Howler Monkey sees a howler monkey

My parents and I took the kids to the zoo and we got to see and hear the Howler monkeys. I wish I had taken a video because it is pretty crazy to hear them going. I thought it was a recording. It's funny because we call Joshua a howler monkey from time to time. I took a picture of Joshua pointing at their enclosure. I have also put a link to a youtube video so you can hear a real howler monkey.
