Southern Cassowary Interesting Facts

What type of animal is a southern cassowary?

The southern cassowary (Casuarius casuarius) is also known as the two-wattled cassowary or the southern double wattled cassowary. It is a bird with a vast structure and red-colored wattles hanging down from its neck, with sharp three-toed feet.

What class of animal does a southern cassowary belong to?

Like many birds and reptiles, southern cassowaries belong to the Aves class. They are considered to be the biggest Australian bird.

How many southern cassowaries are there in the world?

Sadly, the number of southern cassowaries in the world is reducing day by day. They are primarily found in Queensland in Australia, New Guinea, and Indonesia. In 2014, reports in Australia counted just 4,000 of these flightless birds.

Where does a southern cassowary live?

Many of these double-wattled cassowaries live in tropical rainforests in Queensland. They also like to stay in places near beaches, woodlands, and mangroves.

As they depend primarily on different types of fruit and plants for food, they build shelters in mixed environments where finding food is less of a problem. More generally, we find these powerful birds in Australia, Indonesia, and Papua New Guinea.

What is a southern cassowary's habitat?

The habitats of southern cassowaries are in the rainforest, Melaleuca swamps, and mangrove forests. They depend mostly on fallen fruit found on the forest floor and hence choose locations where food is abundant. Cassowaries are sometimes called seed carriers because they carry seeds from trees and plants in the rainforest from one place to another.

Who do southern cassowaries live with?

Southern cassowaries like to live alone. These solitary animals create a large home in dense forests, so it is normal for these birds to stay away from one another. Only during the breeding season, do cassowaries come into contact with each other.

How long does a southern cassowary live?

Along with ostriches, the cassowaries are considered among the most dangerous birds globally. A southern cassowary lifespan averages between 40-60 years. But deforestation, road kills, and clearing of lands is leading to the decline of cassowaries.

How do they reproduce?

The breeding season starts between May and June. Female cassowary birds follow the polygynandry method, mating with more than one male partner during each breeding season, so each female lays between three and eight eggs.

Southern cassowary eggs are laid in different colors like bright green and pale green-blue eggs. Do you know any other birds that lay such colorful eggs?

By laying these green eggs, the female bird's job is complete, and males take up the responsibility for incubating the eggs for approximately 50 days.

They add and remove litter to these eggs in order to regulate the temperature, and, once hatched, they protect their little birds from dogs, humans, and other predators for nine months, as well as provide them with food and water. The father cassowary will not leave the young chicks even to meet his own basic needs.

What is their conservation status?

The southern cassowary bird is considered endangered in Queensland. But, the IUCN (International Union for Conservation of Nature) has changed these birds' conservation status from Vulnerable to of Least Concern recently.

The reasons for the decrease in this species' population are road kills, clearing of lands, and threats from feral pigs and dogs. If the large-scale destruction of forests is stopped, we have a better chance of saving these species.

How do they communicate?

Southern cassowaries stay in the dense tropical rainforest so the frequency of the southern cassowary call is very low and quiet. The sounds that they make are called booms. While making this sound, they try to bend their head down to the ground.

Their casque also plays a vital role in the sound resonating. They communicate only during the breeding season or when detecting dangers. Some people say that their sound resembles that of a growling mammal.

The southern cassowaries (also known as the Casuarius casuarius johnsonii) are massive birds with long bent necks and a helmet on their head called a casque. The average southern cassowary height is 5.5 ft (200 cm), as tall as some humans.

Male cassowaries weigh 121 lb (55 kg), and females weigh 167 lb (76 kg). The southern cassowary is approximately 50 times bigger than the hummingbird.

There is no particular name for the cassowaries' female and male birds. The females are simply called female cassowaries, and the males are called male cassowaries. A group of cassowaries is called a shock.

What do they eat?

Is the southern cassowary omnivore? Yes, the southern cassowary's diet consists mainly of fallen fruits on the forest grounds and small vertebrates. They also eat fungi, plants, seeds, and invertebrates.

During hot seasons, cassowaries drink water by bending their head down and then lifting it to swallow. They swallow any fruit as a whole. They also often try to eat their poop for absorbing the remaining nutrients from undigested fruits.

Are they loud?

No, the southern double-wattled cassowaries are not at all loud. They make low-frequency sounds during the breeding season to attract mates or to attack enemies. These rumbling and booming sounds are very low in frequency.

Would they make good pets?

The southern cassowary (Casuarius casuarius) is considered one of the most dangerous birds in the world. Though they are colorful with adorable looks, they are not good pets. These wildlife species like to spend time in solitude and they can become aggressive when threatened.

A southern cassowary attack can be very dangerous. They use their claws to attack their predators, and once a cassowary has even killed a human! The southern cassowaries kill predators quickly, using their sharp claws.

The southern cassowary kick can be lethal. These birds don't like human interference in their lives and they don't want to be disturbed and provoked.

Southern cassowaries have hidden spikes in their wings, but even these dangerous birds have predators, including crocodiles, dogs, and humans. Their eggs are green in color.

This green color is thanks to the pigment present in their eggshells. This color helps to protect the eggs from southern cassowary birds' predators in the rainforest. The male southern cassowary plays a vital role in his chicks' growth beyond the initial breeding season.

As they live in dense forests, these birds adapt to the environment, nature, and climate of the forests. Just one of many southern cassowary adaptations is that their fur-based feathers protect them from thorns and spikes present in their surroundings.

Though they cannot fly, these animals are experts in swimming and sprinting.

Why is the cassowary so dangerous?

Cassowaries are considered to be dangerous flightless birds. When provoked by humans or enemies, the southern cassowary attacks them with its claws.

Like ostriches and emus, they have very sharp, knife-shaped talons and, as we know, they are great sprinters. The southern cassowary attacks at a speed of 30 mph (48 kph), and with the help of their sharp nails, they scratch upwards and downwards on their enemies.

They need to be handled with great care, as they won't attack anyone without reason.

Why is the southern cassowary endangered?

The southern cassowary is not listed as Endangered on the ICUN red list, but their number reduces day by day. The numbers are reducing for many reasons.

Road kills and land clearings are among the main reasons for the decreasing numbers of this species. They are an essential species to the environment because they are seed carriers that carry seeds of different fruits from one place to another.

In doing this, they help to promote the growth of dense forests. To save these valuable species, the Australian government has taken some measures, including growing different plant species in the rainforest to encourage biodiversity.
