Puma, Mountain Lion (Felis concolor patagonica) Pumas live solitarily in the mountainous areas of the Americas. It feeds mainly on rodents and occasionally feeds on birds, guanacos (in the llama family) and deer. Opportunistic hunters, pumas will eat anything they can catch. A female puma can kill a bull elk seven times its own size, crushing its trachea with its teeth. They have also been reported to prey on livestock. Pumas avoid humans and incidents of them killing people are extremely rare. Argentinean folk tales emphasize the harmless nature of the puma. Puma can be as long as nine feet (2.8 meters) and weigh 170 lbs (80 kg).

Huemul (Hippocamelus bisulus) Though the huemul is one of Chile's national symbols, it is rare and poorly studied. It lives isolated in the mountainous temperate rain forests of South America between approximately 1300 feet (440 meters) and 4000 feet (1,300 meters) in elevation. Its world population is believed to number 1,000 - 2,000. In Chile, it is classified as an endangered species. Its skin color varies with the seasons between a dark brown to a lighter brown or yellow with grey stripes. The male body can reach a length of six feet (two meters), with a short tail. It can weigh up to 250 lbs (120 kg), though the females are generally smaller.

Pudu (Pudu pudu) The smallest deer of the Americas, pudus live in dense thickets of the rainforests between the latitudes of Curicó and Aysén of Chile. Pudus are solitary and nocturnal, thus rarely encountered. The male and female are only together during the mating season. They can weigh up to 25lbs (10 kg) and can live to be nine years old.

Jabalí (Sus scrofa) Commonly known in English as a wild boar, jabalí are found in the mountainous forest regions of the Americas, New Zealand, Asia, Australia, Africa and Europe. They are nocturnal omnivores with a consistent diet of roots, tubers and insects, which they dig up. Though they have terrible vision, they have a keen sense of smell and excellent hearing. The males have large teeth, which grow throughout their lives. Jabalí are found living in groups of up to 30, but the older males tend be solitary. During mating season, the male jabalí battles ferociously to mate with the females. Jabalís grow to a height of 2 1/2 feet (80 cm) and can weigh up to 250 lbs. (120 kg).

Condor (Vultur gryphus) The Andean condor is the largest bird of prey in the world. Condors are usually seen in the air in numbers ranging from one to sixty or more. Its range is now reduced to only several South American countries including Chile. They roost and nest in the mountains, although not usually above 18,000 feet (5,500 meters). Their normal food is carrion, dead, dying or sometimes newborn animals. Condors have heads that are bare of feathers - an adaptation for feeding on carcasses. Both parents incubate and care for the young. The chick cannot fly for about five months, and not for any distance until seven months. By ten to twelve months of age the young condor can fly well enough to forage, but the parents still feed it. Young are produced only every other year, and usually only one at a time. A condor reaches sexual maturity only after six years of age. Condors have commonly been killed for their feathers (used for decoration) as well as for being considered pests. Some Indian religions considered a hunted condor a rite of passage for men. In captivity condors have reached ages in excess of 70 years. Condors have wingspans exceeding 12 feet (four meters) and weigh up to 25 lbs. (11 kg).

Coho Salmon - Silver Salmon (Oncorhynchus kisutch) Coho salmon migrate from the ocean into the fresh water streams and rivers of their birth. They are semelparous, which means they spawn only once and then die. Coho salmon spend the first half of their life rearing in streams and small freshwater tributaries. The remainder of the life cycle is spent foraging in marine waters of the Pacific Ocean prior to returning to their stream of origin to spawn and die. Most adults are three year-old fish, however, some precocious males known as "jacks" return as two-year old spawners. A returning adult may measure more than two feet in length and weigh an average of eight pounds.

Chinook Salmon - King Salmon (Oncorhynchus tshawytscha) Chinook salmon are the largest of any salmon, with adults often weighing more than 40 pounds. Like the Coho, Chinook salmon migrate from the ocean to fresh water streams and rivers of their birth and are semelparous, which means they spawn only once and then die. Chinook salmon spend one to eight years at sea before returning to natal streams to spawn.

Steelhead and Rainbow Trout (Oncorhynchus mykiss) Rainbow trout and steelhead are the same species of fish. The two names reflect different life histories. Rainbow trout live a non-anadromous life, meaning they live their whole lives in fresh water. Steelhead trout live an anadromous life, which means they return from the ocean to fresh water to spawn. Both steelhead and rainbow trout are born in fresh water streams, where they spend their first one to four years of life. Similar to salmon, steelhead migrate to the ocean where most of their growth occurs while the rainbow never leaves. After spending between one to four growing seasons in the ocean, steelhead return to their native fresh water stream to spawn. Unlike salmon, steelhead do not necessarily die after spawning and are able to spawn more than once.

Brown Trout (Salmo Trutta) Brown trout naturally occur throughout Europe and western Asia. Introduced throughout the world, they were first placed in Canadian waters in 1890. Today they are found in rivers, lakes and coastal areas in much of North and South America. Brown trout can vary considerably in size and coloration depending on the waters they inhabit and the available food. Most river brown trout spawn during early winter migrating upstream to the shallow gravel runs of the main river or the feeder streams. Later, they drop back downstream. Through spring, brown trout are solitary and will compete with other browns for a territorial eddy. The same browns can be found foraging in the same eddies for days and sometimes even years. A brown trout can weigh up to 35lbs.

It is believed that rainbow and brown trout eggs were first imported from New York and stocked successfully in Lago Naguel Huapi, Argentina and other lakes in the early 1900's
