Seasonal Changes in the Techniques Employed by Wild Chimpanzees in the Mahale Mountains, Tanzania, to Feed on Termites (Pseudacanthotermes spiniger)

Abstract: During a short period, wild chimpanzees of group K in the Mahale Mountains employ a set of several techniques, including tool use, to feed on one species of termite (Pseudacanthotermes spiniger). They appear to use each technique appropriately according to phenological changes in the prey insect’s activities. The chimpanzees also ingest small pieces of soil from the tower of P. spiniger’s mound throughout the year. Geophagy presumably makes them visually and tactually aware of the phenological changes of the t… Show more

“…Sodium content was lower in our samples than in soil ingested by other primates (Hladik, 1977a, 1977b, Mahaney, Watts et al, 1990 and soil samples from salt licks (Weeks & Kirkpatrick, 1976;Emmons & Stark, 1979). Soil samples ingested by chimpanzees in the wet season in Gabon had higher quantities of potassium (and calcium) than their diet (Hladik, 1977b;Uehara, 1982).…”

“…Chimpanzees seem to restrict their termite-fishing technique to one species (Macrotermes subhyalinus) [5,9,20], except for one observation on Pseudacanthotermes spiniger [6], These species are re stricted to the savanna area and are absent in the Ta'i forest. Tat chimpanzees were never observed to fish for any termite species, al though they feed on 5 species of termites without the help of tools (Macrotermes ivorensis are present but, with openings meters away, possess a very different structure of their underground mounds than M. subhya linus and my own efforts to fish them were never successful).…”

“…For example, chimpanzees modify and use stick tools to extract termites (Sanz et al, 2004;Wright et al, 2009;Yamagiwa and Basabose, 2009) and different tools to obtain pith and leaves (Malenky and Wrangham, 1994;Wrangham et al, 1998;Yamakoshi, 1998;Basabose, 2002). Modern chimpanzees extract invertebrates regularly (Uehara 1982;Nishida and Uehara 1983;Sanz et al, 2004;Sch€ oning et al, 2008;Bogart and Pruetz, 2010;O'Malley and Power, 2014), and may fall back on them when ripe fruits are scarce (Yamagiwa and Basabose, 2009). In this study, we focus on another lineage of large-brained, tool-using primates with high levels of sensorimotor cognition-capuchin monkeys (Parker and Gibson, 1977;Ottoni and Izar, 2008).…”
