The Pacaya-Samiria reserve is one of the least accessible places in Peru. And it is home to a great variety of animals. Some of them are listed below.
The pictures were taken during one of the expeditions to the reserve.
To hear the sound of these animals in the rainforest is an amazing experience. Their voice might sound like a banshee form the distance, however if you get the chance to stand right beneath the screaming male it is a rumble! There is a high probability of meeting this animal in the reservation. If you are lucky enough you can watch the family (that is one male and three to four females) by the side of the river in the treetops.
This kind of tamarin lives only in the western part of Amazonia. It lives on fruit in the rainy season and in the dry season it feed itself with flower nectar and tree sap. Tamarin eats insect throughout the year as well.
Three-striped Night Monkey
This is the only nocturnal kind of monkey in Amazonia and it spends the day inside of the trees. It is a very curious animal and even the slightest sounds attracts its attention. You would have hard times looking for this animal without the help of the tourguide.
This is one of the most numerous kind of parrots in Amazonia. It is usually flying around in pairs however if you are lucky you can spot quite a big flock of these birds in the trees along the river.
Hoatzin is a bird that lives near the rivers in Amazonia. It usually stays in the bushes or tree branches along the river. It feeds on leaves most of the time. It is possible to get quite close to this animal as it does not like flying. It moves around in big flocks and often times you can see it basking or bathing in the rain.
This big black bird has a long spiny structure projecting forward from the crown which it probably uses when fighting over a female or defending its territory. It usually moves around in pairs or small groups. Often times you can spot it in the treetops along the rivers. It has a very strong voice which you can hear kilometres away.
Amazon River Dolphin
There are two kinds of freshwater dolphins living in the Peruvian Amazion. It is the Amazon river dolphin and Tucuxi and i tis very easy to find them in Rio Samiria. The Amazon river dolphin has a bit of a pink appereance and its dorsal fin is not as big as in the case of Tucuxi.
The Spectacled Caiman and the Black Caiman
Caiman crocodilus & Melanosuchus niger
It is the best to watch both of the kinds of caiman in the night as their eyes shine in the dark when you point at them with the flashlight. The black caiman is much more rare than the spectacled one. But one advice: Do not try to catch them!
… and many frog species
Marbled Tree Frog
It has been found on leaves and branches of primary and secondary tropical rainforest and in clearings near forest. It is a nocturnal species, usually in trees, but after heavy rains males call from the ground, grasses, herbaceous vegetation, or bushes around temporary ponds.
Red-snouted Tree Frog
This large, arboreal, nocturnal frog inhabits a vast array of habitats, from open environments to moist forests. This species generally breeds in small temporary pools. In cultivated areas, the species breeds in roadside ditches and shallow, temporary ponds.
Polka-dot Tree Frog
In the Iquitos region, Perú, this frog is common in permanent and semi permanent open ponds, where males call from water surface amidst grassy areas. Eggs and tadpoles develop in the water. It can occur in badly degraded habitats, rural gardens and sometimes in towns.
Map Tree Frog
This nocturnal treefrog is found in trees and on branches along streams, open ponds, lakes and in gaps in primary forest. Reproduction takes place in permanent waterbodies.
A nocturnal and terrestrial toad that inhabits humid areas with adequate cover, including cane fields, savannah, open forest, well watered yards and gardens. It also inhabits dry equatorial forests. It thrives in degraded habitats and man-made environments, and is occasionally found in pristine lowland and montane rainforests, but generally prefers open or disturbed habitat such as tracks, roads, low grassland and areas that are near human settlement, e.g. grazing land, suburban parks and gardens. It tends to avoid more densely vegetated areas (eg. wet sclerophyll and rainforest), which can then act as a barrier to their dispersal. It can be found by day beneath fallen trees, loose boards, matted coconut leaves, and similar cover.
Lime Tree Frog
This species is found in flooded plains, floating meadows, ponds and large lagoons with floating vegetation (especially Eichhornia sp.) in forest clearings, at forest edges and in savannah, where males call from herbaceous vegetation just above the surface of the water. It has also been found under the leaf litter in tropical rainforest, and in seasonally flooded agricultural land. At night, this semi aquatic frog congregates at permanent or semi-permanent ponds in open areas. The males call from floating vegetation or emergent grasses.
