On the mornings when the rooster sleeps in, the Mantled Howler Monkeys (Alouatta palliata) step up to the plate. Though they aren’t visible in this video you can clearly hear them (but trust me, this recording is a poor substitute for the live effect).
Howler Monkeys are the loudest animals in the Americas, registering in at 140 decibels. To put that in perspective; a typical conversation is about 60db, a lawnmower about 90db, and a rock concert about 120db. Keep in mind that anything above 85db can damage your hearing.
The troop napped most of the day high up in the canopy but I was able to get a few shots when some came down lower for afternoon foraging. After snapping an underside photo of the alpha male, I think I might know one reason why they howl. Ouch!
Important tip: when photographing monkeys, do not stand under other members of the troop. Monkey sh*t happens. I’ll be filing this one under: Things I Wish Someone Had Told Me!
