Tropical rainforest in Argentina is restricted to the north and north-east country, the wildlife rich Misiones province, a nature photographers paradise. This is the place to find Black Howler monkeys, more likely though, you will hear them first.

 

Howler monkeys are generalist eaters, but love fruit. They live in small social groups and when a family find an area of the forest where the trees are fruiting they will stay a few days.  To avoid confrontation with other Howler families they call, howl and scream unbelievably loudly to announce their presence to other groups of monkeys in the area.

The sound is rather like a very strong, undulating wind blowing through a tunnel.  From high in the trees Black Howler monkeys will start this calling just before sunrise,it wont last that long but the sound carries over the forest in the clear calm air of the morning, wakening the senses and epitomizing the very spirit of the forest.
