Southern Cassowary


True Wild Life | Southern Cassowary | The Southern Cassowary is a large bird that lives in New Guinea and Australia. They are flightless, but equipped with a strong kick. Their numbers continue to decline because of disappearing tropical rainforests and hunting. The Southern Cassowary also known as Double-wattled Cassowary, Australian Cassowary or Two-wattled Cassowary.


In appearance, the Cassowary looks like a short, heavily-built, black and blue Emu, Dromaius novaehollandiae. Both species are indeed closely related, belonging to the family Casuariidae, and both are flightless. The female Southern Cassowary selects a male to breed with and then lays a clutch of large green eggs in a scrape in the ground lined with plant material. Once the eggs are laid, the male is left in charge of the incubation and chick-rearing duties, while the female moves away, and may even breed again with another male. During the breeding season, the parental males are very aggressive, and attacks on humans have been recorded at this time.


The Southern Cassowary feeds mostly on fruit that has fallen to the ground. The Southern Cassowary will also eat anything from snails to small dead mammals. Southern Cassowaries normally feed alone. If two males should meet, they have a stand off where both birds stand tall, fluff up their feathers and rumble at each other until one retreats. If a male and female meet, the male will move away, as the female is dominant.


In parts of its range the Southern Cassowary is still relatively common, but numbers are decreasing because of habitat clearance and collisions with cars. Their fruit diet means they are commonly sighted in commercial orchards and gardens with fruit bearing trees. Interestingly, citrus fruit is not usually eaten. They can also be dangerous if cornered.

Box Turtle


True Wild Life | Box Turtle | The box turtle or box tortoise is a genus of turtle native to North America. Box turtles are land dwelling creatures with high, domed shells, hence the "box" moniker.  Box turtles are found all over the world, and are generally found living in mossy areas of the forest, or other damp habitats.  They are very territorial, and sometimes spend their entire lives near their place of birth.


North American box turtles are omnivores with a very varied diet as box turtles "basically eat anything it can catch". Invertebrates (amongst others insects, earth worms, millipedes) form the principal component, but the diet also consists for a large part (reports range from 30-90%) of vegetation. The diet is amended with fruits (amongst others from cacti, apples and several species of berry), gastropods. While reports exist that during their first five to six years, box turtles are primarily carnivorous, while adults are mostly herbivorous, there is no scientific basis for such a difference. They are strong, sturdy animals, and usually grow to be about 6 inches long.  Box turtles are usually dark in coloring with some yellowish markings, and the male of the species have bright red eyes, longer tails, and their plastrons are indented.


Box turtles are endemic to North America. The widest distributed species is the common box turtle which is found in the United States (subspecies carolina, major, bauri, triunguis; South-Central, Eastern and South Eastern parts) and Mexico (subspecies yukatana and mexicana; Yucatán peninsula and North Eastern parts). The Ornate box turtle is endemic to the south-central and South Western parts of the U.S.  while the spotted box turtle is endemic to North-Western Mexico only. The coahuilan box turtle is only found in Cuatro Ciénegas Basin.

Great Spotted Kiwi


True Wild Life | Great Spotted Kiwi | The Great Spotted Kiwi, is a species of kiwi endemic to the South Island of New Zealand.  It is the largest of the kiwi.  There are about 22,000 Great Spotted Kiwis in total, almost all in the more mountainous parts of northwest Nelson, the northwest coast, and the Southern Alps. A minority live on islands.


Great Spotted Kiwi are nocturnal, and will sleep during the day in burrows. At night, they feed on invertebrates and will also eat plants. Great Spotted Kiwi breed between June and March. The egg is the largest of all birds in proportion to the size of the bird. Chicks take 75 to 85 days to hatch, and after hatching, they are abandoned by their parents.


Because adult Great Spotted Kiwis are large and powerful, they are able to fend off most predators that attack them, such as stoats, ferrets, weasels, pigs, brushtails and cats, all of which are invasive species in New Zealand. However, dogs are able to kill even adults. Stoats, ferrets, possums, cats and dogs will feed on the eggs and chicks, meaning most chicks die within their first five months of life. Once the Great Spotted Kiwi was also preyed upon by the Haast's Eagle, which is now extinct.

Yellow-margined Box Turtle


True Wild Life | Yellow-margined Box Turtle | The Chinese box turtle is a species of Asian box turtle with several names. Its common names include Chinese box turtle, 食蛇龜 Snake-eating turtle, Yellow-margined box turtle, and Golden-headed turtle. Taxonomically, it has been called Cistoclemmys flavomarginata, Cuora flavomarginata, and Cyclemys flavomarginata. The Integrated Taxonomic Information System uses Cuora flavomarginata.


Yellow-margined Box Turtle has a highly domed shell, the carapace and plastron of which are a dark brown, excepting a cream-yellow stripe on the vertebral keel. The edge of the plastron is lightly pigmented due to the marginal scutes' and plastral scutes' lighter pigmentation near their edges. The skin on the limbs is brown in color while the top of the head is a pale green. Each side of the head has a yellow line extending from behind the eye backward. The skin beneath the head and between the limbs is a lighter pink-ish color.


The name box turtle refers to C. flavomarginata's ability to bring the plastron to the edges of the carapace. This is enabled by a hinge on the plastron and ligaments connecting the carapace and plastron, which allows for limited movement. The forefeet have five claws, while the rear have four.


The external difference between male and female Yellow-margined Box Turtle is slight. Males have a broader tail than females; it is almost triangular in shape.

Painted Batagur


True Wild Life | Painted Batagur | The Painted Batagur is the largest turtle living in fresh water. They are in danger of extinction because people take them as pets or to eat, and because of the deteriorating environments in and around the rivers they live in. Painted Batagurs live on the Malaysian peninsula, Sumatra Island, and Kalimantan Island.


Painted Batagurs live in rivers and sometimes go near the ocean where the seawater mixes with the fresh water. They also lay eggs in sandy beaches like Green Turtles. Young Painted Batagurs eat other animals and plants. Once they become adults, their diet changes to mainly leaves and other plants.


The number of Painted Batagurs is declining because people capture them to eat, in addition to river water pollution and deteriorating surrounding environments. In Thailand, where the Painted Batagur is on the brink of extinction, there are strict restrictions against their capture, sale, or purchase. Additionally, there are efforts to increase their number by breeding. Although there are international restrictions against the sale and purchase of Painted Batagurs, there are still many efforts that need to be made to recover their numbers, such as making river environments safe for living in.

Ryukyu Black-breasted Leaf Turtle


True Wild Life | Ryukyu Black-breasted Leaf Turtle | The Ryukyu black-breasted leaf turtle or Ryukyu leaf turtle, Geoemyda japonica, is a species of turtle in the family Geoemydidae (formerly Bataguridae). It is endemic to the Ryukyu Islands in Japan. In 1975 the species was designated a National Natural Monument of Japan. It grows to approximately 5–6 inches long. In captivity it feeds on worms, snails, insects, and fruit. Due to its rarity and very attractive appearance, this species is highly coveted by turtle collectors worldwide.


The Ryukyu black-breasted leaf turtle  has a flattish brown, chestnut, mahogany or tan carapace that is serrated front and rear, with three keels. The plastron is black or dark brown with yellow or yellow-cream rings. The skin of the Black-breasted Leaf Turtle is dark with colored spots or mottles, and females have a yellowish-cream stripe down each side of the head. Its feet are only semi-webbed, and it has large bulging eyes with white irises.


At first it was considered a subspecies of Geoemyda spengleri, and named Geoemyda spengleri japonica. It was redescribed as a separate species and given its current binomial name in 1992.

Burmese Starred Tortoise

 
True Wild Life | Burmese Starred Tortoise | The Burmese star tortoise (Geochelone platynota) is becoming extinct in its native Myanmar (Burma). Burmese Starred tortoises look like another land turtle called Indian Starred tortoise. But if you look closely, you will see the Burmese Starred Tortoise's shell is thinner and flatter than the Indian Starred tortoise.


Burmese Starred Tortoises are omnivorous as they eat both plants and animals. But we are still not sure what they eat in the wild. The Burmese Starred Tortoise sticks to his name. His shell's pattern is beautifully star-studded. It is said that in the early 20th century, the Burmese Starred Tortoise was high in number. However, soon after, they were caught for food. Their woods were clear-cut and now they are endangered.


And the greatest problem today is they are being caught as pets. In Myanmar, it is illegal to capture and export the Burmese Starred Tortoise. Despite this, large numbers of Burmese Starred Tortoise are being sold in Japan, China, and Thailand. The first step is to severely punish lawbreakers and smugglers.

Giant Armadillo


True Wild Life | Giant Armadillo | The giant armadillo is the largest of all armadillos and found in South America, east of the Andes, from northwestern Venezuela to northeastern Argentina. Adults grow as long as 35 inches and can weigh over 70 lb. The necks and backs of armadillos are covered with flexible carapaces (shells) consisting of 14 to 17 moveable bands of horn and bone. Their heads are also covered with a similar oval shield. The head, tail and lower edges of the giant armadillo are nearly white, and the rest of the body is dark brown. Underneath the carapace, its naked body appears wrinkly and pinkish in color. It has powerful claws with a very large central claw similar to the claw of the giant anteater. Giant armadillos are very fast on the ground and can sometimes balance themselves on their hind legs and tails, with their forefeet off the ground.


Giant armadillos prefer to live in burrows near water in grassland, brushland, woodland, and forests where termite mounds are present. It is believed that they are very good swimmers. They are active mainly at night and prefer to sleep in the daytime. They are very powerful and quick diggers enabling them to find insects and escape predators by hiding in the ground. Preferred diet is ants and termites, but they will also eat other insects, worms, spiders, larvae, snakes, and carrion. Giant armadillos can consume entire termite mound populations once discovered. Little is known about the mating behavior of this species. Other armadillo species are known to pair up during mating season and share a burrow. Females give birth to one to two young after a gestation period of 120 days. The young armadillos are born with tough leathery skin to protect them from dangerous predators.


Giant armadillos have suffered from loss of habitat due to agricultural development and human settlement, and they are also overhunted by humans for food. Some are killed by farmers because they are thought to damage crops. This species was listed as endangered in 1976, and the continued study of the species and its habitat is necessary to plan additional conservation efforts.
