Rio Aripuanã – world first mammals tour

WildWings is proud to continue our long held practice of offering genuinely pioneering holidays to some incredible and exciting new destinations and our latest offering is a world’s first mammal focused wildlife cruise along the Rio Aripuanã in remote Brazilian Amazon.

Our goal is to explore the remote confluence with the Rio Roosevelt which is one of the least explored and most biologically remarkable parts of the Amazon basin, as the rivers here have acted as natural barriers driving the evolution of numerous endemic species which are found nowhere else.

Potential primate highlights include Milton’s Titi which was only described in 2014 and the little known Marca’s Marmoset and Aripuanã Marmoset. Other exciting possibilities include Prince Bernhard’s Titi, Black crowned Dwarf Marmoset, Eastern Pygmy Marmoset and Black headed Night Monkey. A good number of other monkeys species have ranges which overlap this remote area making this a truly exceptional destination for primate enthusiasts.

Birds are also a focus, with recently described species such as Aripuanã Antwren and the poorly known Manicore Warbling-Antbird among the targets.

Nocturnal canoe excursions will offer chances to look for a very different range of wildlife with one of the species we hope to see being the rarely recorded and comparatively recently described Roosmalen’s Porcupine.

Iracema is a comfortable, air conditioned vessel well suited to narrow channels so perfect for this tour. She will host just twelve participants, making this a strictly limited, once in a lifetime opportunity to explore truly frontier breaking Amazonian wilderness.

At the time of writing and only a short while after we announced this holiday only four berths remain so do contact us as soon as possible if you are interested in this special expedition.
