Great news from Cockscomb Basin, and the Howler Monkey population located there. National Geographic has a detailed article about the research of the Howler Monkey reintroduction.
"Twenty-five years on, we are pleased to report that the reintroduction is a success. The howler monkeys have re-established themselves throughout the Cockscomb Basin, and are even found in villages and forested areas bordering the sanctuary. The team found 67 howler monkeys and evidence of many more.
Once again, the deep throated-roar of howler monkeys is a regular sound that echoes through the forests of the Cockscomb Basin, and howling battles can be heard bouncing back and forth over the forest canopy as male howler monkeys announce their presence to neighboring troops."
