White-faced Saki (Pithecia pithecia)

The White-faced Saki inhabits northeastern South America, including eastern Venezuela, Guyana, Suriname, French Guiana, and northeastern Brazil north of the Amazon.

These primates reach lengths of 30 to 48 cm, with a bushy tail as long as their body. They weigh approximately 1.5 to 1.8 kg. Their hind legs are significantly longer than their front legs, and their tail is not prehensile.

Their fur is long and shaggy. Males are black with a contrasting white or reddish face and throat. Females have black-gray or gray-brown fur, resembling other saki species, and have two white stripes extending from their nostrils down and outward along the lines of their mouth folds.

White-faced Sakis are active during the day, rarely descending to the ground, and typically dwell in the middle or lower canopy levels.

Fun Fact: White-faced Sakis have a unique way of moving through the trees.

They use their powerful hind legs to make impressive leaps, covering distances of up to 6 meters (20 feet) in a single bound! 🌳🐒

House Centipede: A Helpful Creature!

The house centipede (Scutigera coleoptrata) is completely harmless to humans. Yet, many kill this beneficial insect at first sight, fearing its speed and appearance. Interestingly, in some southern countries, these centipedes are cherished and protected.

An adult house centipede grows to 35—60 mm in length. Its body is yellowish-gray or brown with three reddish-violet or bluish stripes along its length, and its legs are also striped.

Like all arthropods, the house centipede has an external skeleton made of chitin and sclerotin. Its body is flattened and divided into 15 segments, each bearing a pair of legs.

Why are house centipedes beneficial? You guessed it! They hunt flies, cockroaches, termites, spiders, silverfish, fleas, moths, and other small arthropods. House centipedes kill their prey by injecting venom and then consume them.

Honey Possum (Tarsipes rostratus) - the only fully nectar-feeding mammal (except for some bats).

Its snout is elongated into a trunk-like structure, making up about two-thirds of its head length. The tongue, long and thin, can extend 2.5 cm from the mouth, acting like a brush to collect pollen, while the elongated snout serves as a tube to suck up nectar. The genus name "rostratus" translates from Latin to "beak-like".

Honey possums are smaller than mice: body length is 7-8 cm, tail length is 10 cm, and weight is only 13-17 g.

Fun Fact: Honey possums are active year-round, but their activity peaks during the flowering season of their favorite plants, typically from July to November.

They are found only in the southwestern coastal region of Western Australia, but are quite common in this small range. 🌺🐾

Fire Pleuropoma Platymma tweediei - one of the rarest snail species in the world, the largest snail of the Malaysian Peninsula, living exclusively in wet mountain forests. Its shell can reach up to 7 cm in diameter.

This snail species is characterized by a black shell and a bright red or orange body.

The habitat of these snails is greatly limited. They can only be found in a specific mountainous area, over 1000 meters above sea level, with high humidity and cold air. Due to the abundance of streams and springs, this area is often shrouded in mist. Summer temperatures rarely exceed 27°C, while winter temperatures can drop below 10°C.

Unlike other gastropods, the red snail is active during the day. This behavior likely indicates an adaptation to temperature fluctuations at night.

Fun Fact: The vibrant coloration of the Fire Pleuropoma serves as a warning to potential predators about its toxicity. 🌈🐌

Luna Moth ("Lunar Butterfly" or "Lunar Moth")

The Luna Moth, Actias luna, is a part of the Saturniidae family, known as giant silk moths. It is native to North America, found in Canada, as well as Mexico and Guatemala.

This large moth has a wingspan of 8 to 11.5 cm. They are crepuscular and nocturnal, with males being more active than females.

Interestingly, these moths have a rudimentary mouthpart and do not eat. They live off the fat reserves accumulated during their caterpillar stage.

Fun Fact: The beautiful green color of the Luna Moth is a result of a pigment called "luna-brin," which is unique to this species. 🌙🦋

Pileated Woodpecker (Dryocopus pileatus) - the largest woodpecker in North America, pecks wood 12,000 times a day at a speed of 20 strikes per second. For humans, this is equivalent to hitting your face against a wall at 25 km/h.

The bird has a sturdy skull made of spongy bone, and cartilage at the base of the lower jaw, attached to the skull by powerful muscles, partially softens the blows, which barely affect its brain.

Additional protection is provided by the fact that the woodpecker's brain is relatively small compared to its size, making it more resistant to shaking. Thus, the woodpecker can turn its entire body mass into a "hammer," only worrying about its eyes, which close with a thickened membrane during pecking.

Fun Fact: The Pileated Woodpecker's loud drumming can be heard from a distance of over a kilometer away! 🌲🐦

The Ghost of the Forest

The Kagu, scientifically known as Rhynochetos jubatus, is a unique bird found only on a small island in the world. The indigenous people of New Caledonia call it the "Ghost of the Forest" due to its elusive nature and exclusive habitat.

This bird, belonging to the crane family, stands about half a meter tall and weighs between 0.7 to 1.2 kg. Its body is stocky, resembling a chicken, with a small head on a short neck. A distinctive feature is its long (12 cm) crest, which becomes prominent only when the bird is excited, transforming into a bushy mohawk.

Kagus are territorial, with each family occupying an area of 10 to 30 hectares. They rest during the day, hiding in rocky crevices or under the roots of uprooted trees, and become active at dusk.

Interesting Fact: The Kagu is known for its unique call, which sounds like a whistle and can be heard echoing through the forest at night.

Southern Caracara (Caracara plancus)

The Southern Caracara, also known as the Carancha, inhabits the open spaces of South America. It is one of the largest birds in the falcon family, second only to the Gyrfalcon in size and weight. The body length ranges from 55-65 cm, and it can weigh up to 1.5 kg.

🍽️ Its diet is varied, from insects and worms to small mammals, frogs, and lizards. It often feeds on carrion and steals prey from other birds.

🌎 The behavior of the Caracara is quite unusual compared to other falcons. You can often see this bird walking on the ground in search of food, using its long legs to move around.

🤝 In addition to preferring to walk rather than fly, these birds also form close bonds with their own kind. In their free time, they prefer not to soar in the air—this is not for the Caracara.

💡 Fun Fact: Caracaras are known to use tools, such as using rocks to break open eggs, a rare behavior among birds!

Corncrake (Crex crex) – a medium-sized bird from the rail family, known for its distinctive, crex-crex call, which gives it its Latin name. These birds are vocal from May to mid-summer, but remain silent for the rest of the year, especially during winter migration.

Corncrakes are reluctant to fly (usually only in extreme danger), covering just a few meters before landing again. However, their clumsiness in the air is compensated by their swift running and agility on the ground. They are excellent runners, confuse tracks, and hide skillfully, making it difficult for hunters to find their resting spots.

They feed on insects, spiders, mollusks, and occasionally small frogs, mammals, as well as seeds and green parts of various grasses and cereals, including crops.

Fun Fact: Corncrakes are known for their secretive nature and are often heard but rarely seen. Their population has declined significantly due to habitat loss, making them a species of conservation concern.

African Wild Dog (Lycaon pictus)

This unique canine resembles a hyena only by its black facial mask. It has a lean, light body, strong high legs, and large, oval-shaped ears that give its head a distinctive silhouette.

Body length is about a meter, shoulder height up to 78 cm, and weight varies between 18-36 kg, depending on whether the animal is fed or hungry. African wild dogs can eat up to 9 kg of meat in one sitting!

Once widespread in African savannas south of the Sahara, their range is now fragmented, mainly in national parks and untouched landscapes in Namibia, Botswana, Tanzania, Mozambique, Zimbabwe, and South Africa.

Fun Fact: African wild dogs are one of the most successful hunters, with a success rate of over 80%! 🐾

Glossy Ibis (Platalea leucorodia) - A Marsh Bird with a Unique Spoon-Shaped Bill!

The Glossy Ibis is a wading bird from the ibis family, reaching up to 1 meter in length, weighing 1.2-2 kg, with a wingspan of 115-135 cm. It's entirely white, with black bills and legs. During breeding season, they develop a crest on the back of their heads and a rusty patch at the base of their necks. Their most distinctive feature is their spoon-shaped bill, which they use to filter mud for food.

Did you know? The Glossy Ibis is known for its unique feeding technique. It sweeps its bill side-to-side in shallow water to catch small fish, crustaceans, and other aquatic creatures.

They nest in Southern Europe, Asia, and Northern Africa. In Europe, they winter in Central and Eastern Africa, while Asian populations migrate to India and China.

Glossy Ibis inhabit shallow waters, slow-moving rivers with muddy bottoms, and both freshwater and saline lakes. 🌊🐟

Marsh Cat (Reed Cat or Swamp Lynx) Felis chaus

The marsh cat is larger than any domestic cat (except for the Maine Coon): body length 60–90 cm and weight 8-12 kg.

It has a relatively short body, long legs, and a short tail (21–30 cm), with small tufts on its ears. Its color is yellow-brown, uniform, with a lighter underside. The marsh cat resembles a lynx.

Fun Fact: Marsh cats are excellent swimmers and are known to dive into water to catch prey or escape threats!

These elusive felines thrive in dense reeds, trostnik, and thorny bushes along low-lying riverbanks, lakes, and seas. They feed on birds, rodents, and hares. Once believed to harm hunting estates, they are now recognized for their ecological role.

🐾 Did you know? Marsh cats have a unique vocalization that sounds like a mix between a meow and a bark! 🐾

Bullfinch (Pyrrhula pyrrhula) - a songbird from the finch family, it appears in our view in winter as the most active bird of this time of year.

The bullfinch is slightly larger than a sparrow: body length 15–19 cm, wingspan 24–30 cm, weight 24–36 g. At first glance, its red cheeks, lower neck, belly, and sides stand out - the tone and intensity of the lower body's coloration depend on the subspecies and individual characteristics. The bird has a black cap that appears with age.

Bullfinches have a fast, undulating flight, and they move on the ground in jumps. The song of the bullfinch is a sad whistle "few" or "few". It is quite pleasant - a set of soft whistles, buzzing and creaking sounds.

Fun Fact: Bullfinches are known for their unique feeding behavior. They often feed on tree buds, especially in winter, which has earned them the nickname "bud eater". This behavior is quite unusual among songbirds and makes them a fascinating subject for birdwatchers.

Four-winged cuckoo Tapera naevia inhabits South America - from Mexico and Trinidad south to Bolivia and Argentina.

This bird holds a significant place in Brazilian folklore and is linked to the legend of Saci, a one-legged mulatto boy with holes in his hands, an incorrigible prankster who smokes a pipe.

One of Saci's magical abilities is the power to transform into the elusive bird, Matita-pere, whose melancholic song seems to come from nowhere...

Fun Fact: The four-winged cuckoo is known for its unique call, which resembles the sound of a squeaky wheelbarrow! 🎶🐦

European Bison (Bison bonasus) - the last representative of wild cattle in Europe.

All modern European bison descend from just 12 individuals that existed in the early 20th century in zoos and reserves. This raises an interesting question: what is the role of zoos in conservation?

The debate continues in scientific literature: are the European bison and the American bison separate species, or are they subspecies of one species?

Interestingly, while European bison and American bison share similarities in their paternal Y-chromosome, their maternal mitochondrial DNA tells a different story. The American bison is more closely related to the yak (Bos grunniens), while the European bison is closer to the aurochs (Bos primigenius).

Today's European bison are smaller than their ancestors and even smaller than one of the American bison subspecies, the wood bison. Adult male European bison from the Bialowieza Forest subspecies weigh between 400 and 900 kg.
