Howler monkeys are dropping dead from the trees in Mexico in brutal heat wave

It’s so hot in Mexico that howler monkeys are falling dead from the trees. At least 138 of the midsize primates, who are known for their roaring vocal calls, have been found dead in the Gulf Coast state of Tabasco. Others were rescued by residents, including five that were rushed to a local veterinarian who battled to save them. Mexico has been hit by a harsh drought and extremely high temperatures. A third of the country saw highs of 113 degrees Fahrenheit on Tuesday. Lakes and dams are drying up and water supplies are running out. Authorities have had to truck in water for everything from hospitals to fire-fighting teams.
