Howler Monkeys go crazy in their mating song duel - Columbia Riverbanks Zoo video

That's a siamang.

Yes, these are Siamangs, a large gibbon, not a howler monkey at all. Howler monkeys do some sort of a dull roar noise, not a high pitched call like these guys

You may be right...that's what the zoo said.

Either way they're so much fun to watch!

Siamangs are lesser apes not monkeys

;-)

[dancefreaque]

you're absolutely right: there are siamangs which are lesser apes and howler monkeys which are New World monkeys. Two completely different primates

Thanks this really helped. I'm doing this on a science project on endangered species and I need to know about its mating. So thanks.
