One of the most noticeable and natural sounds that can be heard in the Orinoco rainforest at the DWA is the "howling" of the Red howler monkeys! Whether it be early in the morning, late in the evening, or perhaps a high school group of students that seemed particularly worth warning, Red howler monkeys (Alouatta seniculus) announce their presence and their territory with loud vocalizations. This is enabled by an enlarged goiter-like hyoid bone that gives resonance to their sounds.

Our first Howler troop arrived in 1998, after many years of working with individuals and agencies in Venezuela. Few institutions at that time had been able to successfully keep howlers in captivity. Some of the howlers in the troop at The Dallas World Aquarium had been confiscated by Venezuelan authorities, after having been house pets for many years and could not be returned to the wild. After a successful introduction to Howler Junction, they have produced several offspring.

We are excited to announce the departure of two of our male Red howler monkeys, Mikey and Boxer, to the Cologne Zoo in Cologne, Germany. While we are sad to see them leave, we are excited because they are joining new troops and will soon be producing families of their own. Mikey and Boxer were among our first born. Mikey, born in October 2000, is the offspring of Rifito and Raquel. Boxer, born in December 2001, is the offspring of Rifito and Angela. Our cooperative breeding agreement with the Cologne Zoo will return designated offspring from Mikey and Boxer to the DWA in order to provide new blood lines and new genetics.
