FAUNA IN BARILOCHE


Bariloche Nature ...

Hidden in the thick of the woods, fauna is omni-present in San Carlos de Bariloche, offering the evidence of footprints and tracks to the attentive tourist.

One of the emblematic birds of Argentine Patagonia is the majestic condor. These can be seen when they soar above the high mountaintops and glide in circles. From the ground, they are easy to recognize by their color, completely black, except for a white "collar".

Huemul (deer), pumas, pudu, foxes and woodpeckers can be also seen. These are some of the unobtrusive inhabitants of the area.

To the east, reduced rainfall creates a landscape of ravines and practically dry plateaus, with a total predominance of the Patagonian steppe. This is the kingdom of yellow and orange grasses, typical of the westernmost humid area of the steppe. There foxes, pumas and guanacos wander around, together with birds of prey, such as the cinereous harrier and the American kestrel, typical birds of this area.

On the cliffs of some of the Nahuel Huapi islands, there is a population of blue-eyed cormorants, a really curious fact, as this is preferentially a seagoing species. It is also common to see kelp gulls following the boats.

One of the typical fauna species of the region is the huillín, a meat-eating mammal that has its main population in this park in Argentina. This is a native otter that lives on the shores of lakes, lagoons, rivers and streams. It has a longish body covered in brown fur, highlighted with reddish or orange hues, short legs and a long tail.

Another interesting species is the colonial tuco-tuco. This is a rodent that lives in underground warrens and its natural distribution is limited to Nahuel Huapi National Park.




FAUNA IN CALAFATE


Calafate Nature ...

Los Glaciares National Park hosts animal species typical of the sub-Antarctic forest and the steppe. Among these we may mention the condor, the black-chested buzzard eagle, the lesser rhea, the guanaco and the puma (cougar or mountain lion), among many others, including abundant bird life.


MAMMALS
There is a limited amount of information on the mammals inhabiting the area. What there is comes from park ranger reports and some old studies on middling to large size mammals, plus circumstantial data on some of the species.

Patagonia Pictures - RED FOX - Nature in PatagoniaAs well as the species mentioned above, we have the European hare, the red fox and, to a far lesser extent, the gray fox, the gato del pajonal and the gato montés (mountain cat or lynx).

The Park has some surviving and apparently isolated populations of huemul (Hippocamelus bisulcus). A recent study of this quadruped has established the presence of an important population in the Mascarello river valley and the western part of Lake Viedma, between Viedma Lagoon and Seno Moyano (Viedma Channel).

In some of these areas it is also possible to find the chinchillón anaranjado (orange colored chinchilla, or by its scientific name Lagidium Wolffsohni), a very rarely found species.

It is also common to find domestic species such as horses and cows that have gone wild. The latter are quite abundant in some areas.

Patagonia Pictures - HORSES - Nature in PatagoniaA major mammal population is that of horses, totaling some 15 thousand individuals only in the area populated by huemul in the Mascarello valley. This situation is a problem for the experts, because any sudden drop in the horse population would leave the huemul at the mercy of the pumas.


BIRDS
Information available on the Park's birdlife is very recent, for the most part dating from after 1980. However, it is quite complete. Up to the moment some 100 different species of birds have been registered as inhabiting the area.

Among this significant diversity are species that are considered to be specially valuable for conservation, such as the lesser rhea or "short ñandú" (Pterocnemia pennata), the condor (Vultur gryphus), the torrent duck (Merganetta armata), the white-throated caracara (Polyborus albogularis) and the white-bridled finch (Melanodera melanodera).

Of similarly significant density is the population of black-chested buzzard-eagle (Geranoaetus melanoleucus), mainly in the northern area of the Park. The rivers Fitz Roy and De las Vueltas have a large population of torrent ducks, concentrated in permanently resident family groups.

Some species that are hardly ever found in such southern areas have been recorded in some humid areas in the Park, for example the yellow-winged blackbird (Agelaius thilius) and the spectacled tyrant (Hymenops percpicillata).

These species have been observed in the Viedma lake Tunnel bay area, north of the Park, and in the Puerto Bandera "lagoons", within provincial territory on the edge of the Park.

Another species that is present and nests on the shores of lakes and lagoons in the Park is the Magellanic oystercatcher (Haematopus leucipodus).


FISH
In the lakes and lagoons around El Calafate, especially Argentino and Viedma, may be found two species of introduced salmonids: the rainbow trout (Onchorhynchus mikiss) and the lake trout (Christivomer namaycush).

Other species that have been recorded are:

Puyen (Galaxias maculatus) in Lake Argentino.
Perca (Perch or Percichthys vinciguerrae) in Lake Argentino and Lake Viedma.

As well as the species that have been confirmed, some others can be assumed to inhabit the surrounding watercourses:

Peladilla (Aplochiton zebra) - it has been recorded in Lake Toro (Torres del Paine National Park, Chile).
Peladilla (Aplochiton taeniatus), also in Lake Toro.
Puyen (Galaxias platei) - it inhabits the lakes of Paine Range.


AMPHIBIANS AND REPTILES
The Santa Cruz area, including the district of El Calafate, is considerably depleted as regards its amphibian and reptile populations.

Of the 60 Patagonian species recorded to date, there are 56 in the northern and 13 in the southern area, of which 9 are common to both. However only four are native to the southern area.

Of them all, the commonest are the lizards, that are mainly found in the grasslands far from the shore of the lake in the Punta Avellaneda area.




FAUNA IN PUERTO MADRYN


Puerto Madryn Nature ...

Puerto Madryn is a natural reservoir of different fauna species. Here, and in the different peninsulas, bays and points strewn around its shores, the traveler will thrill to the sight of a southern right whale, an orca, elephant seals or southern sea lions.

In the protected nature reserve of Península Valdés, World Natural Heritage, 100 kilometers away from the city, a tryst with the southern right whale is a once-only experience, and if you're in luck, you will also thrill to the sight of an orca.

Throughout the different excursions you will also meet up with land fauna: guanacos, choiques, maras (Patagonian hares) and Argentine gray foxes, each in its respective habitat. On forbidding trails you will experience the vastness of the steppe, and will have the chance of deepening your knowledge of Patagonian wildlife by taking information tours led by experienced local guides.

SOUTHERN RIGHT WHALE
The Nuevo and San José gulfs that surround Península Valdés, are the chosen spots for the southern right whale to give birth to and suckle its young.

These giants take over this portion of the South Atlantic from June to December.

This is when the deep blue waters begin to speckle with black, a sign that the whales have arrived. Be ready to witness an unequaled spectacle for around seven whole months: ocean acrobatics and scenes of tenderness between mothers and their young.

Every year some 600 animals gather here, although the total population of the Península Valdés area is estimated at 1,200.

The southern right whale (Eubalaena australis) was declared Natural Monument by Law N° 23094, and its current population, distributed among all the southern hemisphere temperate and sub-Antarctic seas does not number over 4,000.

It is a cetacean belonging to the sub-order of mysticetae that possesses in lieu of teeth corneous plates known as barbs or balaenae.

Most of them present ventral furrows and dorsal fins, but the right whale lacks both. Its jaw is long and narrow, causing its head to take up almost one quarter of its total body length.

In some areas on its head it shows a cluster of callous-like growths. These are populated by a large number of parasitic crustaceans. At the top of its head there are two "spiracles" (breathing holes) a structure analogous to our nose.

One of the southern right whale's most salient features is the way they expel their breath: when they breathe out, two streams of fine spray form a "V" shape that can be seen for miles around.

It feeds basically on crustacean plankton.

This whale species bears a single calf approximately once every three years. Pregnancy lasts twelve months and the calf is suckled for two years.

When the calves are born they measure between 3 and 5 ½ meters in length and weigh around 3 tons. During the first two months they grow at the rate of 35 millimeters per day, and as adults reach 12 to 16 meters length, weighing between 50 and 55 tons.

The first stage of adulthood is between 7 and 17 years of age. The females reach 13 meters in length when they achieve sexual maturity, the males grow more slowly.

A curious fact about the life of these marine mammals is their feeding habits. They gain weight by feeding on microscopic food that they filter through the barbs lining their mouth. They have no teeth and simply trap the krill and plankton they feed on by forcing sea water through their barbs.

Argentina has protected the right whale since 1935. In 1946 it became a member of the International Whale Committee. In 1994 the 46th meeting of the IWC took place, defining the standards of protection to be enforced in the Southern Sanctuary.

Whale sighting trips
Whale sighting is an unforgettable experience. It consists of a one-hour boat trip taking visitors within meters of these animals.

The trip is only a viewing one. You are not allowed to touch or approach them too closely. In any event, just being afloat with these monsters around you is an impressive experience.

Most of the ships that take visitors on this excursion leave from the small town of Puerto Pirámides.

The adventure starts when you follow the coast in both directions for a few kilometers before heading a few miles into the open water to meet the whales. When the boat is far enough from the shore, the engines are turned off and, for a moment there is absolute silence, punctuated only by the cries of penguins and seagulls.

Sailing along the coast also enables you to view the colonies of cormorants and other species belonging to the abundant avian coastal fauna. The first stop is usually in La Lobería, that is directly opposite Puerto Pirámides, and has a population of 2,000 southern sea lions.

After a few minutes and only a few meters from the coast, you get to the area where the whales are. The boat slowly approaches them and then, suddenly, when everyone in the boat is in a state of eager expectation, a silvery white object leaps out of the water alongside the boat. Then one hears the heavy slap of a body on the sea: the whales are here!

That is when the engine of the boat is turned off so as not to disturb the mammals. For a moment, only nature seems to exist.

The whale slowly approaches, placing its skin at hand's-length. Gradually, as it emerges, one realizes that it is considerably longer than the boat. It is an impressive creature. Now and then it makes a characteristic noise that blends with the sound of the wind on the sea.

The open sky is the only witness to the scene, and the cliffs provide an imposing backdrop.

Sighting season
Whale sighting season on the shores of Puerto Madryn in Chubut province lasts usually from June through December. The best chances of good sightings are in September and October.

The sighting of the southern right whale is a wonderful spectacle that repeats and gets better every year. This boating adventure starts from Puerto Pirámides. There are six firms authorized to do this trip, and these strictly follow the rules that have been established in order not to interfere with the whales' behavior.

Restrictions
Excesses committed both by scuba divers and sighting vessels have prompted Chubut province authorities to strictly regulate sailing and scuba diving activities in the whale season.

The rule is categorical: all activities are forbidden in the protected areas.

Both the fishermen and the scuba divers have to hire authorized operators or guides to carry out their activities. Also, the appearance of a marine mammal in any area where an activity is taking place forces the suspension of the activity.

Coastal diving activity is limited to skin-diving or snorkeling (using only air from one's lungs, without using oxygen tanks), and at a distance of more than 100 meters from any of the protected species.

For sport divers there is also an obligation to register at the Istmo Florentino Ameghino control point. There they are informed of this rule and have to sign a letter of agreement. They must also register in the Navy Prefecture (Coast Guard) office in Puerto Pirámides.


MAGELLANIC PENGUIN
In 1979, the province of Chubut created a 21 hectare reserve in Punta Tombo, 181 kilometers from Puerto Madryn, in order to protect Magellanic penguins (Spheniscus magellanicus).

Here one finds one of the world's most varied colonies of sea birds, plus the largest continental penguin colony outside the Antarctic. It has a population of over 500,000 birds in the months of September and April.

The penguins build their nests under bushes, in caves and in the open. The caves are found most frequently in the coastal areas where the soil is easier to dig, and they return year after year to the same nesting spots.

The males are sometimes larger than the females and have stronger and longer beaks. Both partners defend their nest, and take turns brooding and feeding the chicks with fish and squid.

Most of their life is spent in the ocean, where they even sleep. In winter they can swim up the coast to Río de Janeiro (Brazil), on a 3,000 kilometer voyage.

They are able to swim steadily at 8 kilometers per hour, using their fins to propel themselves and their feet as rudders. During February thousands of overgrown molting youngsters may be seen on the beach.

Marine predators such as the giant petrel and the killer whale lurk on the shoreline waiting to feed on young and ailing penguins.


ORCA (KILLER WHALES)
Orcas (Orcinus orca) are mammals belonging to the order of the cetaceans. In contrast with other whales, they have teeth. They may be seen in Chubut between February and April and from October to November.

They most frequently appear in Punta Norte, Caleta Valdés and Golfo San José, on the Valdés peninsula.

They are evenly black in color, with a white belly and a characteristic back fin with a white spot behind it that is an individual identification feature.

Their length varies between 8 and 9.5 meters. Males weigh 9 tons and females around 5. They propel themselves using their powerful tailfin, balancing and changing direction with their pectoral fins when feeding along the coastline.

They are wrongly considered to be ravenous predators (so-called "Killer Whales") due to their feeding habits that include not only fish but also other sea mammals such as sea lions, sea turtles, seals, sharks and even penguins.

This creature hunts for food and shares its catch with its family.


SOUTHERN ELEPHANT SEALS
Península Valdés offers visitors the chance to view southern elephant seals (Mirounga leonina) without having to travel to remote island areas, because this is the only continental colony of this species.

The southern elephant seal species has sub-Antarctic distribution, with an estimated population of 700,000 individuals, of which 20,000 arrive at Península Valdés between August and March to mate and molt.

This animal belongs to the seal family, and differs from other pinnipeds due to the absence of the outer ear, and because their lower limbs are pointed backwards, making it necessary for them to drag themselves on land.

The males have a highly developed proboscis (like an elephant's trunk) on their snouts, and are much larger than the females, reaching 5 meters in length and weighing up to 3 or 4 tons. The females only reach about three meters in length and weigh less than one ton.

The pups when born weigh 45 kilos and are pitch black, but become gray after 23 to 30 days of suckling and rapidly gain weight to around 250 or 300 kilos. Elephant seals are extremely polygamous.

By late August, the first males arrive to form their harems. The females arrive on the coast at the beginning of September, giving birth to a pup on average 5 days later.

During lactation the mothers fast and consume their whole store of fat. After they finish suckling their young, elephant seals feed out at sea for two months to regain their weight.

They seek their food at an average depth of 400 meters, and have been known to dive to 1,500 meters while hunting. Elephant seals spend 90% of their seagoing life under water. After December, they return to the coast for five months to molt.


SOUTHERN SEA LION
The southern sea lion (Otaria flevescens) is a species widely distributed on the South American Atlantic and Pacific coastline, from south Brazil up to Perú, and is commonly seen during the whole year on Península Valdés.

This is a pinniped that belongs to the otter family; it is able to walk on land using its front and back fins.

The dark brown males may be distinguished from the females by their mane, reaching 2.3 meters in length and weighing up to 350 kilos. The females only measure 1.8 meters and weigh around 100 kilos.

The pups, that are born from late December to late January, are black in color. They bleat like lambs and weigh around 13 kilos. After a year of suckling, they barely double their weight.

The sea lions have a short migration between the colonies of Golfo Nuevo and Península Valdés. In mating season, the males go to Punta Pirámides, near Puerto Pirámides and Punta Norte. Outside mating season, from April to November, they may be seen at other colony locations.

One of the most important of these is the Punta Loma seal colony (provincial reserve), locate 17 kilometers from Puerto Madryn. The juvenile, non-reproducing adults are found at this colony all year round, and are joined as from April by the animals migrating from Puerto Pirámides.


SEA BIRDS
Península Valdés is one of the main locations on the Patagonian coast featuring abundant and varied sea bird life.

On De los Pájaros Island , with an area of 2.2 hectares, there is a great variety of birds.

Recent research identified six marine and coastal nesting species: the Magellanic penguin (Spheniscus magellanicus), the rock cormorant (Phalacrocorax magellanicus), the neotropic cormorant (Phalacrocorax olivaceus), the kelp gull (Larus dominicanus), the great egret (Casmerodius albus) and the black-crowned night-heron (Nycticorax nycticorax).


GUANACO
Patagonia Pictures - GUANACOS - Nature in PatagoniaThe guanaco (Lama guanicoe) is the largest and most widely distributed of the South American camelids. It inhabits one of the planet's most hostile environments: from the hot, windy lands of southern Peru to the semi-arid steppe of Argentine Patagonia.

Before contact with Europeans, some 8 thousand years ago, this animal was a vital resource for the survival of the native cultures that poured into the area.

Images of guanacos are found everywhere in cave paintings and rock engravings.

Currently this species is not endangered on the continent. However, hunting and climate and habitat changes have caused a drop in its population.

This fact has spurred the adoption of integrated conservation programs.

An adult guanaco reaches 1.75 meters in height, and weighs between 80 and 120 kilos. It has pads on its feet that prevent trampling damage to ground vegetation. It has highly mobile and sensitive lips, enabling it to select its food among thorny and woody type vegetation.

Mating season is from November to February, after the young are born. The newborn foals weigh between 8 and 15 kilos. The guanaco is a diurnal animal with unique social behavior.

The family groups vary from 2 to 30 members. Due to its light reddish-brown fur and lighter areas around the lips and inner portion of the limbs, it is one of the easiest species to view on the fauna reserves, especially those of Valdés and Tombo.

Some 600,000 guanacos are thought to inhabit South America. Of this total, 94% is in Argentina, 5% in Chile and the remaining 1% in Peru and Bolivia. The highest densities are currently located in the southern tip of Patagonia.

Recent research indicates that approximately 12,400 guanacos inhabit the northeast of Chubut, with an average population density of around one guanaco per square kilometer. Península Valdés houses some 2,200 animals in 4,000 square kilometers.


LESSER RHEA (CHOIQUE)
The lesser rhea (Pterocnemia pennata) is an enormous bird that one almost always sees along the way on one's walks through Península Valdés. It is one of the two "South American ostriches" with three toes, unlike their African relative, that has two.

The lesser rhea is unmistakable. A good runner on the Patagonian steppe, it reaches 1.10 meters height, and is smaller than the wet pampas variety, the greater rhea (ñandú), with long legs and neck, a small head and without rigid tail and wing feathers.

Its head, neck and back are a dark brownish gray in color. Unlike the greater rhea, it has feathers on the top of its torso. It may be found in groups. They are polygamous, and the male incubates and guards the enormous eggs.

Their nests are built on the ground. There they lay several cream-colored eggs that will later hatch, and the "charitos" (as the chicks are locally called), will follow their father during almost the whole summer. In winter, mixed groups of males, females and juveniles are formed.


ARGENTINE GRAY FOX
The Argentine gray fox (Pseudalopex griseus) is a South American canine species distributed over the herbaceous and bushy steppes of Patagonia outside the Andes. It has long prominent canines, and its molars and pre-molars form the so-called "butcher's knife" , a sharp edge that is used for slicing the meat off its prey.

Although these foxes are carnivorous, they have a wide-ranging diet, and also eat fruit and insects at those times of year when rodents are scarce and they are unable to trap birds.

They weigh no more than 4 kilos and measure 90 centimeters in total length. They have a clearly visible tail that is dark brown on the ventral side and black elsewhere. Their snout is sharp and they have large triangular ears.

Their reproductive season starts in August. Males and females are often seen together only in September and October. After 58 days of pregnancy, in early November they start giving birth to litters of 3 to 5 pups that follow their mothers all summer up to the first months of fall.

On Península Valdés the gray fox is an animal often seen near the wildlife rangers' dwellings. They stay near the rangers because they feel protected by them and get extra rations from them also.


OTHER SPECIES
Other species inhabiting Puerto Madryn and Península Valdés are the mara (Patagonian hare), the piche patagónico, the southern crested-caracara (carancho), the upland goose, the elegant crested-tinamou, the rock cormorant, the kelp gull, the snowy egret, the American oystercatcher, the plovers, the dotterels and the southern lapwing.

FAUNA IN SAN MARTIN DE LOS ANDES


San Martin de los Andes Nature ...

As regards the fauna, there are records of 165 autochthonous vertebrates: 102 birds, 11 reptiles, 9 amphibians, 33 mammals and 10 fish.

Among the species present in Lanín National Park, the following are considered to be of "special value":


Fish

Among the fish, the exotic salmonids which were sown in the past for sport purposes have pushed out autochthonous fish such as the criolla trout, the Patagonian pejerrey and the puyén.

Autochthonous fish
Patagonian pejerrey
Perch or criolla trout

Exotic fish
Silver or rainbow trout
Stream or fontilanis trout
Brown trout


Mammals

The pudú can be found in the dense areas of the wood. It is a small deer with reduced antlers and his body is well adapted to move in this environment. Together with the huillín, an otter exclusive of Chile and Argentina, they are two of the mammals in danger of extinction which are protected by this National Park.

Autochthonous mammals
Patagonia Pictures - RED FOX - Nature in PatagoniaThe most outstanding species are the pudú, the puma, the red fox, the small gray fox, the wild monkey and several rodent species. Among rodents, the tuco-tuco (Ctenomys maulinus), abundant in Chile, in Argentina is found only in Lanín National Park. The same happens with the degu (Octodon bridgesi), which has only been registered in Argentina in the region of Curruhué.
The huillín, one of the species in danger of extinction, has practically disappeared in the area. The situation of the huemul (deer), also considered in danger of extinction, seems to be quite critical as there are no recent records. However, experts have not completed the search in all the areas potentially suitable for this deer.
The situation of the huiña cat (Felis gigna), an endemic species from the Sub-Antarctic forest which has been classified as vulnerable in the country, is also uncertain.

HUIÑA CAT (Felis gigna)
It has long, dense and slightly woolen hair, with numerous spots closely grouped against a pale reddish-cream background. Some darker or even black specimens have also been found. It is smaller than the regular domestic cat, and it is found only in a limited portion of the Patagonian forest.

PUDU (Pudu pudu)
This species used to be included in the Red Book of Threatened Species, but it no longer is. There are protected communities in the South Park. It is the smallest of all the deer, between 40 and 50 cm tall and 90 cm wide. It is reddish and males differ from females in their small non-branching antlers, which are renewed every year in winter.
The natural habitat of this species is the vegetation of the Andean forest, in particular the valdivian forest.

PUMA (Felis concolor)
This feline species, widely spread all over Argentina, includes seven sub-species. It is gray or brown, small headed, with a long and flexible body, long tail and rounded ears. An adult male can be 1.5 m long and weigh 35 kg. It is found in a wide range of habitats, from forests to open areas. It has mainly night habits and it is purely carnivore, feeding on a great variety of prey.

GUANACO (Lama guanicoe)
This beautiful camel is widely spread throughout South America, in various habitats which include thorny scrubs, steppes, desserts, coastal areas, mountains and hills. It is the tallest land mammal in Argentina. Its hair is long, thick, and ocher, yellowish or cinnamon-colored. It has big eyes, long eyelashes, moving harelips and long pointed ears. It can be 1,85 m long and 1,10 m tall including its withers. It feeds on a great variety of plants.
Argentina is home to 96 % of all the existing guanacos in the world (about 500,000).

HUEMUL (Hippocamelus bisulcus)
This stout deer can be 1 m tall at the withers. Its relatively short legs make it look shorter and fatter than other deer. The male huemul has branching antlers. It has thick coffee-colored hair, which gets lighter in summer becoming yellowish-gray. Its ears and tail are over 20 cm long. It lives in mountainous wooded land and in higher places in the summer. It is a clearly territorial, herbivore and lonely animal. It is rarely seen in family groups.

WILD MONKEY (Dromiciops australis)
As a matter of fact, there are no real monkeys in these southern woods. The so-called " wild monkey" is actually a marsupial similar to weasels, kangaroos and koala bears. The birth of its cubs takes place at an early stage as their development continues out of the mother's womb, in the marsupial pouch. It is a small weasel, 10 to 12 cm long plus a tail of similar length.
It has dense and soft hair, a pointed muzzle and sharp teeth. It lives in damp woods and remains in the holes of old trees during the winter. It is the only existing representative of the Microbioteridos family

Exotic mammals
Due to their wide distribution, it is worth mentioning the European hare, the wild boar and the red deer. More recently, the European rabbit and the North American mink have been added and are spreading fast.

Patagonia Pictures - TORRENT DUCK - Nature in PatagoniaRegarding autochthonous birds, there is a wide representation of the Andean Patagonian species. Among the species indigenous to aquatic environments, it is worth mentioning the presence of the torrent duck (Merganetta armata), which is considered "rare" in the country. Other important bird communities are: Magellanic woodpeckers (Campephilus magellanicus), Chilean pigeons (Columba araucana), ochre-flanked tapaculos (Eugralla paradoxa) and condors (Vultur gryphus), among others.

Among reptiles, several species of lizards are very common in the region, such as the green- headed one (Liolaemus chilensis) and the orange-bellied one (Liolaemus pictus), which are distributed all throughout the protected area. Likewise, in the northern area of the Park, the iridescent lizard (Liolaemus tenuis) is found, registered also in Chile and in the center-west Andean region of Neuquén.

As regards native fish, there are the criolla trout or perch, the Patagonian pejerrey, the puyén and the "velvety catfish". Before the creation of the National Park, the main lakes and rivers had been sown -for sport purposes- with exotic species such as the rainbow trout, the brown trout and the stream trout. In all the river basins there are macro-invertebrates such as freshwater crabs and prawns which play a very important role in these ecosystems.

RED DEER (Cervus elaphus)
It is an exotic species of European origin. Due to its acute smell and hearing, its hunting becomes really difficult. That is why, it is a favorite prey for hunters, who consider males' antlers a valuable trophy. It lives mainly in high mountainous wooded regions. It has reddish hair and highly branched antlers, which are lost and renewed every year. During the rut, the males' necks look more hairy and swollen, as they get ready to mate with more than one female.

WILD BOAR (Sus scrofa)
