Also, they are more active at night during dry seasons, when the lack of rain exacerbates their daytime heat stress. Nighttime activities include bathing, socializing, traveling, foraging, and long-distance vocalizing. The apes tend to bathe a lot in this region as the heat index will often reach 120 degrees Fahrenheit. Sometimes, in the heat of the night there are “romantic” disputes of “jealous” suitors, as you can see here. This study gave more insight into how apes behave during thermal stress.
