Behavior of snow monkeys hunting fish to survive winter
Abstract
Japanese macaques, Macaca fuscata, of Kamikochi in the Japanese Alps
endure one of the coldest and harshest environments during winter when
scarcity of food puts them at risk. However, various behaviors have
evolved to mitigate potential mortality. These macaques typically eat
bamboo leaves and the bark of woody plants in winter, but our previous
study using the feces of Japanese macaques collected in the winter and
DNA metabarcoding analysis revealed conclusively for the first time
consumption of riverine benthos and brown trout. In this paper, we
investigate how Japanese macaques hunt fish and collect these riverine
biota by extensively observing their behavior, including the use of
infrared sensor cameras. Many researchers have tracked Japanese
macaques as part of behavioral and ecological studies, but previously
the techniques by which Japanese macaques capture swimming fish has
not been documented. Herein, for the first time we consider how novel
macaque foraging behavior traits have evolved to secure valuable
animal protein for winter survival when food resources are scarce.
