reserve (CBR, in Spanish) in southeastern México. Seventy artificial water troughs were installed, most of them within the core areas of the CBR. Between December 2018 and August 2021, eight digital traps were placed in eight artificial water troughs to monitor the presence of deer. The Photographic Visit Index (PVI) was calculated, and the visit rates of each species were compared by sampling year for each monitoring station. Deer activity patterns were evaluated using circular statistics to assess whether there were differences between visiting times. Watson-Williams tests were performed during the different sampling months. The density of records was analyzed to identify the degree of overlap in the deer activity patterns. With a sampling effort of 4,672 nights/camera, we captured 477 records of O. virginianus, 229 of M. pandora, and three of M. temama using artificial water troughs in the CBR. Due to the scarce records of M. temama in water troughs, comparative analyses were performed only with the other two deer species. According to the PVI, in the case of O. virginianus, highly significant differences were found between the three sampling years (H = 12.575, df = 2, P < 0.001); similarly, M. pandora showed highly significant differences between sampling years (H = 9.29, df = 2, P = 0.001). Regarding activity patterns, O. virginianus is mainly diurnal, with peaks of activity in the early hours of the day (8:00 h to 9:00 h). M. pandora was also mainly diurnal, showing the highest peaks of activity in the early hours of the day and before dusk. O. virginianus and M. pandora regularly visit water troughs, and the presence of deer in water troughs responds to their need to drink water for thermoregulation. The activity pattern of deer was mainly diurnal; it is safer for both species to move during the day because predators were recorded constantly in the study area. The degree of overlap recorded between O. virginianus and M. pandora suggests that both species are active at the same times of the day.

Spontaneous ingestion of water by a free-ranging maned sloth, Bradypus torquatus, in the Ibura National Forest, northeastern Brazil

Water is an important limiting factor in the ecology of many animals, and even in rainforests, arboreal mammals, such as sloths, may have limited access to water sources. Here, we describe the spontaneous ingestion of water by a free-ranging three-toed sloth (Bradypus torquatus). The event occurred in the Ibura National Forest, in northeastern Brazil, where a sub-adult B. torquatus was monitored over three days in January, 2014. On the third day, the sloth was feeding on mature leaves and, at 16:22 h, it began raining heavily. Once the rain ceased, the sloth began to ingest the rainwater trickling down a vertical branch by licking it, and continued to ingest water for approximately 26 minutes. This behaviour indicates that the water was a valuable resource for this sloth, and sheds new light on the previous assumptions that these animals are able to satisfy their water requirements through their diet alone. This observation, together with an overview of the data on the ingestion of water by arboreal mammalian folivores, indicates that the direct ingestion of water may depend on specific local conditions, in particular, the availability of water sources, as well as the specific necessities of the mammal. As the lack of previous records of this behaviour in sloths is likely due to the cryptic behaviour of these animals, this finding highlights the importance of continuous, long-term behavioural monitoring for a more complete understanding of sloth ecology.
