The birds species present at Huinay are characteristic for this area of Chile. By far the most common and obviously spotted species are the jotes (vultures – Cathartes aura and Coragyps atratus) that gather in large groups along the beach, roofs, boats, or whatever other perch they can find. Also common is a small caracara species, the tiuque (Milvago chimango), that one can often hear calling to one another in loud raspy voices. A larger species of caracara, the traro (Polyborus plancus), also flies in front of the station at times. A kingfisher (Ceryle torquata) often perches on our dock in the morning.
Other common species seen in fields are the queltehue (Vanellus chilensis) and the bandurria (Theristicus melanopis), both species ubiquitous to this region. Two species of hummingbirds (green-backed fircrown – Sephanoides sephaniodes and picaflor gigante – Patagona gigas) chase each other through the fuchsia foliage.
Large groups of the fío-fío (so named for its charismatic call, Elaenia albiceps) assault berry trees. Swallows (Tachycineta meyeni and Pygochelidon cyanoleuca) swoop over the water in the evening light. Further away from the edge of the water, a walk through the woods will inevitably contain an encounter with the chucao (Scelorchilus rubecula), an inquisitive and noisy little bird. Further up in the forests, a flock of green parrots (Enicognathus ferrugineus or E. leptorhynchus) may be heard squawking in the treetops. Near the top of the Cerro Tambor, huge condors (Vultur gryphus) circle in search of a meal.
Mammals
Mammalian diversity at Huinay is slim. Other than feral cats and livestock from the nearby township, it is rare to observe terrestrial mammals. Bats (Chiroptera) can be observed feeding at dusk.
Otters have been occasionally observed near the dock (either Lutra feline, the marine otter, or Lontra provocax, the river otter).
Sheltered in the rainforest lives the shy Pudú (Pudu pudu),a tiny monogamous deer not higher than 40cm. It is not uncommon during expeditions through the forest to find traces or excrement of Puma (Felis concolor); also present is the wildcat Lynchailurus colocolo. At higher altitudes, one might be lucky enough to encounter the viscacha (Lagidium viscaccia), a member of the chinchillidae family whistling from atop a rock.
An already deceased specimen of the endangered marsupial, Monito del Monte (Dromiciops gliroides) was found along the paths above the station, but live individuals have yet to be encountered.
Insects
There exists an extensive diversity of moths around the Comau Fjord. The fuchsia bushes are usually covered with bumble bees (Bombus spp.) and the domestic bees from the local apiculture hives. Various wasps can be encountered, as well as dragonflies and horseflies in the summertime.
Stick insects may reach as large as 15 cm.
Also some very exquisite species of beetles have been found.
Amphibians
Several types of amphibian species have been observed around the station. The symbol of the station, the darwin frog (Rhinoderma darwinii) is a rare treat to observe while walking through the surrounding forest. The marbled wood frog (Batrachyla antartandica) and the Nibaldo’s wood frog
(Batrachyla nibaldoi) are heard calling from the stream running nearby the dormitory building.
The treefrog Hylorina silvatica may be seen climbing a bush besides the paths in the station.
Reptiles
Lizards and skinks have both been found by hikers on paths above the station.
