Mexico's intense heat sees howler monkeys fall dead from trees

It’s so hot in Mexico that howler monkeys are dropping dead from trees. At least 83 of the midsized primates, who are known for their roaring vocal calls, were found dead in the Gulf coast state of Tabasco. Others were rescued by residents, including five that were rushed to a local veterinarian who fought to save them. (AP/Luis Sánchez)
