howler

As the researchers note, arboreal howlers are extremely slow-moving primates who are very careful about the way they exert their energy.

Mexico has also been baking under a heat wave so intense that howler monkeys have literally been dropping dead from the trees.

Moreover, with heat, fires, and deforestation hitting the trees where the howler monkeys live, it was unclear whether even releasing them could ensure their survival.

Mexico’s heatwave is so dire, howler monkeys are falling dead out of trees.

For people in the steamy, swampy, jungle-covered state of Tabasco, the howler monkey is a cherished, emblematic species; local people say the monkeys tell them the time of day, by howling at dawn and dusk.
